2dabc6ad62bff830005c83fe71da531b59c593d2 Mon Sep 17 00:00:00 2001 From: counterweight Date: Fri, 11 Sep 2026 22:43:55 +0200 Subject: [PATCH 33/95] uptime-kuma: add uptime_kuma_enabled flag and make monitoring blocks inert MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removing the credentials would otherwise break these playbooks mid-deploy: they template uptime_kuma_password with no assert to stop them first. 100 tasks are now guarded by uptime_kuma_enabled (false), so deployments run normally and the monitoring sections skip. A further 28 tasks were already self-guarding on monitor_setup/push_url being defined; verified that a skipped task's registered variable makes those skip cleanly rather than error. The blocks are kept on purpose — the health-check logic is the durable part and should be rewired to whatever replaces Uptime Kuma.

Nothing calls it yet; this commit only adds the role. Verified by rendering all 10 sites through the template and diffing against what the current playbooks produce: 9 of 10 byte-identical. The tenth is datum-gateway, where the resolvers comment is standardised, rewriting one comment line Caddy ignores. Then dry-run against the live hosts (--check, nothing written): - vipy: forgejo, vaultwarden, lnbits, personal-blog, ntfy-emergency-app all report ok/unchanged against the real files - watchtower: ntfy renders identical via caddy_site_body, blank line and {host}{uri} placeholders intact - spacey: headscale renders identical when given the config that is actually running - memos, mempool, datum-gateway report changed - the comment, as expected All 14 site files on all 3 hosts confirmed unchanged afterwards. Two things the build turned up: - Ansible does not template dict *keys*, so caddy_site_basic_auth is a list of {user, hash}. As a dict, a Jinja username passes through literally. The assert refuses a mapping. - `caddy validate` does accept a single site fragment - rc=0 on a good one, rc=1 with a line number on a broken one. This was the plan's one untested claim. A failed validate leaves the live file untouched. The reload is now a handler, so it fires once at end of play rather than immediately; anything needing the new config live mid-play must flush_handlers first.

Verified: --check before and after the edit reports the same three unrelated tasks as changed, so the edit introduces nothing. Real run leaves all 14 site files on all 3 hosts byte-identical, and the blog still answers HTTP 200. A second consecutive run reports the site task ok with the handler not firing. Side effect worth noting: the playbook no longer has a perpetually-changed task. `command: systemctl reload caddy` always reported changed; the role's handler only fires when the file actually moves.

All three removed a byte-identical 23-line block (verified by md5 of the diff with the service name normalised) and gained the same 7-line include_role call. The caddy_sites_dir self-reference goes with it. Verified in check mode, nothing applied to the hosts yet: - ntfy-emergency-app: site task ok, changed=0 - vaultwarden: site task ok; the one changed task is a pre-existing always-restarts fail2ban step, identical before the edit - forgejo: check mode cannot run this playbook at all - get_url does not download in check mode so the next task fails on "Source /tmp/forgejo not found". Confirmed identical before the edit. Covered instead by the Stage 2 dry-run, which ran the role against vipy with forgejo's real parameters and reported ok/unchanged. All 14 site files on all 3 hosts still byte-identical. Real runs for these three are still outstanding.

Verified: - lnbits: full --check, site task ok, byte-identical to the live file - memos, mempool: --check --diff via --limit edge shows exactly one added line each, the standardised MagicDNS comment. Both playbooks fail earlier in check mode on their VM play ("Extract memos binary", the same download-does-not-happen-in-check-mode artifact as forgejo), but the edits are confined to the hosts: edge play - memos at line 169+, play 2 starts at 159; mempool at 617+, play 2 starts at 606. The added comment means the next real run of memos/mempool rewrites one comment line. Those two host files were already stale against their playbooks before this change. All 14 site files on all 3 hosts still byte-identical.

No hand-rolled Caddy plumbing remains anywhere: `grep sites-enabled` outside roles/ returns nothing, and so does `grep "systemctl reload caddy"`. ntfy uses caddy_site_body for its plain-HTTP listener and @httpget redirect. Verified ok/unchanged against watchtower; the one other changed task is a pre-existing "Update APT cache". datum-gateway keeps a whole-Caddyfile validate after the role call. The role validates its own fragment, but only a whole-file validate catches a conflict between two sites, and this playbook was the only one that ever had it. Its two debug tasks that echoed command output are gone with the commands. headscale is the one that mattered. Its playbook wrote `reverse_proxy localhost:8080`, but spacey is actually running a /admin* route in front of Headplane behind Caddy basic auth. Running that playbook would have deleted the admin route and its auth - a hazard that predates this work. It now renders the config that is really there, verified ok/unchanged via --start-at-task (the play cannot reach Caddy in check mode: "Install headscale package" fails because the .deb is not really downloaded, before and after this edit alike). Supporting changes for headscale: - headscale_ui_password_hash added to infra_secrets.yml and the identical group_vars/all/vault.yml, read from the live config on spacey. The vault already had headscale_ui_username (= counterweight, confirmed) and headscale_ui_password; I did not verify the password is the plaintext of this hash. - headplane_port added to headscale_vars.yml. - The role's handler now sets become: true. Handlers do not inherit become from the task that notified them, and this play runs become: no. - The include uses `apply: become: yes`; `become:` on an include_role is rejected outright. All 14 site files on all 3 hosts still byte-identical.

Verified before touching any playbook: all six live units on vipy reproduced byte-identically. Then --limit edge --check per playbook - bitcoin-knots and fulcrum changed=0; datum-gateway changed=2, both attributable to the already known caddy_site comment line and the Reload caddy handler it triggers. The 6 units and 14 Caddy files on the hosts are byte-identical afterwards. PLAN_4 claimed these three plays had "no behavioural drift at all". That was wrong - it came from a diff truncated by head -60. The live bitcoin-p2p-proxy units carry four settings this playbook never wrote: .socket Documentation=, FreeBind=true .service Documentation=, TimeoutStopSec=5, StandardOutput=journal, StandardError=journal FreeBind is the one that matters: it lets the socket bind to an address that is not up yet, so without it the socket can fail to start on boot. Running the bitcoin-knots playbook would have stripped it. Same class of hazard as headscale. The role expresses all four; bitcoin-p2p is the only caller that passes any. Also: UFW treats the rule comment as part of the rule. datum-stratum's live comment is "DATUM Gateway Stratum public access" but the role's derived default produced "DATUM Stratum public access", which rewrote the rule. Caught in the dry-run; datum now passes the comment explicitly. Two deliberate differences from the original, both documented in the README: ignore_errors: yes on the upstream check became failed_when: false, and the handler restarts the .socket, which drops connections open through it - it fires only when a unit file actually changes. The inert Uptime Kuma TCP monitor blocks stay in the playbooks rather than being pulled into a new role (12/12/18 guarded tasks).

The 14 Caddy site files and 6 proxy units on the hosts are byte-identical to the Stage 0 baseline. Seven play names still said "on vipy" while the play targeted a group. Renamed to "on the edge host" - the last place a play claimed a hostname after Plan 2. Documented the four vhosts in /etc/caddy/sites-enabled that no playbook writes (uptime-kuma, arbretstaging, bitcoininfra, scriberr) in the caddy_site README. None deleted. uptime-kuma.conf was going to be deleted as dead config. It is not dead: the louislam/uptime-kuma container is STILL RUNNING on watchtower - created 2026-02-07, restart=unless-stopped, healthy - and uptime.contrapeso.xyz returns 302, not the 502 a dead backend would give. The "decommissioning" retired the Ansible code and the vault credentials, not the service. PLAN_3 claimed "the tokens died with the server"; that is corrected there. The Caddyfile.* backups are kept: one per host, Nov-Dec 2025, not churning, and the only record of each Caddyfile before the import line was added.

Applies the Plan 6 Stage 0 decision: keep whatever determines whether the service is healthy, drop the Uptime Kuma specifics, make the reporting point pluggable. Gone from the role: the embedded Python that created monitors over the Kuma API, the /tmp credentials file, token extraction, the systemd Environment= rewrite, and 8 `when: uptime_kuma_enabled` guards. What remains is the check itself, its log, the systemd unit and timer, and an honest exit code - `systemctl is-failed forgejo-runner-healthcheck.service` now answers the question with no monitoring system involved at all. Reporting is one variable, healthcheck_push_url, empty by default. Any endpoint that accepts an HTTP ping plugs in there. A pull-based monitor wants it left empty and reads unit state instead. PREMISE CORRECTION: Uptime Kuma is NOT dead. Plan 3 recorded "48 push timers curling an endpoint that no longer answers" and Plan 6 said the check had "nowhere to report to". Both wrong - 24+ push scripts across 11 hosts are pushing successfully right now (HTTP 200). Only the Ansible code and the vault credentials were decommissioned; the service never stopped. So the existing push URLs were harvested into a vaulted healthcheck_push_urls dict and are preserved, keeping this refactor behaviour-neutral. Retiring Kuma stays a deliberate act rather than a side effect. PLAN_3 and PLAN_6 are corrected. Verified: - task-list diff vs the old playbook shows ONLY the five Kuma tasks removed, everything else identical and in the same order - first run ok=22 changed=1 (the rewritten health script); both systemd units and forgejo-runner.service came back ok, so the templates reproduce the previous files byte-for-byte - second run ok=22 changed=0, fully idempotent - still reports "Ping sent successfully (HTTP 200)" from a script containing zero Uptime Kuma references - the 4 skipped tasks are genuine already-configured guards, checked not assumed Two things for the next service: - import_tasks, not include_tasks. Dynamic includes are opaque to --list-tasks, which is the primary verification tool here; the first attempt produced a useless diff. - `Assert runner is running` was guarded by uptime_kuma_enabled and so had not run since the decommissioning. It is not monitoring, it is the deployment checking its own work - the deprecation banner swept it up with the Kuma plumbing, and a runner that failed to start was deploying "successfully" in silence. Ungated now. The banner was applied to contiguous blocks, so read every uptime_kuma_enabled guard and ask whether it is monitoring or deployment.

Task-list diff vs the old playbook shows ONLY the eight Uptime Kuma tasks removed - everything else identical and in the same order. phoenixd holds a Lightning node, so the run was checked against a pre-flight: before: channel 6c25fa83..., balanceSat 1550723, capacitySat 3114830, blockHeight 966692, active since 2026-09-02 after: identical, and still active since 2026-09-02 - it did NOT restart `Create phoenixd systemd service` came back unchanged, which is what proves the template reproduces the live unit byte-for-byte. changed=3 was the health check script, its unit (Environment rename), and the timer restart. Second run: changed=0. Two things the conversion fixed, both symptoms of the deprecation banner having been applied to contiguous blocks rather than to individual tasks: - The health check logged "ERROR: UPTIME_KUMA_PUSH_URL not set" on every fire - about 1,400 times a day - because its Environment= was emptied at decommissioning. The exit code was still correct so nothing was broken, but it is exactly the kind of noise that trains you to ignore a log. An unset push URL is now normal and silent. - `Enable and start phoenixd health check timer` was guarded by uptime_kuma_enabled and so had not run since the decommissioning, while the timer itself was still live on the host from before. Ansible had quietly stopped managing something that was still running. Ungated. Noted, not changed: seed.dat is mode 0644 on the host. That is phoenixd's own doing, but it is a Lightning seed and worth tightening.

That is infra definition, and it existed only on one laptop. Meanwhile the committed terraform.tfvars.example still advertised web1/db1. Split at the credential boundary: the provider auth triple stays in the gitignored terraform.tfvars, everything else moves to vms.auto.tfvars, which is committed and auto-loaded (no -var-file needed). terraform.tfvars.example is now credentials-only. `tofu plan` reports no changes. State stays ignored — it carries cloud-init attributes and should not be in git.

Three health checks are kept, not collapsed: Mempool is three moving parts and knowing which one is down is the point. Each has its own script, unit, timer and push_url, driven by a mempool_healthchecks list. The Uptime Kuma specifics are gone - the embedded Python creating monitors over the API, the /tmp credentials file, the push-URL file read back and parsed, three Environment= rewrites - and the three live push URLs are preserved from the vault, so reporting is unchanged. `Enable and start health check timers` and `Display deployment status` were both guarded by uptime_kuma_enabled despite being deployment tasks. Third service in a row with that pattern: the deprecation banner was applied to contiguous blocks, so anything sitting near the push plumbing was disabled with it. Ungated. TWO OWNERSHIP PROBLEMS, different in kind: - MINE: I wrote `owner: root` on docker-compose.yml where the original says `owner: "{{ ansible_user }}"`. A straight violation of extract-mechanically- change-nothing, caught only by reading the check-mode diff line by line. Reverted to match the original. - PRE-EXISTING, and dangerous: the playbook declared `owner: "{{ ansible_user }}"` (1000) on the MariaDB data directory, which the container owns as uid 999. Confirmed against `git show HEAD:` before concluding it was not mine. It had drifted since the containers were created and went unnoticed because the playbook had not been run since. This was not academic. The first real run pulled a newer mariadb:10.11 and recreated mempool-db; with the chown still in place MariaDB would have come back to a data directory it could not write. The role now ensures the directory exists and leaves ownership to the container. Verified after the run: /opt/mempool/mysql is still 999:999 and all three containers are healthy. This is a deliberate behaviour change, not part of the extraction. It is in this commit rather than a follow-up because the faithful version was never safe to run, so there was no intermediate state worth recording as verified. mempool_frontend_port moved to services_config.yml: two hosts need it (this role deploys the frontend, the Caddy play proxies to it from the edge host) and a role default is invisible to the second play. caddy_site's parameter assert caught this loudly - "'mempool_frontend_port' is undefined" - rather than silently. Verified: check-mode diff clean apart from unavoidable check-mode artifacts; first run ok=24 changed=5, zero failures; second run changed=2 - the two bare `command:` tasks (pull, compose up) that have no changed_when and always report changed. That is the idempotent floor. All three health checks report ExecMainStatus 0 with their push URLs intact.

Verified: fulcrum untouched - active since 2026-07-29 (no restart), 192G datadir, height 966842, bitcoind and db_mem unchanged on disk. Second run changed=1 (the arming run, changed_when: false aside). vipy changed=0. THREE PRE-EXISTING LANDMINES the check-mode diff caught, any of which a faithful extraction would have detonated: - bitcoin_rpc_host was "192.168.1.140", commented "IP of knots_box_local". But .140 is fulcrum-box ITSELF; knots-box is .135. The DHCP leases had reshuffled - the fifth instance of this same disease in this estate. The live config had been hand-corrected to knots-box; running the playbook would have reverted it and pointed Fulcrum at itself. Now addressed by Tailscale name. - The `Restart fulcrum` handler was guarded by uptime_kuma_enabled, so the three tasks that notify it (SSL cert, fulcrum.conf, systemd unit) could not restart anything. A config change applied to disk, reported success, and silently never took effect. That is worse than the other banner casualties: it makes the deployment itself lie. Ungated. - db_mem was about to go 2048 -> 4448 (75% of 5931MB RAM), leaving ~1.4GB for the OS and Fulcrum's non-cache memory. The live value had been hand-tuned down. fulcrum_db_mem_mb_override pins it. Note set_fact outranks role defaults, so the calculation itself has to honour the override. MY OWN ERROR, third instance: retyping `copy:` as `template:` lost `owner:` on the banner and on fulcrum.conf. Rather than keep catching these by eye, every managed path's owner/group/mode is now compared against `git show HEAD:` mechanically - 12/12 match. The health check timer had not fired since 2026-02-17 while reporting `active` and `enabled`. It is OnBootSec + OnUnitActiveSec with no OnCalendar: OnBootSec elapses once, and OnUnitActiveSec needs the SERVICE to have run this boot to have anything to schedule from. Restarting the timer does not supply that; running the service does, so the role now runs the check once after enabling. Also dropped `Requires=fulcrum.service` from the timer - on a timer that means "stop watching when the watched thing stops". Diagnostic note: NextElapseUSecRealtime is always empty for a monotonic timer, so it reads as broken even when healthy. I misread it once and wrongly called the timer dead. Use NextElapseUSecMonotonic or systemctl list-timers. fulcrum_ssl_port and fulcrum_tailscale_hostname moved to services_config.yml - the socket-proxy play on the edge host needs them and a role default cannot reach a second play.

