subdomains:
gatus: deploy on prd-monitoring, behind Caddy basic auth First step of replacing Uptime Kuma and ntfy. 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 ("<group>_<name>"). 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 <token>`, 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.

monero: a full node on its own box, reachable from Feather over the WAN monerod v0.18.5.1 on monerod-box (VMID 2400), Debian 13, systemd, no Docker. 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 <fpr>` 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.

watchtower: remove from the estate, and with it ntfy watchtower is being destroyed. 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
