# 01. Infra Setup

This describes how to prepare each machine before deploying services on them.

## 01.01 First steps

* Create an ssh key or pick an existing one. We'll refer to it as the `personal_ssh_key`.
* The guide assumes the laptop (Lapy) has `ansible` installed. If not, do `sudo apt install -y ansible` and `ansible --version` to check.

## 01.02 Prepare the VPS (Vipy)

### 01.02.01 Source the VPS

* The guide is agnostic to which provider you pick, but has been tested with VMs from https://lnvps.net.
* The expectations are that the VPS ticks the following boxes:
  + Runs Debian 12 bookworm.
  + Has a public IP4 and starts out with SSH listening on port 22.
  + Boots with one of your SSH keys already authorized.
* Move on once your VPS is running.

### 01.02.02 Prepare Ansible vars

* You have an example `infra/example.inventory.ini`. Copy it with `cp example.inventory.ini inventory.ini` and fill in with the vars for your VPS.

### 01.02.03 First steps with Ansible

* cd into `infra`
* Run `ansible-playbook playbook.yml`