Verified after a real run: bitcoind still active since 2026-08-19 (NO restart), chain at 966844 blocks / 875 GB, DATUM config intact, dbcache still 200, health check timer firing again. changed=3, all health-check. vipy changed=0. ⚠ THE BIG ONE: the playbook would have deleted the mining integration. bitcoin.conf on the node carries a section that was hand-added and was missing from the template entirely: blockmaxsize=3985000 blockmaxweight=3985000 blocknotify=killall -USR1 datum_gateway maxmempool=1000 blockreconstructionextratxn=1000000 blocknotify is how datum_gateway learns a new block landed. Running the old playbook would have stripped all of it and solo mining would have carried on against a stale template - a silent failure that costs money rather than raising an error. Also dbcache 200 -> 3528 (hand-tuned down; the calculation wants 90% of RAM) and logging moved off the file. All now reconciled, dbcache behind bitcoin_dbcache_mb_override. bitcoin-knots and datum-gateway are ONE SYSTEM. Noted in the README. AND MY OWN FIX MADE IT MORE DANGEROUS. The `Restart bitcoind` handler was guarded by uptime_kuma_enabled, so it had been inert: bitcoin.conf and the systemd unit both notify it and neither could restart anything - a config change applied to disk, reported success, and never took effect. Ungating that is right, but it converts "wrong config sitting inertly on disk" into "node restarted onto a config that breaks mining". The ungating had to land WITH the template reconciliation, not before it. It also raises the bar permanently: any residual template/live difference now restarts a Bitcoin node on every run. Four rounds of --check --diff to reach changed=0 - the DATUM section, an explanatory comment that was rendering into the deployed config (now a {# #} Jinja comment), a "# Pruning (optional)" comment the live file had, and one trailing blank line. The build path is 32 tasks all guarded by `not bitcoind_binary_exists.stat.exists`, so a converged host skips the 30-60 minute compile and both `state: absent` deletions. Those target /opt/bitcoin-knots/{source,bitcoin-}; the chain is in /mnt/knots_data and is never touched. Signature-verification tasks copied verbatim. The health check timer had last fired 2026-08-09 while reporting active/enabled - same OnBootSec + OnUnitActiveSec dead chain as fulcrum. The role runs the check once after enabling to supply the reference the timer schedules from. Ownership parity checked mechanically against `git show HEAD:`, keyed by TASK NAME rather than path - keying by path gave a false positive, because bitcoin_knots_source_dir is created with ownership and later removed with state: absent, so whichever task comes last wins and that differs between one file and five. 13/13 match. bitcoin_p2p_port and the tailscale hostname moved to services_config.yml for the socket-proxy play on the edge host.

+# `bitcoin_knots` + +Builds Bitcoin Knots from source with PGP + SHA256 verification of the release +tarball, runs it as a full node on `knots-box`, and keeps a health check on a +systemd timer. The second play in the calling playbook publishes the P2P port +from the edge host via `socket_proxy`. + +Converted from `deploy_bitcoin_knots_playbook.yml` (892 lines) under Plan 6. The +playbook is now 40 lines. + +## The build is guarded; the chain is never touched + +`build.yml` is 32 tasks, every one carrying +`when: not bitcoind_binary_exists.stat.exists`. On a host that already has the +binary the whole download / verify / 30-60 minute compile skips — **including the +two `state: absent` deletions**, which target `/opt/bitcoin-knots/source` and the +extracted build directory. + +The chain lives elsewhere and nothing here touches it: + +| | | +|---|---| +| `bitcoin_knots_dir` | `/opt/bitcoin-knots` — build tree, safe to delete | +| `bitcoin_data_dir` | `/var/lib/bitcoin` — config, logs, wallets | +| `bitcoin_large_data_dir` | `/mnt/knots_data` — **~875 GB of blockchain** | + +The signature-verification tasks are the security control of this role. They are +copied verbatim; do not "simplify" them. + +## ⚠ This node is half of the mining setup + +`bitcoin.conf` carries a DATUM Gateway section that was hand-added on the node +and was **missing from the playbook's template**: + +```ini +blockmaxsize=3985000 +blockmaxweight=3985000 +blocknotify=killall -USR1 datum_gateway +maxmempool=1000 +blockreconstructionextratxn=1000000 +``` + +`blocknotify` is how `datum_gateway` learns a new block landed. Running the old +playbook would have deleted all of it, and solo mining would have carried on +grinding against a stale template — a silent failure that costs money rather +than raising an error. The template now carries it behind +`bitcoin_datum_gateway_enabled`. + +**bitcoin-knots and datum-gateway are one system, not two services.** Changing +either config means thinking about both. + +## The restart handler, and why exactness matters now + +The hand-written `Restart bitcoind` handler carried +`when: uptime_kuma_enabled | default(false)`, so it had been inert since the +decommissioning: `bitcoin.conf` and the systemd unit both notify it and neither +could restart anything. A config change applied to disk, reported success, and +never took effect. + +It is ungated here — which raises the bar for the template. **Any** residual +difference between the template and the live file, down to a trailing newline, +means the task reports `changed` and restarts a Bitcoin node on every run. It +took four rounds of `--check --diff` to reach `changed=0`: the DATUM section, an +explanatory comment that was rendering into the deployed file (now a `{# #}` +Jinja comment), a `# Pruning (optional)` comment the live file had, and one +trailing blank line. + +## `dbcache` + +Computed as 90% of RAM unless `bitcoin_dbcache_mb_override` is set. The live node +was hand-tuned to **200 MB**; the calculation produces 3528.

Verified after a real run with zero miners connected: datum-gateway restarted cleanly onto the reformatted config, deployed config.json semantically identical to what was there (pool_address bc1qvrj3g84..., pool_pass_* false, ports unchanged), health check timer firing, and the Knots side untouched - bitcoind still up since 2026-08-19 with blocknotify intact. TWO PIECES OF DRIFT WHERE THE NODE WAS RIGHT, both confirmed with the operator: - datum_mining_address: the vault held bc1qdse9dsg... while the node had been mining to bc1qvrj3g... since 2026-08-08. This is WHERE BLOCK REWARDS ARE PAID. And unlike fulcrum and bitcoin-knots, the `Restart datum-gateway` handler here was never gated, so the stale value would have applied immediately rather than sitting inert on disk. - pool_pass_workers / pool_pass_full_users: false on the node, true in the vars file. Both corrected in the vault and role defaults with notes recording why. Comparing this config needs semantics, not text: the live file is single-line JSON and the template renders pretty-printed, so a textual diff is pure noise. Rendering it and comparing parsed JSON is what surfaced both differences. config.json carries bitcoind.rpcpassword and api.admin_password, and --diff prints rendered content - so `--check --diff` put them on the terminal. The task now sets diff: false by default (-e datum_reveal_config=true to opt in). Those two should be rotated. I also mis-reported pool_pass_workers/pool_pass_full_users as exposed credentials because my masking matched "pass" in the key name. They are BOOLEANS, and mining.pool_address is a Bitcoin address, public by nature. Only the two real passwords above were exposed. `Configure cmake build` and `Compile datum_gateway` are bare command: tasks with no changed_when, so they recompile on every run. The build is reproducible - Install datum_gateway binary sees identical content and leaves the installed binary's timestamp alone - but it is wasted work each time. Documented as the idempotent floor. Ownership parity checked mechanically against `git show HEAD:` keyed by task name: 7/7 match, 9 Kuma tasks dropped. This completes Plan 6 Stage 2: all six services in the list are roles.

But they had rotted. De-Kuma, following the pattern of the six service roles: Both plays opened with an assert on uptime_kuma_username/password, which were removed from the vault, so both failed before doing anything. Dropped that, the two embedded Python monitor-creation scripts, and their /tmp cleanup. Kept every check, threshold and systemd timer - those are the durable part. Reporting is now generic: `healthcheck_push_url` goes into the unit as Environment=HEALTHCHECK_PUSH_URL and the script reads ${HEALTHCHECK_PUSH_URL:-}, treating empty as normal rather than an error. The exit code is the real answer; systemd keeps it. Both scripts now also report status=down on failure instead of only going silent. Live push URLs harvested into the vault so nothing observable changes for ZFS. Three live bugs found while check-diffing: 1. 32_zfs would have DE-REGISTERED the Proxmox storage. `pvesm remove` was gated on the storage existing and `pvesm add` on it NOT existing - mutually exclusive - so a real run removed the proxmox-tank-1 entry backing every VM and never put it back. It would also have dropped `mountpoint /var/lib/vz`, which the live entry has and `pvesm add` does not set. Registration is now add-only. 2. zfs_disk_1 named ata-...WX11TN0Z, a disk no longer in the machine. The live mirror is WX120LHQ + WX11TN2P; a leg was replaced and the repo never caught up. Inert behind `when: zfs_pool_exists.rc != 0`, but wrong on any disaster-recovery run. This is the seventh instance of an identifier written down once whose hardware later moved. 3. 34_nut has NEVER been applied to nodito - no /etc/nut file carries the "Managed by Ansible" marker; they were written by hand in January 2026. The vault held the literal CHANGE_ME_TO_SECURE_PASSWORD, so applying it would have overwritten a working upsd/upsmon auth pair with a placeholder and restarted NUT, leaving the hypervisor's UPS unable to trigger a clean shutdown on mains loss. The Kuma assert was the only thing stopping that, so removing it without a replacement would have armed the gun: there is now an explicit assert that refuses to run on the placeholder. The real password is in the vault and `Configure upsd users` check-diffs clean. Templates reconciled with the live files first, so applying 34_nut is close to a no-op: added `maxretry = 3` to ups.conf and OFFDURATION / RBWARNTIME / NOCOMMWARNTIME / FINALDELAY plus quoted POWERDOWNFLAG to upsmon.conf. The only substantive additions left are the NOTIFYMSG/NOTIFYFLAG syslog lines. /usr/local/bin/ups-heartbeat.sh on the box is an orphan - mode 0644, not executable, referenced by no unit and no cron entry - but its push token belongs to a monitor that still exists and answers, so that monitor has had no heartbeat since January. Harvested as healthcheck_push_urls.ups; applying this play is what will finally feed it. Finish the host_vars migration: infra/nodito/nodito_vars.yml was byte-identical to host_vars/nodito/main.yml. Deleted it, moved nodito_secrets.yml to host_vars/nodito/vault.yml, and stripped the dead vars_files entries from all three playbooks. Extract the 13 inline `content: |` blocks to infra/nodito/templates/, pulled via a YAML load rather than retyped. 681+582 lines become 313+344 plus templates. Ownership parity against HEAD checked mechanically: no owner/group/mode drift on any surviving task. Neither playbook has been applied. ZFS play 2 check-runs failed=0 with two changes: the script rewrite (the deployed one is a hand-edited DEBUG VERSION with `set -x`) and the Environment line.

Mon Sep 17 00:00:00 2001 From: counterweight Date: Sun, 13 Sep 2026 20:58:46 +0200 Subject: [PATCH 59/95] ansible: delete the duplicated vars files, move globals to group_vars/all Three files existed only as second copies of things group_vars/all already auto-loads, and 34 playbooks named them in vars_files: - which outranks group_vars, so the copies won. The day someone edited one and not the other, those plays would silently keep the stale value. infra_vars.yml was already drifting: group_vars/all/main.yml had grown age_backup_recipient and backup_pull_public_key that it lacked. infra_vars.yml - a strict subset of group_vars/all/main.yml infra_secrets.yml - decrypts byte-identical to group_vars/all/vault.yml infra_secrets.yml.example - documented Uptime Kuma credentials as the reason the file exists, which stopped being true Deleted, along with 62 vars_files entries across 34 playbooks (12 of which named ../../group_vars/all/main.yml directly - same defect, a vars_files entry duplicating an auto-loaded file at higher precedence than the file itself). Checked before touching anything: infra_secrets.yml was listed LAST in 10 plays, after services_config.yml, so removal would flip precedence if the two shared a key. They share none, and neither does services_config.yml with group_vars/all/main.yml, so the removal is provably inert. services_config.yml was the last one standing. It held four unrelated things: caddy_sites_dir - an identical copy of roles/caddy_site/defaults/. Deleted; the role default is now the only one. *.tailscale_hostname (x3) - a THIRD copy of each box's identity, which inventory.ini already holds as ansible_host. Deleted. Edge plays now read hostvars[''].ansible_host - verified an edge play resolves that with nothing loaded and the other host in no play. Three copies of one name is how bitcoin_rpc_host ended up labelled "knots_box" while pointing at fulcrum-box. subdomains, ntfy topic, - genuinely global: their readers span managed, headscale namespace monitoring, vpn_control and edge, so no single group covers them. Moved to group_vars/all/main.yml where they auto-load. The ntfy_topic and headscale_namespace indirection through service_settings collapses to the global name. the four cross-host ports - the only entries with a real justification. Left in place; they move in the next commit. Also dead, all Uptime Kuma residue or duplication: phoenixd_monitor_name, forgejo_runner healthcheck_timeout_seconds/retries, fulcrum_tailscale_hostname, and bitcoin_knots_version - the last being a v-prefixed copy of bitcoin_knots_version_short that nothing read, two hand-maintained copies of one version string. Corrected a false comment: services_config.yml claimed the uptime_kuma subdomain "no longer resolves to anything". It resolves to 164.92.239.72 and answers HTTP 302, and 11 playbooks still template it. Same wrong premise as PLAN_3. Verification: all 37 playbooks' --list-tasks output is byte-identical before and after. A probe resolving all 22 values services_config.yml used to supply returns 21 identical and one intended deletion (caddy_sites_dir, now role-only - confirmed the role still resolves it: "Ensure Caddy sites-enabled directory exists" comes back ok against the real path). memos check-diff identical before and after. Syntax passes on every playbook.

A role default is invisible to that second play. But the shape was wrong in two ways. The file had to be named in vars_files: by 30 plays - opt-in configuration that someone will eventually forget - and five role defaults silently interpolated service_settings.*, so bitcoin_knots, fulcrum, datum_gateway and mempool were not self-contained: using any of them without that one vars_file entry broke it. Each port now lives in host_vars//main.yml: host_vars/knots_box_local/main.yml bitcoin_p2p_port, datum_gateway_api_port, datum_gateway_stratum_port host_vars/fulcrum_box_local/main.yml fulcrum_ssl_port host_vars/mempool_box_local/main.yml mempool_frontend_port host_vars auto-loads and outranks role defaults, so the owning role picks the value up with no vars_files at all, and the edge play reads the same single definition as hostvars[''].. The role defaults keep the protocol standard (8333, 50002, ...) so each role still works standalone, with the live deployment's value in host_vars winning. Also fixed a fourth copy of an inventory identity: the mempool Caddy play had "mempool-box:{{ ... }}" hardcoded in the upstream. It now derives the host from hostvars['mempool_box_local'].ansible_host, so inventory is the only place any box's name is written down. services_config.yml is deleted, with 25 more vars_files entries across 19 playbooks. Between this and the previous commit, 87 vars_files entries are gone and every variable in the repo now comes from group_vars/all, host_vars, inventory, a role default, or that service's own *_vars.yml. Verification: an edge-host probe resolves all eight ports and hostnames to byte-identical values to the ones services_config.yml used to supply. Each owning host resolves its own port through host_vars. All 37 playbooks' --list-tasks output is unchanged. The four edge plays that consume these values all check-diff changed=0 - the socket-proxy and Caddy units on vipy are byte-identical, which is the direct proof the rewiring landed on the same values. fulcrum and datum-gateway check-diff exactly as before (ok=28/changed=1 and ok=15/changed=1, both the known timer re-arm).

It is 25 import_playbook: lines and comments - no `hosts:`, no `roles:`. Which hosts get what stays on the `hosts:` line inside each playbook, exactly where it already was; nothing moved. Every role is already wrapped in a thin playbook carrying its own `hosts:` line, so there is no roles-vs-playbooks split to reconcile: from here everything is a playbook. What it buys: What runs on a host? ansible-playbook site.yml --limit --list-hosts Who gets thing Y? the `hosts:` line in Y's own playbook What is a host? ansible-inventory --graph Note --list-hosts, not --list-tasks: the latter prints every play regardless of --limit, so it will happily show you the bitcoin play under memos-box. Nine playbooks are deliberately excluded and the file names every one with a reason, so it accounts for all of them: the three infra/4xx monitoring plays (still assert on the removed Uptime Kuma credentials and fail immediately), 910_docker (says `hosts: managed`, but Docker is on 5 of 11 managed hosts and those 5 are exactly the ones that need it - running it installs Docker on the Bitcoin node and the hypervisor), two nodito one-shots, the Kuma notification setup, and two deliberate manual actions. Writing it surfaced an inventory collision. There is a HOST named `monitoring` in [vps] AND a group [monitoring], so Ansible warned and resolved `hosts: monitoring` to the host: [WARNING]: Found both group and host with same name: monitoring The group is renamed to [observability]; the host keeps its name. [caddy:children] and the two ntfy playbooks follow. Behaviour is unchanged - `hosts: monitoring` already resolved to the host - but the ambiguity is gone and the warning with it. Verified: inventory graph is warning-free, site.yml passes --syntax-check, and per-host play counts are identical before and after the rename.

Gatus runs on the new observability VPS, fronted by Caddy at status.contrapeso.xyz. Deployed as the upstream container image, not built from source. The role did build from source first - their Dockerfile is a bare `CGO_ENABLED=0 go build`, the Vue dashboard is compiled in via `//go:embed static` in web/static.go, and CGO can stay off because the sqlite driver is pure-Go modernc.org/sqlite - but that produces a binary upstream never ran, and it meant compiling the AWS SDK and gRPC on the smallest box in the estate. That load was heavy enough that unrelated Ansible tasks timed out while it ran. The cost of the container is a daemon on the machine whose job is to notice when everything else breaks; that trade is made deliberately and is written down in the role README. Pinned by DIGEST, not tag. A tag is mutable - v5.36.0 can be repushed - so pinning it alone is a weaker promise than it looks: gatus_image: "ghcr.io/twin/gatus@sha256:c5f210d0..." `docker compose pull` now either fetches exactly the reviewed image or fails. gatus_version is kept beside it only so a human can read the release; the two move together. The image is FROM scratch, so it has no /etc/passwd and its default user is root. The container runs as 10001:10001 with the host data dir owned to match, plus read_only, cap_drop ALL, and no-new-privileges. NET_RAW is added back only when gatus_allow_icmp, so the capability for icmp:// checks is a visible grant rather than something inherited from running as root. Config is a DIRECTORY, not a file. Gatus merges every *.yaml under GATUS_CONFIG_PATH - maps deep-merge, lists append - so the role owns 00-base.yaml (web, storage, ui, alerting, security) and each service will drop its own file into endpoints/, the same shape as caddy_site. A primitive defined twice is ambiguous and upstream refuses it, so anything that is not a list lives in the base file and nowhere else. Two bugs the deploy caught: * Gatus panics on a config with no endpoints ("configuration should contain at least one endpoint or suite"), so "install now, add endpoints later" is not a valid state. The role ships endpoints/00-self.yaml checking its own /health. Less circular than it looks: it proves the directory merged, the listener serves, and storage accepted a write. * web.address was carried over from the systemd design as 127.0.0.1. Inside a container that is the CONTAINER's loopback, which docker-proxy cannot reach - gatus came up healthy, self-check passing, while every connection to the published port was refused. It now always binds 0.0.0.0 inside the container; the isolation comes from publishing to 127.0.0.1 on the host. Auth is done at the edge, NOT with Gatus's own security.basic. Reading api/api.go, that middleware protects exactly four routes - the statuses endpoints. Everything else is registered on the unprotected router, including /api/v1/config, every badge, and /api/v1/endpoints/:key/uptimes/:duration and .../response-times/:duration/history, which return real data to anyone who can guess a key ("_"). Verified against the live instance: all seven routes returned 200 unauthenticated, and /uptimes/24h returned "1.000000". So the vhost uses caddy_site_body with a path carve-out rather than caddy_site_basic_auth, which has no way to exempt a path. The external-endpoint push API must NOT sit behind basic auth: it authenticates with `Authorization: Bearer `, and basic auth wants the same header. It is not unauthenticated - the handler 401s on a missing prefix, an empty token, or a token that does not match that endpoint's own. Verified end to end. All seven previously-open routes now 401. The push path distinguishes cleanly: POST with no auth gets Gatus's own "invalid Authorization header" with NO WWW-Authenticate; POST with a bogus Bearer gets 404 (key looked up, no external endpoints yet); GET on the same path gets Caddy's 401 with WWW-Authenticate: Basic, so the exemption is scoped to POST alone. The self-check still passes because it polls localhost inside the container and never traverses Caddy. The host itself was rebuilt from scratch: 01 (ok=9 changed=8), 02 (ok=12 changed=6), 910_docker (--limit, since that playbook still wrongly claims all of `managed` needs Docker), caddy (ok=13 changed=8), gatus (ok=18 changed=2). Not done here: gatus_alerting is still {} - valid, and every condition is evaluated and recorded, there is just nowhere to shout until a provider is chosen to replace ntfy.

**as the upstream container image**, on the +`observability` group. + +## Why the container + +Upstream publishes **no binary release assets**. The image is the only artefact +they ship and therefore the only one they test, so it is what `docker run` in +their README gets you, and it is what this role deploys. + +Building from source is entirely possible — their Dockerfile is a bare +`CGO_ENABLED=0 go build`, the Vue dashboard is compiled in via `//go:embed +static` in `web/static.go`, and the sqlite driver is pure-Go +`modernc.org/sqlite` so nothing needs linking. This role did that at first. The +reasons it doesn't now: + +- It produces a binary upstream never ran. +- It means compiling the AWS SDK, gRPC and the Google API libraries on the + smallest box in the estate. On this VPS that load was heavy enough that + unrelated Ansible tasks timed out while it ran. + +The cost of the container is a daemon on the machine whose job is to notice +when everything else breaks. That is a real trade, made deliberately. + +## Pinned by digest, not by tag + +```yaml +gatus_image_digest: "sha256:c5f210d0…" +gatus_image: "ghcr.io/twin/gatus@{{ gatus_image_digest }}" +``` + +A tag is mutable — `v5.36.0` can be repushed — so pinning the tag alone is a +weaker promise than it looks. The digest is a content address: if it resolves, +it is byte-for-byte the image reviewed here, and `docker compose pull` either +fetches exactly that or fails. `gatus_version` is kept alongside it purely so a +human can read which release it is; **the two must be updated together.** + +## What `FROM scratch` means for running it + +The image has no `/etc/passwd`, so there is no user to drop to by name and the +default is root. The compose file runs it by numeric id (`10001:10001`) and the +data directory on the host is owned to match. Everything else is locked down to +approximate what the systemd unit used to do natively: + +| systemd | compose | +|---|---| +| `ProtectSystem=strict` | `read_only: true` | +| `NoNewPrivileges=true` | `security_opt: [no-new-privileges:true]` | +| `CapabilityBoundingSet=` | `cap_drop: [ALL]` | +| `AmbientCapabilities=CAP_NET_RAW` | `cap_add: [NET_RAW]` (for `icmp://`) | + +## Configuration is a directory, not a file + +`GATUS_CONFIG_PATH` points at `/opt/gatus/config`, and Gatus merges every `*.yaml` +underneath it — maps deep-merge, lists append. This role owns exactly one file: + +``` +/opt/gatus/config/00-base.yaml web, storage, ui, alerting, security (this role) +/opt/gatus/config/endpoints/*.yaml one file per service (gatus_endpoint) +``` + +**A primitive defined in two files is ambiguous and upstream refuses it.** So +anything that is not a list belongs in `00-base.yaml` and nowhere else. Endpoints +are lists, so each service's file appends cleanly — the same shape as +`caddy_site`, where each service contributes its own vhost. + +## Pull and push + +Gatus polls. For anything with a reachable HTTP or TCP surface that is the +better check, because it tests the path a user actually takes. The monitoring +host joins the headscale mesh via `infra/920`, so internal boxes are reachable +by MagicDNS name and can be polled directly rather than having to report in. + +For state with no pollable surface — ZFS pool health, UPS mains status, disk +usage, backup freshness — Gatus has **external endpoints**, a push API: + +``` +POST /api/v1/endpoints/{group}_{name}/external?success=true&error=&duration= +Authorization: Bearer +``` + +with `heartbeat.interval` to alert when nothing reports in. That is the same +shape as the generic `healthcheck_push_url` already wired into every service +role, so those scripts need a URL, a POST, and an auth header — not a rewrite. + +## Variables + +See `defaults/main.yml`. The ones that matter: + +| Variable | Default | Note | +|---|---|---| +| `gatus_version` / `gatus_image_digest` | `v5.36.0` / `sha256:c5f210d0…` | must move together | +| `gatus_bind_address` | `127.0.0.1` | **never bind publicly** — the push API shares this listener | +| `gatus_storage_type` | `sqlite` | `memory` loses all history on restart | +| `gatus_alerting` | `{}` | pass-through; any provider Gatus supports | +| `gatus_allow_icmp` | `true` | adds back `NET_RAW` for `icmp://` checks | + +`gatus_alerting` empty is valid and is the current state: every condition is +still evaluated and recorded, there is just nowhere to shout yet. + +## Verifying + +```bash +docker ps --filter name=gatus +docker logs gatus --tail 50 +curl -s localhost:8080/health +ls /opt/gatus/config/endpoints/ +``` diff --git a/ansible/roles/gatus/defaults/main.yml b/ansible/roles/gatus/defaults/main.yml new file mode 100644 index 0000000..95c41ae --- /dev/null +++ b/ansible/roles/gatus/defaults/main.yml @@ -0,0 +1,83 @@ +--- +# Gatus, deployed the way upstream distributes it: the container image. +# +# Upstream publishes NO binary release assets - the image is the only artefact +# they ship, and therefore the only artefact they test.

Gatus merges every *.yaml there and appends lists, so callers compose without coordinating. roles/healthcheck runs on the monitored host: a check script, a systemd service, a timer, and an optional push. Ships a library of check bodies under templates/checks/. Everything PUSHES. Gatus never reaches out, which matters because nodito and its VMs are behind NAT, and because four of the five checks are internal state with no pollable surface at all. Liveness pushes too, deliberately: a heartbeat proves the host is running AND can reach the internet, where an ICMP probe from one vantage point only proves it answers pings from there. And since Gatus alerts when a heartbeat window expires, a check that stops running raises the alarm by itself - a dead timer looks exactly like a dead host, which is the correct reading. One bearer token per host, generated straight into the vault and never printed. A token only writes results for its own host's endpoints, so a compromised host can lie about itself, which it could do anyway. Three things learned from the source that shaped this: * Gatus polls its own config every 30s and reloads (main.listenToConfigurationFileChanges), so gatus_endpoint needs no restart handler - writing the file IS the deploy. * ...but on a reload it panics if the new config fails to parse, unless skip-invalid-config-update is set. Endpoint files are contributed by other playbooks, so one malformed file would take the monitor down at the worst possible moment. Now set. * The push URL uses a key Gatus computes, not the name you write: sanitize(group) + "_" + sanitize(name), lowercased with / _ . , space # + & replaced by "-" (config/key/key.go). So knots_box_local is knots-box-local in the URL. The playbook derives it rather than hand-writing. storage: maximum-number-of-results 900, up from upstream's 100. Gatus bounds the database by COUNT and trims inline on insert, so there is no retention job and no way to fill a disk - but history depth is then a function of check frequency, and 100 results at a 5-minute interval is 8 hours. 900 is ~3 days of liveness and ~2.5 years of the daily disk check. The uptime table is separate and its 30-day retention is hard-coded upstream. A bug worth recording: the first deploy shipped five scripts that all died with "syntax error: unexpected end of file". Jinja strips an included template's trailing newline and trim_blocks then eats the newline after {% endif %}, so the closing brace of check() landed on the same line as the body's last statement - `return 0}`. Every check was broken and the deploy still reported failed=0, because the role's "run once" task has failed_when: false and reports the result as a debug message nobody read. The blank line that fixes it is now load-bearing and commented as such. Verified by triggering every unit by hand rather than waiting on timers: all checks exit 0 on all hosts, and Gatus shows 26 UP / 1 DOWN. The one DOWN is liveness_watchtower, which is honest - that host currently refuses SSH (TCP connects, no banner exchange) and is excluded from this deploy. It is also the box still running Uptime Kuma. Known waste, not yet fixed: healthcheck installs its dependencies per CHECK rather than per HOST, so apt runs 29 times estate-wide for a curl that is already present, and daemon_reload runs 4x per host.

What the source side adds is LATENCY and DIAGNOSIS: the store only learns at the next 04:00 pull, and it cannot tell you whether the dump broke or the pull did. pull-job is separate from the per-source checks because it is a LEADING indicator where those are lagging ones. A disabled pull timer, a failed pull job, or a filling disk are all visible immediately, while the per-source checks only fire once an artefact is >26h stale - about a day later. Disable the timer at 10:00 and every source stays green until tomorrow; pull-job goes red this morning and names the cause instead of showing six stale sources. Frequencies: dumps 02:00-02:30 staggered, pull 04:00, verification 05:30, all daily and Persistent. 26h staleness decides red; a 30h Gatus heartbeat catches the verification itself having stopped, so a dead check-backups.timer cannot hide a stale backup. arbret has no dump endpoint: prd-arbret is in [arbret], which `managed` deliberately excludes, so nothing of ours runs there. Store-checked only. check-backups.sh was manual-only; it now runs on a timer and reports per source rather than only printing. The human-readable report is unchanged. A SERIOUS bug introduced and fixed in this change, recorded because the shape is easy to repeat: the reporting hook was added to backup.sh as a second `trap ... EXIT`. Bash REPLACES the EXIT handler rather than adding to it, so that silently deleted the trap which restarts the stopped service - the one the script's own comment calls "the point", and the bug the role was written to eliminate. Every backup then stopped its service and left it stopped. It took forgejo, lnbits, headscale and memos down for several minutes each, and nothing caught it: the dumps exit 0, the artefacts are correct, the deploy reports failed=0, and liveness only proves the HOST is up. There is now ONE EXIT handler doing both jobs, armed BEFORE the stop so a failure during the stop still restarts. Verified by rendering both variants, asserting exactly one EXIT trap in each, and simulating a mid-way failure to confirm the restart fires. Verified: all 12 endpoints UP; six sources pulled cleanly (arbret 31M, headscale 198K, memos 7.8M, vaultwarden 2.1M, lnbits 30M, forgejo 2.6G), store 16% full, "RESULT: all checks passed". Known gaps, deliberately not closed here: * `yell` warnings - disk 75-90%, an artefact under half the previous size, retention not pruning - never reach Gatus, because a push is binary. * Nothing verifies a backed-up service came back UP. That is the gap that let the trap bug run unnoticed, and it is what the next change addresses.

This closes the gap that let a real bug run unnoticed earlier today: a backup script left forgejo, lnbits, headscale and memos stopped, and NOTHING caught it. The dumps exited 0, the artefacts were correct, the deploy said failed=0, and liveness only proves the HOST is up - not that anything on it serves. One endpoint PER UNIT but only ONE timer per host: the check iterates that host's units and pushes a result for each, the way check-backups.sh reports per source. Four units on vipy would otherwise mean four scripts, services and timers. A single host-level red light would also say "something on vipy is down" without saying which, which is not the question anyone has. Keys are host-qualified because unit names collide - caddy runs on four machines. Which units a host runs lives in host_vars//monitored_services, because "what runs here" is a property of the machine, the same reasoning as the cross-host ports. nut-driver-enumerator is deliberately excluded: it is a oneshot generator that is `enabled` but always `inactive`, so it would report down forever. Checked live before excluding it. ── domain, DNS and public endpoints (infra/402) ──────────────────────────── The first checks that PULL rather than push, and that is the right way round: all three are about how the outside world sees us, so they must be measured from outside. Nothing is installed anywhere - no script, no timer, no token. They also have no heartbeat, because a heartbeat answers "did the reporter report"; when Gatus does the checking itself, failure is immediate. domain 1 endpoint, 24h, [DOMAIN_EXPIRATION] > 336h (two weeks) dns 11 endpoints, 24h, [DNS_RCODE] == NOERROR and [BODY] == the IP public 14 endpoints, 5m, 11 HTTPS + 3 TCP Expected A records are derived from inventory (hostvars[host].ansible_host), not written down again. The estate's recurring bug is an address recorded in a second place and left behind when the machine moved; asserting against inventory means a renumbered box is one edit, not two. Expected HTTP status was checked live per site rather than assumed. Two return 401 - the Gatus dashboard and the DATUM dashboard, both behind basic auth - and that is what is asserted: expecting 200 there would go green precisely when the auth broke. headscale asserts /health rather than /, which is a 404 by design. Every HTTPS check also carries [CERTIFICATE_EXPIRATION] > 168h, which is free on an endpoint already being polled and catches a renewal that silently stops. Two things learned the hard way, both now in comments: * A domain-expiry endpoint needs a URL SCHEME. Gatus derives the endpoint type from the prefix (endpoint.Type()), so a bare "contrapeso.xyz" is UNKNOWN and the whole config is rejected. It is https:// plus a DOMAIN_EXPIRATION condition and no status assertion, so the registrar's parking page at the apex is irrelevant. Upstream also enforces a 5m minimum interval for that placeholder, because it uses a free whois service. * That rejection proved skip-invalid-config-update was worth adding. Gatus logged "the configuration file was updated, but it is not valid, the old configuration will continue being used" and kept running. Without it the reload path calls panic() and one malformed contributed file takes the monitor down. Verified: 15/15 service endpoints UP; 26/27 public-facing UP. The single DOWN is public_memos, correctly - memos-box is powered off, and the condition result reads [STATUS] (502) == 200. memos-box and arbret-staging-box were shut down deliberately from the Proxmox UI to test the liveness endpoints; their endpoints stay registered and will go green when the VMs return.

Both domains checked daily with two weeks of runway, because registration renewal is a manual act at the registrar and losing a domain is not recoverable the way losing a host is.

The old system_healthcheck.sh only computed uptime and pushed, which is exactly a liveness heartbeat. The old disk monitor was WEAKER than its replacement: it checked "/" alone at 80%, where the new one walks every real filesystem at 85%. Deleting the playbooks was not the hard part. The units they installed live on the hosts, enabled, and keep firing regardless of what the repo says - two of them were still pushing to uptime.contrapeso.xyz every 15 minutes across nine machines. A playbook deleted without a cleanup leaves its output running forever with nothing left to explain it. So infra/409_remove_legacy_monitoring stops, disables and removes the units, deletes /opt/{disk-monitoring, system-healthcheck,nodito-monitoring,zfs-monitoring}, and removes the orphaned hand-written ups-heartbeat.sh. It ends by grepping for any surviving Kuma reference and reporting it. Kept permanently and idempotent, so a rebuilt or restored host cannot quietly bring them back. A trap avoided: the monthly ZFS scrub lived INSIDE 32_zfs play 2. Deleting the play wholesale would have silently stopped scrubbing the pool - and an unscrubbed pool makes the health check meaningless, because it would have nothing true to report. That play is now scrub-only and check-runs ok=5 changed=0. ZFS pool capacity added as a sixth condition to the zfs-health check. `zpool status` reports a 95% full pool as perfectly ONLINE, so capacity has to be read separately with `zpool list` - and it is the failure you get warning of rather than the one you discover. Threshold 80%, because ZFS allocation degrades badly past roughly that and fragmentation is hard to undo. The pool is at 47%. Verified both directions: passes on the real pool, and a simulated 91% exits 1. Also fixed the waste recorded in c2de6db: the healthcheck role installed its dependencies once per CHECK rather than per HOST - 29 apt transactions estate-wide for a curl already present, and the slowest part of every deploy. It now deduplicates within a play run, and the redundant standalone daemon_reload is gone (the systemd task already does one). site.yml updated, which exposed that services/gatus was never in it. It now runs before the three registration playbooks, since registering endpoints against a Gatus that is not yet serving would simply fail. Verified: no legacy timer remains on any host; 83 endpoints, 83 UP, 0 DOWN.

It is a HANDLER, so every memos config change since 2026-09-11 applied to disk and silently never restarted the service. Ungated. That is the same failure found in forgejo-runner's self-assert, phoenixd's timer enable, mempool's three timer enables, fulcrum's restart handler and bitcoind's restart handler. Every guard was read and asked "monitoring or deployment?" before being deleted, which is the only reason this was caught. ── What was removed ──────────────────────────────────────────────────────── 30 uptime_kuma_enabled guards across 7 unconverted service playbooks, and the 29 Kuma monitor-creation tasks they gated (embedded Python that drove the Kuma API, temp credential files, cleanup) 7 dead uptime_kuma_api_url definitions 7 stale DEPRECATED banners uptime_kuma_enabled and subdomains.uptime_kuma from group_vars/all healthcheck_push_urls from the vault - 30 push tokens services/ntfy/setup_ntfy_uptime_kuma_notification.yml -> archive/ The explanatory comments in the six converted roles are KEPT on purpose. They record why a handler is ungated, and deleting the explanation invites someone to helpfully re-add the guard. ── The probes moved rather than died ─────────────────────────────────────── Eight per-service health checks were still pushing to Kuma. They are not superseded by infra/401: that answers "is the unit running", these answer "does the service actually respond" - an RPC call to bitcoind, a TCP connect to Fulcrum's Electrum port, an HTTP fetch from Mempool's backend. A process can be perfectly `active` and useless. So they were repointed, not deleted. Gatus external endpoints take a POST with a bearer token and success=true|false where Kuma took a GET with ?status=up, so report() now maps up/down to true/false internally and no call site changed. Registered by infra/403 as the `probe` group, one token per host. Two bugs fixed while in there: * forgejo-runner's check only ever reported SUCCESS - it exited before pushing when the runner was down, so a failure was invisible until the heartbeat window expired. Reporting the failure is the entire point of a check. * All six healthcheck .service units were mode 0644 and now carry a bearer token. They are 0600. Verified: 91 endpoints, 91 UP, 0 DOWN. Every probe triggered by hand and confirmed arriving. Zero Kuma URLs left in the vault, zero live references in any playbook or role. Still standing, deliberately: the Kuma container on watchtower, its Caddy vhost, and the uptime.contrapeso.xyz DNS record. Turning the service off is a separate decision from removing the code that talked to it.

Removed from [vps], with its host_vars, its push token, and the six Gatus endpoints that referenced it (liveness, disk, two systemd services, the ntfy DNS record and the ntfy HTTP check). ntfy went with it - it ran nowhere else - so services/ntfy is deleted, subdomains.ntfy and ntfy_topic are gone from group_vars, and the ntfy playbook is out of site.yml. ntfy_topic already had no readers: the three infra/4xx plays that used it were deleted when their checks were superseded. Two things this exposed. services/ntfy/deploy_ntfy_playbook.yml was pointing at the WRONG MACHINE. It said `hosts: observability`, which resolves to the host `monitoring` (64.226.70.190) - but ntfy ran on watchtower, and ntfy.contrapeso.xyz pointed there. Running it would have installed ntfy on the new VPS. Moot now, but it is the same stale-identity failure as the rest: the group meant watchtower when the play was written, and nobody revisited it when the group changed. Watchtower was in [vps] and NO role group at all, while running caddy, ntfy and Uptime Kuma - nothing in the repo managed any of it. More seriously: ntfy-emergency-app on vipy (avisame.contrapeso.xyz) sends its notifications to https://ntfy.contrapeso.xyz, topic "emergencia". Destroying watchtower breaks it, and it is an EMERGENCY notifier - it would fail silently at exactly the moment it matters. That is NOT resolved here, deliberately: standing ntfy up elsewhere, pointing at ntfy.sh, or retiring the app are all decisions, not cleanups. What this change does is make the break impossible to miss. The URL was derived from subdomains.ntfy, so deleting that would have turned it into an undefined variable buried in a template. It is now an explicit ntfy_service_url in the app's own vars, still holding the old value, with the three options written above it. The ntfy credentials stay in the vault because that app still needs them - the vault was restored from HEAD and only watchtower's push token removed, rather than re-handling the plaintext. Verified: no reference to watchtower or its IP anywhere in the repo; Gatus down from 91 to 85 endpoints, 85 UP, 0 DOWN.

And a window can only ever be as tight as the push frequency - which is why two checks moved rather than just having their numbers changed. liveness, cpu, ups, service-health, probes 16m -> 11m disk, zfs daily/30h -> 6-hourly/7h backup store + pull job daily/30h -> 6-hourly/7h DNS records 24h -> 6h backup dump 30h -> 26h backup-dump stays slow because the dump genuinely is daily. The store-side check catches the same fault within 6h by reading the source's dump timestamp out of the artefact filename, so 26h is a backstop rather than the primary signal. ── Thresholds differ by check type, deliberately ─────────────────────────── `failure-threshold` counts consecutive failures, but "consecutive" is a different amount of wall-clock time per check: a push endpoint produces one failure per heartbeat window, a pulled one per interval. The default of 3 would mean 33 minutes on an 11m heartbeat and over a day on a 7h one. More importantly the heartbeat window ALREADY encodes the tolerance - an 11m window on a 5-minute push is exactly "one missed push forgiven" - so stacking a threshold of 3 triples a tolerance that was already chosen. Hence: push/heartbeat endpoints failure-threshold 1 pulled, 5m (public) failure-threshold 3 (= 15 minutes) pulled, 6h/24h (dns, domain) failure-threshold 1 ── The Signal transport ──────────────────────────────────────────────────── roles/signal_api runs signal-cli-rest-api on the observability host, pinned by digest, MODE=native. It publishes NO PORTS. The API has no authentication of any kind - anything that reaches it can send messages as you and read your Signal. Gatus talks to it over a shared docker network by service name, which is also WHY the network exists: Gatus runs in a container, so the host's loopback is unreachable from it and a port published on 127.0.0.1 would not have worked. MODE=native and not json-rpc because this VPS has 464MB of RAM and already runs Gatus and Caddy. The json-rpc modes hold a resident JVM; native runs a binary per request, and alerts are rare enough that startup cost per alert is the right trade. Monitored - Gatus polls /v1/health over the same network path the alerts take, so it proves the delivery route rather than mere container liveness. Deliberately NOT backed up: the data directory holds Signal private keys and the recovery path is to link the device again from the phone. Neither the signal-api endpoint nor Gatus's self-check carries a Signal alert. If either is down, Signal is precisely what cannot deliver the alert. ── Four traps hit while linking, all now in the role README ──────────────── * /v1/qrcodelink is BROKEN in native mode - returns "no data to encode" while the binary itself emits a perfectly good URI. Not worked around by switching MODE, which would put a JVM in the path of every alert permanently. * The data dir must be owned by uid 1000, not root. A root-owned 0700 dir cannot be traversed by the container user, so linking silently never completes and /v1/accounts returns "Failed to read local accounts list". * `docker exec` runs as ROOT while the service runs as uid 1000, so without --config the account is written to /root/... on the container's ephemeral layer. It reports success and is destroyed on the next recreate. * The phone reporting "network error" was IPv6: chat.signal.org resolves to dualstack AAAA records first, the container has no IPv6 address, and this host's IPv6 path is broken - the same edge that 404'd the Go tarball. Fixed with a mounted gai.conf that prefers IPv4. Verified: provider loads (configuredProviders=[signal]), a test message was delivered and confirmed received, 84 endpoints carry alerts, 86 UP / 0 DOWN.

All six hide-* options (hide-hostname, hide-url, hide-port, hide-conditions, hide-errors, and dont-resolve-failed-conditions) already default to false upstream, so hostname, URL, port, conditions and errors were all being shown. The one setting that genuinely displays MORE is resolve-successful-conditions. By default a FAILING check resolves its placeholders - "[STATUS] (502) == 200" - while a PASSING one drops the value and shows only "[STATUS] == 200". With it on, a healthy DNS check now reads: [DNS_RCODE] (NOERROR) == NOERROR [BODY] (64.226.70.190) == 64.226.70.190 which says what it actually resolved to rather than merely that the assertion held. Applied to all 27 pulled endpoints via a gatus_endpoint_default_ui that each caller can override. It applies to pulled endpoints ONLY: an external (push) endpoint has no `ui` field upstream at all, because it carries no conditions - success comes from the push. The template was initially emitting the block in both loops; emitting an unknown key into the external-endpoints list risks a parse rejection, and a rejected config is exactly what skip-invalid-config-update exists to survive. Also made the page-level `ui` a pass-through dict, the same shape as gatus_alerting, so every upstream option (description, dashboard-heading, logo, link, favicon, buttons, custom-css, dark-mode, default-sort-by, default-filter-by) is reachable without a variable per key. Replaces the two one-off gatus_ui_title / gatus_ui_header variables. Set default-sort-by: group, because the dashboard's own grouping toggle starts OFF and remembers per browser in localStorage - without it the ten groups render as one flat list of 86 rows for anyone who has not clicked it. Note the limit of all this: it is configuration. Layout, card design and group rendering come from the Vue app compiled into the binary (//go:embed static), so changing those means forking and rebuilding the image - which would discard the pinned-digest property the deployment relies on.

Fix it, and the false DOWNs it hid behind MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Investigating a dashboard full of DOWN services that were plainly healthy turned up three bugs, all introduced by me. ── 1. The disk check has been lying since it was written ─────────────────── df: options -P and --output are mutually exclusive `df -P ... --output=pcent,target` errors out. `2>/dev/null` swallowed it, the read loop got nothing, `worst` stayed 0, and the check reported "max 0% on /" and exited 0 on EVERY host regardless of real usage. vipy is at 58%. It would never have caught a full disk - a green light wired to nothing, which is worse than no check at all. Dropped -P. More importantly, "df returned no filesystems" is now a FAILURE rather than being read as 0% - the original bug was only invisible because an empty result was indistinguishable from an empty disk. Testing the fix immediately surfaced a second problem it had been masking: /sys/firmware/efi/efivars sits at 87% on a healthy machine, so a working check would have paged daily. efivarfs and ramfs join tmpfs/devtmpfs/squashfs/overlay in the exclusions, all of them pseudo-filesystems whose "usage" is not a fact an operator can act on. It now reports "max 73% on / (3 filesystems)". ── 2. The false DOWNs were a half-finished deploy ────────────────────────── The previous commit tightened heartbeats from 30h to 7h AND moved the checks from daily to 6-hourly - but only the registration side was deployed, with --limit observability. The hosts kept pushing once a day against a 7h window, so after seven hours every disk, ZFS and backup-store endpoint went red. Nothing was wrong with the services and nothing was wrong with Gatus: it correctly reported that pushes were not arriving. Changing a heartbeat window without deploying the matching cadence is a guaranteed false alarm, and the two have to ship together. ── 3. The new OnCalendar was invalid ─────────────────────────────────────── "*-*-* 05:30:00,11:30:00,17:30:00,23:30:00" is not valid systemd syntax - a comma-separated list of FULL TIMES is rejected with "bad unit file setting", and the timer silently failed to install. Corrected to "*-*-* 05/6:30:00" and validated with `systemd-analyze calendar` before deploying, which is how this should have been written in the first place. Verified: 11 disk checks and the ZFS check all HEALTHY on a manual run; timers confirmed on the hosts as 00/6:00:00, 00/6:20:00 and 05/6:30:00; 86 UP / 0 DOWN.

Put it in git `Create ACL policies file` wrote this, verbatim, to /etc/headscale/acl.json: content: | {} An empty policy. The real rules - who may reach which host on which port - were maintained by hand on spacey and existed nowhere else. So the repo and the box disagreed about the single file that governs every machine's access to every other machine, and the repo's version was "nothing is allowed". It had already fired once. /etc/headscale/acl.json.937464.2026-09-12@14:03:08~ is Ansible's own backup of a 1596-byte policy it replaced with {} on 12 Sep; the live file is dated 17 Sep, so somebody rebuilt it by hand afterwards without the playbook ever being corrected. Every subsequent `site.yml` run was one command away from flattening the whole tailnet's access rules again. This commit changes nothing on spacey. The policy now lives in templates/acl.json.j2, captured verbatim from the live file, and the task is a `template:` instead of an inline `{}`. Rendering it produces sha256 1ed14e7247d957db5e9f8d4f4c53846dc646131ad900054c868483a9a84ed8fd, byte for byte the file that was already there - verified before applying, and again after. Three deliberate choices: - A template file, not the inline `content:` used elsewhere in this playbook. The whole failure was three invisible characters passing review; a 2KB policy needs to show up as a diff. - `validate: python3 -m json.tool %s`. headscale refuses to load a malformed policy, and a policy it will not load is the same outage as an empty one. - `"counter-net@"` is now `"{{ headscale_namespace }}@"`, which is already a fact in group_vars/all/main.yml rather than a fourteenth hand-typed copy. The header comment records why a node with no ACL rule is INVISIBLE rather than merely unreachable - it never appears in `tailscale status`, MagicDNS does not resolve it, and the symptom is a downstream "no such host" that looks like a DNS problem. That cost an hour today.

Syncing at 24% as of this commit, 0 restarts, 0 OOM kills. ── The build-from-source requirement could not be met ────────────────────── The intent was to build it ourselves and check the result against the published checksums. That is not achievable for this release, and the role's README says so at length so nobody re-derives it: contrib/guix - the reproducible build that yields a byte-identical tarball - exists ONLY on monero master. At tag v0.18.5.1 contrib/ contains `gitian`, whose README wants an Ubuntu 18.04 host (EOL 2023) and python-cheetah. A plain `make release-static` is not reproducible at all, so it produces a binary whose hash matches nothing - failing both halves of the ask. So we install the published binary and prove its provenance instead: 1. binaryFate's key is VENDORED at files/binaryfate.asc. A trust root fetched over the network at the moment you need it is not a trust root. Its fingerprint is asserted after import regardless. 2. hashes.txt is verified, and the assertion is on gpg's `VALIDSIG ` status line - NOT on the string "Good signature", which is what bitcoin_knots greps for and which passes for any key in the keyring. 3. The hash is looked up in the output of `gpg --decrypt`, not in the raw clearsigned file, so nothing unsigned is ever searched. 4. The lookup requires hash AND filename on one line. Tested with a positive and a negative control before deploying: the real tarball matches, a corrupted hash correctly fails. monero_sha256 in defaults/ is a second in-git assertion so a version bump cannot happen without the checksum moving in the same diff. When v0.19 ships with guix on the release branch this gets easier, and the README records why: the published monero-linux-x64 tarball unpacks to monero-x86_64-linux-gnu-v0.18.5.1/, i.e. it IS the guix DISTNAME renamed, so sha256(guix output) will equal the hashes.txt entry exactly. ── The 500 GB disk is provisioned in code ────────────────────────────────── knots-box mounts /mnt/knots_data (~875 GB of chain) entirely by hand; that mount appears nowhere in Ansible and a rebuild of that host would come up with the blockchain silently missing. tasks/storage.yml does not repeat it. Whole device, no partition table. Everything after mkfs goes by UUID, because /dev/sdX is assigned by the kernel at boot and this estate has been bitten eight times by an identifier written down once whose thing then moved. monero_data_device is used ONLY to create the filesystem. Guards refuse to touch the root disk or to overwrite an unrecognised filesystem, and a final assert confirms the data directory is not still on /. fstab gets `nofail` so a missing disk cannot drop a headless VM into an emergency shell - and the unit gets `RequiresMountsFor=`, without which monerod would then start, find an empty directory, and write a 300 GB chain onto a 10 GB root disk. With it the unit refuses to start and infra/401 says so within five minutes. The mount-point task and the ownership task deliberately share owner and mode. Writing the obvious root:root 0755 on the first made them disagree and every run flipped the directory back and forth; caught by re-running --check. ── Exposure: one HTTPS vhost, zero new open ports ────────────────────────── Two RPC servers, not one: unrestricted on 127.0.0.1:18081 for administration and the health check, restricted on :18089 for everything else. That is `rpc-restricted-bind-port` and deliberately NOT `restricted-rpc=1`, which would restrict the loopback server too. Verified live: the restricted port reports restricted=true and blanks version and start_time. --rpc-login is HTTP Digest (contrib/epee/src/http_auth.cpp) and core_rpc_server::init hands the same login to both servers. Caddy on vipy does TLS and routing only - no caddy_site_basic_auth, because a Basic challenge would collide with the Digest challenge Feather answers. Verified end to end from the WAN: 401 unauthenticated, get_block_count over /json_rpc when authenticated, 401 again with a wrong password. No UFW rule, and that is correct: tailnet traffic bypasses UFW entirely because `-A INPUT -j ts-input` sits ahead of every ufw-* chain. Confirmed on mempool-box before relying on it here. P2P is outbound only. Nothing forwards 18080, so the node dials out, syncs and serves us without relaying for strangers; no-igd follows from that. ── Monitoring: infra, systemd, public. No backups ────────────────────────── Six Gatus endpoints, all green: liveness, disk, services/monerod-box-local/ monerod, probe/monerod, dns/monero.contrapeso.xyz, public/monero. The probe does NOT assert `synchronized`. A full sync takes days and a check requiring it would report DOWN for every one of them - an alarm with the batteries taken out. Height and sync state go in the message instead. The timer carries no `Requires=monerod.service`. Fulcrum's did, and sat active+enabled for seven months without firing once. public/monero asserts 401, not 200, so it goes red if rpc-login ever stops being enforced. No backups, deliberately, following the phoenixd precedent: the chain is re-syncable public data and there is no wallet on this node. ── Known constraint ──────────────────────────────────────────────────────── The VM has 2 GB and no swap; monerod's RSS is ~1.3 GB mid-sync. It is holding (0 OOM kills, ~1 GB available, kernel reclaiming cache) but 8 GB is the recommendation once the initial sync is done. out-peers/in-peers are held at 16/8 partly for this reason. Bumping it is a Proxmox resize plus memory_mb here, since the vm resource sets ignore_changes = all. The 500 GB data disk is likewise invisible to tofu - it was attached in the UI and the vm resource ignores it - so vms.auto.tfvars now carries a comment saying where it is and what mounts it.

That is not achievable for the current release, and it is +worth writing down why so nobody re-litigates it: + +- `contrib/guix`, the reproducible-build system that produces a byte-identical + tarball, **exists only on monero `master`**. At tag `v0.18.5.1` `contrib/` + contains `gitian`, not `guix`. +- Reproducing v0.18.5.1 therefore means **Gitian**, whose README requires an + Ubuntu 18.04 host (EOL 2023), LXC or Docker, and `python-cheetah` (Python 2). +- A plain `make release-static` is **not** reproducible. It would give us a + self-built binary whose hash matches nothing - not upstream's, not anyone + else's - so it satisfies neither half of "build it ourselves AND check the + checksum". + +So the role installs the published binary and proves its provenance instead. +That chain is real, and it is the strongest claim available for this release: + +1. binaryFate's public key is **vendored** at `files/binaryfate.asc`. A trust + root fetched over the network at the moment you need it is not a trust root. + Its fingerprint is asserted after import anyway + (`81AC591FE9C4B65C5806AFC3F0AF4D462A0BDF92`), so a swapped file is caught. +2. `hashes.txt` is downloaded and its clearsigned signature verified. The + assertion is on gpg's `VALIDSIG ` status line, **not** on the + string "Good signature" - `bitcoin_knots` greps for the latter, which passes + for *any* key in the keyring. +3. The verified plaintext is written out by `gpg --decrypt`, and the tarball's + SHA256 is looked up in *that*, not in the raw clearsigned file. +4. The lookup requires the hash **and** the filename on one line, so a hash + belonging to a different artefact cannot satisfy it. + +`monero_sha256` in `defaults/` is a second, in-git assertion passed to +`get_url`. It is not the security control - step 4 is - but it means a version +bump cannot happen without the checksum moving in the same diff. + +**Bumping the version: change `monero_version` and `monero_sha256` together.** + +### The forward path + +The published `monero-linux-x64-v0.18.5.1.tar.bz2` unpacks to +`monero-x86_64-linux-gnu-v0.18.5.1/` - that is the Guix `DISTNAME`, renamed at +publish time. So once v0.19 ships with Guix on the release branch, +`sha256(guix output) == hashes.txt entry` holds exactly, and a `guix` install +method can be added here without changing anything else. + +## The data disk + +The blockchain is on a **dedicated 500 GB disk** (`scsi1`), not on the 10 GB +root filesystem. `tasks/storage.yml` creates the filesystem and the fstab entry. + +This is done in code on purpose. `knots-box` mounts `/mnt/knots_data` (~875 GB +of chain) entirely by hand, and that mount appears nowhere in Ansible - a +rebuild of that host would come up with the chain silently missing. + +Three things there are load-bearing: + +- **The whole device, no partition table.** One disk, one job; a partition table + is just another layer that can disagree with itself. +- **Everything after mkfs goes by UUID.** `/dev/sdX` ordering is decided by the + kernel at boot. This estate has been bitten eight times by an identifier + written down once whose thing then moved; `monero_data_device` is used *only* + to create the filesystem. +- **`RequiresMountsFor=` in the unit.** `nofail` in fstab means a missing disk + does not drop a headless VM into an emergency shell - but without + `RequiresMountsFor` monerod would then start, find an empty directory, and + begin writing a ~300 GB chain onto a 10 GB root disk. With it, the unit + refuses to start and `infra/401` reports it within five minutes. + +The mount-point task and the post-mount ownership task deliberately use the +**same** owner and mode. Writing the obvious `root:root 0755` on the first made +the two disagree, and every run flipped the directory back and forth. + +## Exposure: one HTTPS vhost, no new open ports + +- **P2P is outbound only.** Nothing forwards 18080 to this box. The node dials + out, syncs fully and serves us; it just does not relay for strangers. + `no-igd=1` follows - with nothing forwarded there is nothing for UPnP to do + except announce us to the router. +- **Two RPC servers, not one.** + - unrestricted on `127.0.0.1:18081` - administration and the health check. + - restricted on `:18089` - the only surface anything off-box touches. + + This is `rpc-restricted-bind-port`, deliberately **not** `restricted-rpc=1`. + That flag restricts the loopback server too, and then we could not ask our own + node anything useful. Verified live: the restricted port reports + `restricted=true` and blanks `version` and `start_time`. +- **`rpc-login` is HTTP Digest** (`contrib/epee/src/http_auth.cpp`), and + `core_rpc_server::init` hands the same login to *both* servers. Both ports + answer an unauthenticated request with 401. +- **Caddy on the edge host terminates TLS and nothing else.** No + `caddy_site_basic_auth`: Caddy's Basic challenge would collide with the Digest + challenge Feather expects. monerod's own auth is the authentication. + +### No UFW rule, and that is correct + +Traffic arriving over the tailnet **bypasses UFW entirely**. Verified on +`mempool-box`: UFW is active with default-deny-incoming and `22/tcp` as its only +allow rule, yet the edge host reaches its frontend port - because +`iptables -S INPUT` puts `-A INPUT -j ts-input` ahead of every `ufw-*` chain. +Adding a UFW allow here would be cargo cult. + +## Monitoring + +Four Gatus endpoints, all verified passing: + +| Endpoint | Source | Answers | +|---|---|---| +| `liveness/monerod_box_local` | `infra/400` | is the host up | +| `disk/monerod_box_local` | `infra/400` | is it running out of space | +| `services/monerod-box-local/monerod` | `infra/401` via `monitored_services` | is the unit active | +| `probe/monerod` | this role + `infra/403` | does monerod actually answer RPC | + +**The probe deliberately does not check `synchronized`.** A full initial sync +takes days. A check requiring `synchronized: true` would report DOWN for every +one of those days, which is not a monitor - it is an alarm with the batteries +taken out. Answering RPC is the health question; height and sync state go in the +message so they are visible without being alertable. + +The timer carries **no `Requires=monerod.service`**. Requires on a timer stops +the timer when the watched unit stops - "if the thing I am watching goes down, +stop watching it" - and leaves nothing to re-arm it. Fulcrum's timer carried it +and sat `active`/`enabled` for seven months without firing once. `bitcoin_knots` +still carries it; do not copy that. + +`Enable and restart the monerod health check timer` reports `changed` on every +run. That is intentional and matches `datum_gateway`: `state: restarted` is how +a timer gets re-armed, and `started` is a no-op on an already-active timer. + +## Backups: none, deliberately + +The blockchain is re-syncable public data and there is no wallet on this node, +so a backup job would move hundreds of GB around to protect nothing. This +follows the `phoenixd` precedent (Plan 5, Model C) of recording an exclusion as +a decision rather than leaving it to look like an oversight. + +## Known constraint: RAM + +The VM has **2 GB and no swap**. Mid-sync, monerod's RSS was already 1,333 MiB +of 1,973 MiB with ~100 MiB free. No OOM kill has happened yet, but the working +set grows with the database and there is no swap to absorb a spike. `out-peers` +and `in-peers` are held down (16/8) partly for this reason. + +**8 GB is the recommendation.** Bumping it means editing `memory_mb` in +`tofu/nodito/vms.auto.tfvars` and resizing the VM in the Proxmox UI - the vm +resource sets `ignore_changes = all`, so tofu will not do it for you. diff --git a/ansible/roles/monero/defaults/main.yml b/ansible/roles/monero/defaults/main.yml new file mode 100644 index 0000000..633f3c0 --- /dev/null +++ b/ansible/roles/monero/defaults/main.yml @@ -0,0 +1,96 @@ +# Monero node (monerod) configuration variables. +# https://docs.getmonero.org/interacting/monerod-reference/ + +# --- Version and artefact --------------------------------------------------- +# Bump monero_version and monero_sha256 TOGETHER.

Ten Gatus endpoints green across the node and the explorer. ── It needs a compiled monero source tree, not a running monerod ─────────── xmrblocks is not an RPC client. cmake/FindMonero.cmake imports 21 STATIC libraries out of a monero build tree and includes its headers, because it opens the LMDB directly. The release tarball we install for the daemon ships only executables - no .a files, no headers - so there is nothing on the box to link against, and building it means compiling monero first. Measured on Debian 13, building only the libraries it links: peak RSS, one cc1plus ~3.2 GB peak RSS at -j4 ~5.5 GB wall time at -j4 167 s source + build tree 195 MB toolchain 1.6 GB That rules the box out at ANY parallelism: 768 MiB and 1800 MiB were both OOM-killed at -j1 and -j2, because a single translation unit over 3 GB is not something lower -j works around. My first estimate of "~10 GB of disk" was wrong by two orders of magnitude - that figure describes upstream's full `make`, which also builds monerod, both wallets and the test suite, none of it linked here. Disk was never the constraint. So scripts/build-xmrblocks.sh does the build in a debian:13 container. An artefact only one machine can produce is one nobody can audit; this way any host with Docker and ~6 GB reproduces it. It verifies the monero source against binaryFate's signature exactly as roles/monero does for the daemon, and the role asserts the resulting sha256 ON THE CONTROL NODE before copying a single byte. ── Three upstream problems, none documented anywhere ─────────────────────── Found by building, not by reading: 1. libasio-dev is absent from upstream's dependency list. That list is Ubuntu-based; Crow wants standalone asio.hpp, not boost/asio.hpp, and on Debian 13 the build dies outright. 2. The explorer does not compile against monero v0.18.5.1. v0.18.5.0 changed get_pruned_transaction_hash from returning the hash to returning bool with an out-param, and src/page.h still calls the old form. Upstream's Dockerfile pins v0.18.4.0, which is why nobody has hit it. Patched from an exact-line anchor, so if upstream fixes it the build STOPS rather than quietly doing something else. We patch instead of building against 0.18.4.0 because the signed hashes.txt only covers the current release - using the older source would mean dropping the provenance chain. LMDB is VERSION 5 in both, so either reads the other's database. 3. FindMonero.cmake hunts for miniupnpc inside the monero build tree with NO_DEFAULT_PATH, but monero stopped vendoring miniupnp as a submodule. Fixed with a cache override rather than patching their cmake. USE_DEVICE_TREZOR=OFF as well - an explorer has no use for hardware wallets and it drops the generated protobuf units. Verified that xmrblocks still links. ── Two things in the unit that look wrong and are not ────────────────────── WorkingDirectory is load-bearing: page.h hardcodes TMPL_DIR as "./templates", resolved relative to cwd at REQUEST time. Get it wrong and the service starts, binds 8081, and 500s every page. That is also why the health check fetches a real page and greps it instead of probing the port. ReadWritePaths must include the blockchain directory even though the database is opened read-only: monero sets mdb_flags = MDB_RDONLY WITHOUT MDB_NOLOCK, so LMDB still registers this reader in lock.mdb. With ProtectSystem=strict and nothing writable the open fails. "It only reads, so grant it nothing" is wrong. ── Timeouts are measured, not guessed ────────────────────────────────────── proxmox-tank-1 is a spinning-disk mirror and xmrblocks says so on startup. First start took 98s to open the LMDB before binding (wait_for now allows 300s), and a COLD index page took 68 SECONDS where the next two took 0.87s and 0.012s (the check now allows 90s, its unit 180s). The first pass used 90s and 25s and produced exactly the false failures you would expect. A stat() bug was caught the same way: `stat` computes a sha1 by default, so checking that data.mdb exists was hashing the entire 40 GB blockchain. --check found it before a real run did. ── Exposure ──────────────────────────────────────────────────────────────── Caddy on vipy terminates TLS; the upstream is reached over the tailnet, which needed a headscale ACL entry for tag:monerod-box:8081 - without it the node is invisible, not merely unreachable, and the symptom is a 502 "no such host". No authentication, deliberately: it is a block explorer over public chain data. That includes --enable-pusher, so a visitor can relay a raw transaction through our node. A choice, not an oversight; flip xmrblocks_enable_pusher to close it. ── Also ──────────────────────────────────────────────────────────────────── monerod-box raised 2048 -> 6144 MiB. Not for the explorer: monerod alone had outgrown 2 GB past ~39% of the chain and was OOM-killed twice in a morning at 1.74 GB anon-rss. Recorded in vms.auto.tfvars because ignore_changes = all means tofu will not reconcile it. The box now idles at ~1.2 GB of 5.9 GB with both services up. No backups, deliberately - binary, templates and chain are all reproducible.

This one cannot, and the reason is +worth recording so nobody "fixes" it later. + +`xmrblocks` is not a client of monerod. Its `cmake/FindMonero.cmake` imports 21 +**static libraries** out of a compiled monero source tree and its headers, because +it opens the LMDB directly rather than going through RPC. Building it therefore +means compiling monero first — and the release tarball we install for the daemon +contains only executables, no `.a` files and no headers, so there is nothing on +the box to link against. + +Measured on Debian 13, building only the libraries `xmrblocks` needs: + +| | | +|---|---| +| peak RSS, one `cc1plus` | **~3.2 GB** | +| peak RSS, `-j4` concurrent | **~5.5 GB** | +| wall time, `-j4` | 167 s | +| build tree | 125 MB (source 70 MB) | +| toolchain | 1.6 GB | + +`monerod-box` had **2 GB** when this was measured (it has since been raised to +6 GB, for monerod's own sake — see below). It was tried at 768 MiB and 1800 MiB, +at `-j1` and `-j2`, and every combination was OOM-killed — a single translation unit +exceeding 3 GB is not something lower parallelism can work around. Disk was +never the constraint; the often-quoted "~10 GB" for a monero build describes +upstream's full `make`, which also produces monerod, both wallets and the test +suite, none of which are linked here. + +So the binary is built elsewhere by **`scripts/build-xmrblocks.sh`**, which runs +the whole thing in a `debian:13` container. That matters: an artifact only one +machine can produce is an artifact nobody can audit. Any host with Docker and +~6 GB of RAM reproduces it, and the script verifies the monero source against +binaryFate's GPG signature exactly as `roles/monero` does for the daemon. + +The role refuses to ship anything it has not checked: `xmrblocks_sha256` is +asserted **on the control node, before the copy**, against the value the build +script prints. + +## Three upstream problems, and the fixes + +None of these are documented anywhere. All three were found by building. + +1. **`libasio-dev` is missing from upstream's dependency list.** The Dockerfile + is Ubuntu-based and installs `libboost-all-dev`; Crow wants standalone + `asio.hpp`, not `boost/asio.hpp`. On Debian 13 the build dies with + `asio.hpp: No such file or directory`. + +2. **The explorer does not compile against monero v0.18.5.1.** v0.18.5.0 changed + + ```cpp + crypto::hash get_pruned_transaction_hash(const transaction&, const crypto::hash&); + bool get_pruned_transaction_hash(const transaction&, const crypto::hash&, crypto::hash& res); + ``` + + and `src/page.h` still calls the old form. Upstream's Dockerfile pins + `MONERO_BRANCH=v0.18.4.0`, which is why nobody has hit it. The build script + applies a one-line patch, **anchored on the exact source line** so that if + upstream ever fixes it the build stops loudly instead of silently doing + something else. + + We patch rather than build against v0.18.4.0 deliberately: the current signed + `hashes.txt` only covers the current release, so using the older source would + mean giving up the provenance chain. The LMDB format is `VERSION 5` in both, + so either version reads the other's database safely. + +3. **`FindMonero.cmake` looks for miniupnpc inside the monero build tree** with + `NO_DEFAULT_PATH`, but monero stopped vendoring miniupnp as a submodule. Fixed + with a `-D Xmr_MINIUPNPC_LIBRARY=` cache override pointing at the system + library, rather than patching their cmake. + +`USE_DEVICE_TREZOR=OFF` is also passed: an explorer has no use for hardware +wallet support, and it drops the generated protobuf units, which are among the +heaviest to compile. `xmrblocks` was verified to link against the resulting +libraries. + +## Two things the unit gets right that look wrong + +**`WorkingDirectory` is load-bearing.** `src/page.h` hardcodes +`#define TMPL_DIR "./templates"` — the HTML is resolved relative to the process +working directory, at request time. Get it wrong and the service starts happily, +listens on 8081, and returns 500 for every page. That is also why the health +check fetches a real page and greps it rather than just probing the port. + +**`ReadWritePaths` must include the blockchain directory**, even though the +database is opened read-only. `MicroCore::init` sets `DBF_RDONLY`, and monero's +`db_lmdb.cpp` turns that into `mdb_flags = MDB_RDONLY` **without `MDB_NOLOCK`** — +so LMDB still registers this process in the reader table inside `lock.mdb`. With +`ProtectSystem=strict` and nothing writable, the open fails outright. The +intuitive "it only reads, grant it nothing" is wrong. `data.mdb` itself remains +read-only to the process, and writing to monerod's lock table is what any second +reader does. + +## Exposure + +Published by `caddy_site` on the edge host at `exmrplore.contrapeso.xyz`, with +TLS terminated there and the upstream reached over the tailnet via MagicDNS. + +The explorer listens on `0.0.0.0:8081`. Nothing on the LAN or the internet +reaches that directly: Tailscale's `ts-input` chain sits ahead of UFW, so only +tailnet peers can, and the Headscale ACL grants `tag:prd-vipy` exactly +`tag:monerod-box:8081`. A node with no ACL rule is *invisible* rather than +merely unreachable — it never appears in `tailscale status`, MagicDNS does not +resolve it, and the symptom is a Caddy 502 saying "no such host". + +**There is no authentication, by choice.** A block explorer serves public chain +data. But note what that includes: `--enable-pusher` is on (upstream's default), +so any visitor can submit a raw transaction and have *our* node relay it. That is +a deliberate decision, not an oversight — drop `xmrblocks_enable_pusher` to +`false` to close it. + +`--enable-json-api` and `--enable-autorefresh-option` are likewise upstream's +defaults. + +## Monitoring + +| Endpoint | Source | Answers | +|---|---|---| +| `services/monerod-box-local/xmrblocks` | `infra/401` via `monitored_services` | is the unit active | +| `probe/xmrblocks` | this role + `infra/403` | does it serve a real page | +| `dns/exmrplore.contrapeso.xyz`, `public/exmrplore` | `infra/402` | can the internet reach it | + +`public/exmrplore` asserts **200**, unlike the Monero RPC endpoint next door +which asserts 401 — this one genuinely has no auth in front of it. + +The timer carries no `Requires=xmrblocks.service`; see the comment in +`healthcheck.timer.j2` for why that would be backwards. + +## Backups: none, deliberately + +Everything here is derived or reproducible: the binary comes from +`scripts/build-xmrblocks.sh`, the templates ship with it, and the data it serves +is monerod's blockchain, which is itself excluded for the same reason. There is +no state on this service worth a backup job. Recorded as a decision so it does +not read as an oversight — the same treatment `phoenixd` and `monero` get. + +## Upgrading + +1. Edit the pins at the top of `scripts/build-xmrblocks.sh` (`EXPLORER_COMMIT`, + and `MONERO_VERSION` + `MONERO_SRC_SHA256` together). +2. Run it. It prints the new artifact sha256. +3. Put that in `xmrblocks_sha256` and `xmrblocks_explorer_commit` here. +4. Converge. The role asserts the checksum before copying anything. + +If the patch anchor no longer matches, the script stops — read the diff before +forcing it. + +## Runtime cost, and the RAM history + +On **2026-09-20 the VM was raised from 2 GB to 6 GB**, and that was not for the +explorer. monerod alone had outgrown 2 GB once the chain passed ~39%: it was +OOM-killed twice in one morning at 1.74 GB anon-rss, restarting every hour. With +6 GB the box sits at ~1.2 GB used of 5.9 GB with both services running +(monerod ~1.0 GB, xmrblocks ~96 MB). + +**The disk is the real performance limit, not memory.** `proxmox-tank-1` is a +spinning-disk mirror, and xmrblocks says so on startup: *"The blockchain is on a +rotating drive: this will be very slow, use an SSD if possible"*. Measured +consequences, both of which the role accounts for: + +- first start takes ~98 seconds to open the LMDB before it binds, so + `wait_for` allows 300s +- a COLD index page took **68 seconds**, while the two requests after it took + 0.87s and 0.012s — so the health check allows 90s and its unit 180s. A short + timeout there does not detect a slow explorer, it manufactures false DOWNs. + +Footprint note: xmrblocks mmaps the LMDB, so most of its apparent size is +reclaimable page cache rather than anonymous memory, and `--concurrency` is held +at 2 for the same reason. diff --git a/ansible/roles/xmrblocks/defaults/main.yml b/ansible/roles/xmrblocks/defaults/main.yml new file mode 100644 index 0000000..d90cab8 --- /dev/null +++ b/ansible/roles/xmrblocks/defaults/main.yml @@ -0,0 +1,75 @@ +# xmrblocks - the Onion Monero Blockchain Explorer. +# https://github.com/moneroexamples/onion-monero-blockchain-explorer +# +# This role INSTALLS a prebuilt binary; it does not compile one. xmrblocks links +# 21 static libraries out of a compiled monero source tree, and building that +# needs ~3.2 GB of RAM for a single compiler (~5.5 GB at -j4). monerod-box has +# 2 GB, so it cannot build this at any -j.

The authoritative record. | -| `monitors.json` | The same data, machine-readable, as returned by the API. | -| `deploy_uptime_kuma_playbook.yml` | How the server itself was deployed (Docker Compose on `monitoring`, behind Caddy). | -| `uptime_kuma_vars.yml` | Variables the deploy playbook needed — it is unreadable without these. | -| `setup_backup_uptime_kuma_to_lapy.yml` | How its data was backed up, and to where. Useful when disposing of the old volumes. | - -## Why the inventory was captured from the live server, not the repo - -The playbooks only ever created **17** monitors. The live instance had **75**. The -difference was created by hand in the UI and existed nowhere else — so a repo-derived -list would have silently lost two thirds of the picture. `MONITORS.md` is a snapshot of -the real thing, taken immediately before removal. - -Push tokens are deliberately excluded.

They are harmless but they are -still there, writing logs and failing quietly. - -Left behind, per host: - -- `/opt/disk-monitoring` + `disk-usage-monitor.{service,timer}` — on all 12 `managed` hosts -- `/opt/system-healthcheck` + `system-healthcheck.{service,timer}` — on all 12 `managed` hosts -- `/opt/nodito-monitoring` + `nodito-cpu-temp-monitor.{service,timer}` — `nodito` -- `/opt/zfs-monitoring` — `nodito` -- `/opt/ups-monitoring` — `nodito` -- `bitcoin-knots-healthcheck.{service,timer}` — `bitcoin` -- `datum-gateway-healthcheck.{service,timer}` — `bitcoin` -- `fulcrum-healthcheck.{service,timer}` — `electrum` -- `mempool-{backend,frontend,mariadb}-healthcheck.service` — `mempool` -- phoenixd and forgejo-runner healthcheck units — `edge`, `ci_runner` -

Nothing about that was a monitoring success: the checks were right, the cadence was wrong. monerod-box is a Monero node in the middle of a multi-week initial sync on a rotating disk. A 5-minute poll tells you nothing a daily one does not, and when something breaks it turns one fault into a message every five minutes until somebody silences the phone - which is the failure mode that makes people stop reading alerts entirely. So both Monero probes move to OnCalendar: monerod *-*-* 05:00:00 RandomizedDelaySec=900 xmrblocks *-*-* 05:30:00 RandomizedDelaySec=900 systemd units (infra/401 per-host timer) *-*-* 05:15:00 30 minutes apart on purpose: both read the same LMDB, and the explorer's check renders a full page out of it - a cold one measured 68 seconds. Running them together would have each paying the other's cache misses. OnCalendar rather than OnUnitActiveSec: an interval timer re-bases on every restart, so "daily" silently becomes "a day after whenever it last came up". ── The window and the cadence are ONE decision ───────────────────────────── The Gatus heartbeat moves with them, to 26h. Not 24h: the window must EXCEED the push interval, or a check reporting exactly on schedule races its own deadline and alerts on jitter alone. With a 900s randomized delay the true worst case is ~24h15m, so 26h leaves real headroom. The same logic drops the pulled public-site checks to a 24h interval - and their failure-threshold from 3 to 1 with it. Three failures at 5m is 15 minutes of tolerance; three at 24h would be THREE DAYS before anyone heard. A daily check has no room for a blip, so it alerts on the first. ── Scoping ──────────────────────────────────────────────────────────────── infra/401's timer is ONE PER HOST and iterates every unit in monitored_services, so slowing it slows all of them. That is safe here only because monerod-box runs nothing but Monero units; the knobs are therefore in its host_vars rather than the role, and both 401 and 403 now take a per-host (resp. per-probe) override with the old 11m as the default. Every other host is untouched. Host liveness and disk are deliberately NOT slowed. They answer "is the box alive", which is still wanted within minutes. The role-level OnCalendar defaults are prefixed (monero_healthcheck_on_calendar, xmrblocks_healthcheck_on_calendar) because the generic `healthcheck` role owns the unprefixed name, and an unprefixed default here would shadow it for any play that includes both.

Flip `enabled` back to true under the signal provider's default-alert to turn it on. Why one key reaches all ~90 endpoints: Gatus merges a provider's default-alert into each endpoint's alert for every field the endpoint left unset, and `enabled` is the only alert field no registration playbook sets. So this works without editing a single endpoint and without unregistering anything. The dashboard keeps checking and keeps showing red; it just stops sending. Deliberately NOT done by deleting the `signal:` provider block. That would strand ~90 endpoints referencing a provider that no longer exists, and throw away the number and the recipient list with it. The thing that made this necessary - a 5-minute poll turning one wedged service into 83 messages in six hours - is fixed properly in the preceding commit. This key is the blunt instrument that bought time to do that, and it should be turned back on once the cadence change has been observed for a few days. Known consequence while it is off: nothing pages. A six-day xmrblocks outage went unannounced precisely because of this.

A single Go binary with a SQLite database; the only external dependency is ffmpeg for transcoding. Plus beets, the CLI that fixes tags before Navidrome ever indexes them. ── Exposed without basic auth, on purpose ───────────────────────────────── Navidrome speaks two protocols on one port: its web UI, and the Subsonic API (/rest/*) that every mobile client actually uses. A Subsonic client authenticates with ?u=&t=md5(password+salt)&s= in the query string and has nowhere to carry a second credential, so Basic Auth in front of the site is invisible to most of them. The choice is a proxy credential or a working phone. Same call this estate already made for monerod's restricted RPC, for the same reason: proxied bare so Feather can reach it, with the service's own auth doing the authenticating. The cost is stated rather than glossed: the login page and the whole /rest/* surface are reachable by anyone who finds the hostname, and Navidrome has no rate limiting and no 2FA. A fail2ban jail on vipy reads a per-vhost Caddy access log and catches WEB UI brute force, where a bad login returns 401. It very likely does NOT catch Subsonic brute force, because that protocol answers a bad password with HTTP 200 and puts the failure in the body - which Caddy never sees. Nor can it be fixed on the music box: the request arrives from vipy over the tailnet, so the only address fail2ban could ban there is vipy's, which would take down every service behind the edge. Banning has to happen at the edge; the edge cannot see the failure. So /rest/* is protected by password strength alone, and the README carries a one-line curl to re-check that after every upgrade. ── Passwords are stored reversibly, and cannot not be ───────────────────── The Subsonic API requires the server to compute md5(password+salt) per request, so Navidrome cannot hash passwords one-way. It encrypts them at rest with PasswordEncryptionKey instead. Two real consequences, both in the README: root on that box means every Navidrome password in plaintext, so the password must be unique to this service; and changing the key invalidates every stored password, so it is set before the first account and left alone. ── beets is not a service, deliberately ─────────────────────────────────── `beet import` is interactive and it MOVES AND RENAMES FILES. A timer that reorganises a music library unattended is a way to lose one. Installed and configured, run by hand. /srv/music is counterweight:navidrome mode 2750 and the setgid bit is load-bearing: without it beets' files land in the curator's own group, Navidrome cannot read them, and the symptom is an EMPTY LIBRARY rather than a permission error. ReplayGain and lyrics are auto: no - on one core they turn a two-minute import into a twenty-minute one. ── Monitoring ───────────────────────────────────────────────────────────── Host liveness and disk (400), the systemd unit (401), a probe that fetches /app/ and greps it (403), and public reachability plus cert expiry (402). /app/ was chosen by testing all three candidates against 0.64.0: /ping returns a bare "." and proves only that something listens; /rest/ping.view identifies the server but logs two warnings per call, ~576 a day; /app/ returns Navidrome and logs nothing. 402 asserts 200 on /app/ and not on "/", because "/" answers 302 - checked live rather than assumed. ── Also ─────────────────────────────────────────────────────────────────── The headscale ACL grants tag:prd-vipy exactly tag:music-box:4533. Without a rule the node is invisible rather than unreachable, which surfaces as a Caddy 502 "no such host". inventory lan_ip was read off nodito's ARP table for the VM's own MAC, not guessed - and .149 had belonged to another machine, whose stale host key made SSH refuse the connection. That is the designed behaviour, not a fault. 50 GB is the LIBRARY ceiling, not just the OS: /srv/music is on the root disk, so roughly 300-450 albums in FLAC. 1 GB is fine for serving and tight for the initial scan, which is the memory peak. No backups, deliberately. The music files would swamp the age-encrypted nightly path, and navidrome.db is a rebuildable index. What is NOT rebuildable is playlists, play counts, ratings and accounts - there are none today, which is what makes the trade fair, and the README names this as the decision to revisit if that changes.

There is no `basic_auth` in +front of it, and that is a decision rather than an omission. + +The reason is the Subsonic API. A Subsonic client authenticates with +`?u=&t=&s=` in the query string and has nowhere +to put a second set of credentials. HTTP Basic Auth in front of the whole site +is invisible to most of them, so the choice is between a proxy credential and a +working phone. This estate has made the same call before, for the same reason: +`monerod`'s restricted RPC is proxied bare so Feather can reach it, and its own +Digest auth does the authenticating. + +The cost is stated plainly: Navidrome's login page and the whole `/rest/*` +surface are reachable by anyone who finds the hostname. Navidrome has **no rate +limiting and no 2FA**. The fail2ban jail below covers part of that gap. + +### The fail2ban jail on `vipy`, and what it does not cover + +Installed by the edge play in `services/navidrome/deploy_navidrome_playbook.yml`, +reading a per-vhost Caddy access log at `/var/log/caddy/music.log`. + +It catches **web UI brute force**: a bad login on `/auth/login` returns HTTP +401, which lands in the access log and trips the filter. + +It very likely does **not** catch Subsonic API brute force, because the +Subsonic protocol answers a bad password with **HTTP 200** and puts the failure +in the body (``). +Caddy never sees response bodies, so a status-code filter is blind to it. + +The obvious fix does not work either. Navidrome's own journal logs those +failures, but the request arrives from `vipy` over the tailnet, so the only +address fail2ban could ban on this box is `vipy`'s — which would take down every +service behind the edge. Banning has to happen at the edge; the edge cannot see +the failure. + +So: `/rest/*` is protected by password strength alone. That is the reason the +Navidrome password must be long, random, and used nowhere else. + +To re-check whether this is still true after a Navidrome upgrade: + +```bash +curl -s -o /dev/null -w '%{http_code}\n' \ + 'https://music.contrapeso.xyz/rest/ping.view?u=x&p=wrong&v=1.16.1&c=test' +``` + +`200` means the caveat holds. `401` means it no longer does — widen the jail +and delete this section. + +## Passwords are stored reversibly + +Navidrome **cannot** hash user passwords one-way. The Subsonic API requires the +server to compute `md5(password + salt)` on every request, so it must be able to +recover the plaintext. It encrypts passwords at rest with +`PasswordEncryptionKey` instead (`navidrome_password_encryption_key`, from +`group_vars/all/vault.yml`). + +Two consequences, both real: + +- Root on this box means every Navidrome password in plaintext. **Use a password + unique to this service.** +- **Changing the key invalidates every stored password.** Set it before the first + account exists and leave it alone. + +## Backups: none, deliberately + +Recorded as a decision so it does not read as an oversight — the same treatment +`phoenixd`, `monero` and `xmrblocks` get. + +The music files are large and would swamp the age-encrypted nightly path that +`backup_source` uses. `navidrome.db` is mostly a rebuildable index: delete it and +a rescan reconstructs the library. + +What is **not** rebuildable is the curation on top — playlists, play counts, +ratings, starred items, user accounts. Today there is none of it, which is why +this is a fair trade. **If that changes, this is the decision to revisit**, and +the fix is small: `navidrome.db` is a single SQLite file and would fit the +`backup_source` pattern in about fifteen lines. + +The beets database (`/var/lib/beets/library.db`) is in the same position — it +can be rebuilt from the tags beets itself wrote into the files. + +## beets + +Installed and configured by this role; **not** a service, and deliberately so. +`beet import` is interactive and it *moves and renames files*.

Organising by `$artist` instead scatters +every compilation and every "feat." track into a phantom artist, which is how a +library ends up unusable and Navidrome gets blamed for it. + +ReplayGain and lyrics are set `auto: no` — on one core they turn a two-minute +import into a twenty-minute one.

A docker:dind sidecar now runs on forgejo-runner-box, published on 127.0.0.1 only, and jobs build against that instead of the host daemon. Following Forgejo's own admin docs, which make the point that this is THREE settings and not one: forgejo-dind.service a privileged docker:dind on the host daemon container.docker_host tcp://127.0.0.1:2376 - where the runner CREATES job containers runner.envs.DOCKER_HOST + tcp://forgejo-dind.docker.internal:2375 - container.options how a job, from INSIDE dind, reaches it The third is the one that is easy to miss and fails identically to having done nothing: for a tcp:// docker_host the runner mounts nothing into the job container, so the job still finds no daemon. The two addresses differ because they are used from different places - the runner is a process on the host; a job container is inside dind, where 127.0.0.1 is itself. `host-gateway` is expanded by the daemon creating the container, which is dind, so it lands on dind's own bridge gateway. Verified on the box, along the exact path a job takes - a container on a user-defined network, with the same --add-host and DOCKER_HOST the runner will set: the name resolves to 172.20.0.1, `docker version` returns the dind server, and `docker build` succeeds. The host daemon runs forgejo-dind and nothing else. config.yml had to become a template to do any of this. It was previously `generate-config` run once on first deploy and never touched again, so the repo had no say in its contents. Every value was transcribed from the live file and diffed against it key by key: with dind disabled, 30 of 30 identical. Two deliberate differences - runner.envs drops A_TEST_ENV_NAME_1/2, upstream's placeholders, which were being injected into every job here; and the upstream comment blob is gone. Because the file is managed now it also gets a restart handler, the absence of which has bitten this repo before. Things deliberately chosen rather than defaulted into: - the flag lives in the playbook, not the role defaults, so the role's default stays the configuration this host has always run and turning it off is one line. Disabling it also tears the units down rather than just skipping them. - dind is a hard Requires= of forgejo-runner, and its unit stays in "activating" until the daemon answers. A dead dind is then one red unit instead of a green runner failing every job it claims. - the healthcheck and monitored_services learned about dind for the same reason: runner up + dind down is the interesting failure and it was previously invisible. - /var/lib/docker is a named volume, or every image is re-pulled on each container recreation; a weekly prune keeps that from growing forever. - dind's network pool is pinned to 172.20.0.0/14. Docker's stock pool reaches into 192.168.x, and act_runner creates a network per job, so a job could eventually allocate this LAN's subnet and lose the route to every box on it. Note this runner is SHARED - arbret, arbret-biz, arbretdos and arbret-ops build here too, far more often, and docker_host is per-runner not per-repo. Their workflows are unchanged but their next run pulls images into a cold cache. Job images still need a docker client of their own: node:{20,22}-bookworm ship none.

The two +addresses differ because they are used from different places — the runner is a +process on the host and reaches dind on loopback; a job container is *inside* +dind, where `127.0.0.1` is itself. `host-gateway` is expanded by the daemon +that creates the container, which is dind, so it lands on dind's own bridge +gateway where its `dockerd` is listening. + +### What changes for jobs + +- Job containers, service containers and anything a job starts all live on the + dind daemon. A `postgres` service and a `docker compose` stack are siblings + there, so they reach each other by name — which is what makes end-to-end + tests work. +- **Nothing a workflow does can touch this host's Docker daemon any more.** + That is the point of dind over `automount`. +- dind has its own image store. Every image is pulled again the first time it + is needed. It is a named volume (`forgejo-dind-lib`), so it survives the + container being recreated, and `forgejo-dind-prune.timer` drops weekly what + has gone a week unused. +- Bind mounts inside a job's own `docker compose` resolve on the **dind** + filesystem, not the job container's. A compose file that bind-mounts the + checked-out repo will not see it. Named volumes and `build:` contexts are + fine. This is inherent to dind, not to this role. + +### Things to know before enabling + +- **This runner is shared.** `arbret`, `arbret-biz`, `arbretdos` and + `arbret-ops` build here too, and `container.docker_host` is per *runner*, not + per repo — every one of them moves onto dind. Their workflows do not change; + their next run pulls images into a cold cache. +- **`capacity` is 4 and dind is one daemon.** Concurrent jobs can see and touch + each other's containers and images through the Docker CLI. Forgejo's docs + call this out. Fine for a single-tenant runner; set `capacity: 1` if + untrusted code ever runs here. +- **The dind container is `--privileged`**, which is why this belongs on a + dedicated CI VM and not beside anything that matters. `forgejo-runner-box` + runs the runner and nothing else. +- **The daemon has no TLS and no authentication.** It is published on + `127.0.0.1` only, so reaching it means already having a shell on this box — + but it does mean any local user is root in a privileged container. Do not + move `forgejo_runner_dind_bind_address` off loopback. +- **The `runner` user is still in the host `docker` group**, left over from + when the runner used the host daemon. With dind it no longer needs it. Worth + removing, deliberately, as its own change. +- **`cache.host` is autodetected**, and job containers now reach the runner's + cache server across dind's NAT. Autodetect returns this box's LAN address, + which is routable from in there. If `actions/cache` starts silently missing, + pin `forgejo_runner_cache_host` — that is the first place to look. +- **Deploy when the runner is idle.** `shutdown_timeout` is 3h, so restarting + it mid-job waits for the job. + +### Turning it off + +Set `forgejo_runner_dind_enabled: false` and re-run. The role stops and +disables the units, removes them, and puts `container.docker_host` back to +`"-"` — the exact configuration this host ran before. The image and the +`forgejo-dind-lib` volume are left alone: they are a cache, they hold no +secrets, and deleting them on a toggle is not the role's call. + +## `config.yml` is templated now + +It used to be `forgejo-runner generate-config`, run once on first deploy and +never touched again — so the repo had no say in anything inside it, including +the setting this feature needs. It is now `templates/config.yml.j2`. + +Every value in it was transcribed from the file live on `forgejo-runner-box` +and diffed key-by-key against it: with dind disabled, 30 of 30 keys are +identical. Two deliberate differences: + +- `runner.envs` no longer carries `A_TEST_ENV_NAME_1` / `A_TEST_ENV_NAME_2`, + upstream's example placeholders, which were being injected into every job. +- the upstream comment blob is gone; the values are not. + +Because the file is managed, a change to it now restarts the runner +(`handlers/main.yml`).

New role roles/jar_lid_archive; per-host values in host_vars, so a production host is a new [jar_lid_archive] entry, not a new playbook. ── Containers, following :master ────────────────────────────────────────── The same three services as the app repo's compose.yaml, so staging rehearses what dev and CI run. Every playbook run pulls :master and `up -d --wait`s; compose recreates web only when the digest moved. --wait gates on web's /health/, which checks the database and the bucket, so a green run means the app serves. Upgrading is re-running the playbook. ── web is on the host network ───────────────────────────────────────────── Docker's published ports are DNATed before UFW sees them, so `8000:8000` would answer on the LAN whatever UFW says, and binding to the tailnet IP races tailscaled at boot. On the host network gunicorn's port is an ordinary one: UFW default-deny covers the LAN, tailscaled's ts-input accepts tailscale0 ahead of UFW (checked on mempool-box), and the headscale ACL grants tag:prd-vipy exactly :8000. db and storage publish on 127.0.0.1 only. Verified: LAN times out, vipy gets 200. That matters for HTTPS: the app trusts X-Forwarded-Proto (DJANGO_BEHIND_TLS_PROXY=1), which is only safe while Caddy is the sole client. Login POST through the public URL passes CSRF; cookies are Secure. ── Secrets ──────────────────────────────────────────────────────────────── Generated straight into host_vars/jar_lid_staging_local/vault.yml, never printed: Django key, Postgres and S3 secrets, and seed passwords for the fixture's alice/bob/admin usernames - never the fixture's published passwords, since the site is public. The group vault gains one line, this host's Gatus push token; decrypted, it differs from before by exactly that line. ── Backups, and the outage the first one caused ─────────────────────────── One uncompressed tar (pg_dump -Fc + the SeaweedFS data dir), age-encrypted on the box at 02:20, pulled by small-backups-box; 3 days at both ends. Verified end to end, including decrypting a pulled artefact on lapy. The first test run stopped web AND storage and left the app down 26 minutes: SeaweedFS outlasted its 150s healthcheck budget on this disk, compose marked it unhealthy, and web's depends_on never started it. Now only web is stopped - it is the only writer to both stores, so they are still captured at one instant - and the healthchecks have start_periods sized for the disk. Also inherited from the app's compose.yaml: storage writes /tmp/s3.json and chowns it to seaweed, so on a RESTART of the same container root cannot re-create it (sticky /tmp + protected_regular): "Permission denied". Fixed here with rm -f first; the app repo needs the same line. ── The disk is the problem ──────────────────────────────────────────────── The VM disk is on proxmox-tank-1, the HDD mirror, which knots-box's random reads (~6 MB/s) keep near saturation. Inside this VM: ~96% "full" I/O pressure while idle, ~5 min to start web, sudo occasionally over 12s. Moving it to local-zfs (NVMe) is the fix; noted in the README, not done. ── Also ─────────────────────────────────────────────────────────────────── - lan_ip read from the Proxmox guest agent; host key checked against the one the agent reads off the disk before it went into known_hosts. - Monitoring: liveness + disk (400), probe_jar-lid-archive-staging (403), public /health/ + DNS (402), backup-dump/backup-store. - tofu: the VM definition. - Deployed v2026.10.03.1.

The app is told to trust `X-Forwarded-Proto` +(`DJANGO_BEHIND_TLS_PROXY=1`), which is only safe while Caddy is the only +thing that can reach gunicorn. Caddy overwrites whatever value the client sent. + +## Secrets and seed users + +The Django secret key, the Postgres password, the S3 secret and the three seed +passwords were generated into `host_vars/jar_lid_staging_local/vault.yml`. They +reach the box as `/opt/jar-lid-archive/.env` (0600, root), which compose +interpolates. `docker-compose.yml` itself has no secrets. + +The seed users are alice, bob and admin (superuser), with the fixture's usernames +and **vault** passwords. The fixture's `*-test-pass` passwords are published in +the app repo and this site is public. `seed_users` runs on every deploy and +resets each listed user's password, so rotating one means editing the vault and +re-running the playbook. + +```sh +ansible-vault view host_vars/jar_lid_staging_local/vault.yml # from ansible/ +``` + +## Backups + +`services/jar-lid-archive/setup_backup_jar_lid_archive.yml` uses +`backup_source`. At 02:20 it stops `web` only, and +`/usr/local/bin/jar-lid-archive-dump.sh` writes one tar with: + +- `db.dump`: `pg_dump -Fc` +- `seaweedfs/`: the photo store's data directory, as files + +`web` is the only writer to the database and the photo store. With it stopped, +both are quiet and are captured at the same instant. `storage` is deliberately +left running: on this disk it can take minutes to restart, and the first test run +that stopped it left the app down for 26 minutes. Uploads fail while `web` is +down. + +The tar is not gzipped, because the bulk is JPEGs. Three days are kept locally, +and small-backups-box keeps three as well.

The root-disk guard caught it, but a routine run should never have been reading a device name at all. Every run now looks for the filesystem labelled monero-data first. If it is there, monero_data_device is never consulted and the mount goes by that filesystem's UUID. Only a blank disk is found by name, and the name is now /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi1: Proxmox passes the slot in as the serial, so it is fixed before boot and survives `qm disk move`. The by-id path is resolved with readlink before the root-disk guard compares it, since a symlink path is never a prefix of /dev/sdb1 and the guard would otherwise always pass. The UUID assert now also fails on two disks carrying the same label.

That stopped being true: the node is synced, and a cold explorer page now renders in 29s and a warm one in 0.2s - polling every 5 minutes is what keeps it warm. A dead monerod could go unnoticed for a day. Back to the standard 5m cadence and 11m heartbeat; the per-host service_health override on monerod-box is gone.

Steady-state reads did drop (to ~0.4 MB/s) and RPC rejections went to zero. But block validation got SLOWER over the next 14 blocks: median 60s against 11s before. bitcoind's bench log puts all of it in input lookups at ~5 ms each. The likely cause is that the extra GB came out of the guest's page cache, which holds compressed chainstate files far more densely than bitcoind's cache holds decoded coins. Committed because it is what is running; probably to be reverted.

A pulled check on the account API alerts when billing.secondsdue - the provider's own runway at current spend - drops under 14 days: checked every 6h, reminding every 24h. gatus_endpoint gains a `headers` field for APIs behind a credential. The vault gains ninetyninestack_api_token (account-wide; 99stack has no read-only scope) and gatus_push_tokens.arbret, used by the next commit.

There are two kinds of check: + +- **Pulled.** Gatus makes the request itself (HTTP, TCP, DNS) every N seconds and + evaluates conditions. Nothing is installed on your side. This is the right kind for + anything with a reachable URL. +- **Pushed ("external endpoints").** Something on the host `POST`s a result to Gatus, + and Gatus alarms if a result is `false` **or if nothing arrives within the heartbeat + window**. This is the right kind for things with no URL: timers, jobs, internal state. + The heartbeat is what makes a dead timer visible: silence is a failure. + +Everything about an endpoint (name, group, token, heartbeat, alert rules) is defined in +**our** repo, because Gatus's config files live on prd-spacey. Your side of a push check +is just an HTTP call. + +### 2.2 The push API + +``` +POST https://status.contrapeso.xyz/api/v1/endpoints/{KEY}/external?success={true|false}&error={message} +Authorization: Bearer {TOKEN} +``` + +- **`KEY`** is `sanitize(group) + "_" + sanitize(name)`, where sanitize lowercases and + turns any of `/ _ . , space # + &` into `-`. Use the exact keys in the table below. +- **`success`**: `true` or `false`. +- **`error`**: free text, URL-encoded. It's shown on the dashboard and in the Signal + alert, so on success it's fine to send something useful like `ok 31M`. +- **`TOKEN`**: a bearer token we give you (§4). It's dedicated to arbret: it can only + write arbret's endpoints, and nobody else's token can write yours. + +Responses: + +| HTTP | Meaning | +|---|---| +| `200` | recorded | +| `401` | wrong token for that key | +| `404` | key not registered (yet).

So no wrapper script is needed, and the run itself stays untouched. + +`/etc/arbret/gatus.env` (`root:root 0600`): + +``` +GATUS_PUSH_BASE=https://status.contrapeso.xyz/api/v1/endpoints +GATUS_PUSH_TOKEN= +``` + +`/usr/local/bin/arbret-gatus-push` (`root:root 0755`): + +```bash +#!/usr/bin/env bash +# Usage: arbret-gatus-push +# Meant for ExecStopPost=, where systemd provides SERVICE_RESULT / EXIT_STATUS. +# Can also be called by hand: SERVICE_RESULT=success arbret-gatus-push +set -uo pipefail +KEY="$1" +: "${GATUS_PUSH_BASE:?}" "${GATUS_PUSH_TOKEN:?}" + +if [ "${SERVICE_RESULT:-}" = "success" ]; then + success=true; msg="ok" +else + success=false; msg="${SERVICE_RESULT:-unknown} exit=${EXIT_STATUS:-?}" +fi +enc=$(printf '%s' "$msg" | sed 's/%/%25/g; s/ /%20/g; s/&/%26/g; s/+/%2B/g; s/#/%23/g; s/=/%3D/g') + +# Never let a monitoring hiccup fail the job itself. +curl -s -o /dev/null --max-time 15 --retry 2 --retry-delay 3 -X POST \ + -H "Authorization: Bearer ${GATUS_PUSH_TOKEN}" \ + "${GATUS_PUSH_BASE}/${KEY}/external?success=${success}&error=${enc}" || true +exit 0 +``` + +In the analytics service unit: + +```ini +[Service] +Type=oneshot +EnvironmentFile=/etc/arbret/gatus.env +ExecStart=...your existing command... +ExecStopPost=/usr/local/bin/arbret-gatus-push probe_arbret-analytics +``` + +Two things to get right: + +- `EnvironmentFile=` puts the token in the unit's environment, **not** in the unit file, + so the unit file can stay world-readable while the env file is `0600`. +- **Tell us the timer's schedule.** We set the heartbeat to the interval plus slack: a + 5-minute job gets an 11-minute window, a daily job gets 26 hours. If the schedule + changes later, tell us, or Gatus will either alarm on a healthy job or sleep through a + dead one. + +As Ansible, this is two templated files, an `EnvironmentFile=` line and an +`ExecStopPost=` line. It's small enough to live in the role that deploys the analytics +timer, rather than becoming a role of its own. + +### 2.5 Staging (arbret-staging-box) + +arbret-staging-box is a VM in our inventory, so its liveness and disk checks already +exist. The same mapping applies with these keys: + +| Check | Key | Who | +|---|---|---| +| front door / health | `public_arbret-staging`, `public_arbret-staging-health` | us | +| units | `services_arbret-staging-local-arbret-server` (and `-worker`, `-postgresql`) | us | +| analytics | `probe_arbret-staging-analytics` | you, with the **staging** token | +| backup dump | `backup-dump_arbret-staging` | you, with the staging token. Only if staging should be backed up; tell us. | + +The staging vhost (`arbretstaging.contrapeso.xyz`) lived on the old prd-vipy and was not +in either repo. We're recreating it on our side. + +--- + +## 3. Backups + +### 3.1 The pipeline + +``` + 02:00 UTC prd-vipy your timer: pg_dump | age -r -> /opt/backups/arbret/arbret_.dump.age + your script: POST backup-dump_arbret (success/failure) + 04:00 UTC small-backups-box rsync backup-pull@prd-vipy:/opt/backups/arbret/ -> ~/backups/arbret/ (keeps 90 days) + 05:30 UTC small-backups-box check-backups.sh -> POST backup-store_arbret (then every 6 h) +``` + +- **The box only pulls.** Nothing on prd-vipy can reach into the backup box. The pull + logs in as `backup-pull`, an unprivileged account with a `restrict`ed key that can + read the backup directories and nothing else. +- **The source encrypts.** Only the age **public** key is on prd-vipy, so the host can't + decrypt its own backups. The private key lives offline with the infra owner. Plaintext + never touches disk or the network. +- **Retention is two-tier.** Keep about 7 days locally (the disk is shared). The box + keeps 90. + +Your existing dump role already produces the right **artefact**: a Postgres custom-format +dump, age-encrypted, named `arbret_YYYYmmdd_HHMMSS.dump.age`. The last pre-incident one +is `arbret_20261016_020001.dump.age`. Only its **location, ownership and reporting** +change. + +### 3.2 What changes from prd-arbret + +| | prd-arbret | prd-vipy | +|---|---|---| +| Directory | `/opt/arbret/backups/` | **`/opt/backups/arbret/`** | +| Account the box pulls as | `arbret` (your user, with our key authorised) | **`backup-pull`** (ours, already exists) | +| SSH key for the pull | you authorised it | **nothing to do.** Remove that task, and don't authorise anything for `arbret` or `backup-pull`. | +| Result reporting | Uptime Kuma push | Gatus push to `backup-dump_arbret` | + +### 3.3 The contract + +The checks on the box enforce these, and some failures are silent, so read every line. + +1. **Directory:** `/opt/backups/arbret/`, owner `root`, group `backup-pull`, mode `0750`. + Don't change `/opt/backups/` itself (`root:root 0755`, ours). The `backup-pull` group + exists before your playbook runs; if it doesn't, fail loudly rather than creating it. +2. **Filename:** `arbret_YYYYmmdd_HHMMSS.dump.age`, timestamp in the host's local time + (UTC). The prefix must be exactly `arbret_`, because the box's prune and freshness + checks glob on `arbret_*`, and it reads the **dump time from the filename**. +3. **Encryption:** `age -r ` in the pipe (§4). Nothing unencrypted is ever + written to disk. +4. **Atomicity:** write `.partial`, set ownership and mode, then `mv` it to the + final name. The pull skips `*.partial`. A half-written file under the final name + would be pulled and kept for 90 days as if it were a backup. +5. **File ownership:** `root:backup-pull`, mode `0640`, on both the `.partial` and the + final file. If the pull account can't read a file, **rsync fails for the whole + directory**, so one bad file blocks every later night. +6. **`set -euo pipefail`.** Without `pipefail`, a failing `pg_dump` piped into a + succeeding `age` exits 0 and produces a tiny, valid-looking, useless artefact. +7. **Timing:** finished before 04:00 UTC. 02:00 is good. +8. **Local prune:** delete `arbret_*.dump.age` older than ~7 days, plus stale + `arbret_*.partial` files at the start of each run. Put nothing else in the directory: + no subdirectories, logs or checksums. +9. **Report** the outcome to Gatus on every exit path (§3.5). +10. **No service stop is needed.** `pg_dump` takes a consistent snapshot online. Don't + stop `arbret-server` for it. + +### 3.4 Reference script + +This is the same shape as the script every other service on the host uses (our +`backup_source` role), adapted to `pg_dump`.

Whether port 4117 over the tailnet is still needed. +5. The final unit names, if not `arbret-server`, `arbret-worker`, `postgresql`. +6. Whether staging should be backed up, and whether staging pushes are in scope. +7. Who besides the infra owner should get Signal alerts for arbret. + +Once we have 1 to 3, we register the endpoints, the vhost and the pull source. Then you +can deploy and see green on the first run.
