deploy.yaml / ansible: remove the retired Minecraft Fossils role (push) Failing after 0s
The server is stopped and its data deleted (archived to object storage as minecraft-fossils-final-20261112.tar.zst), so the role that kept it stopped has nothing left to do. Assisted-by: Claude:opus-5-5

# Ansible
|
|
|
|
`site.yaml` is the desired state of both servers and is applied by the
|
|
deploy pipeline on every push to `main`. The playbooks under
|
|
`playbooks/` are host bootstrap and are run by hand.
|
|
|
|
## Running
|
|
|
|
```sh
|
|
echo '<vault password>' > .vault_pass && chmod 600 .vault_pass
|
|
|
|
ansible-playbook site.yaml --check --diff # dry run, over WireGuard
|
|
ansible-playbook site.yaml # apply
|
|
ansible-playbook site.yaml --tags forgejo # one role
|
|
```
|
|
|
|
On NixOS: `nix shell nixpkgs#ansible -c ansible-playbook …`.
|
|
|
|
Templates that carry secrets are never shown in `--diff` output.
|
|
|
|
## Inventories
|
|
|
|
- `inventory/hosts.yaml`: default. Connects as root to the WireGuard
|
|
addresses.
|
|
- `inventory/ci.yaml`: used by the pipeline. Connects as `deploy` over
|
|
the private network, reaching asxpio-services through asxpio-ops.
|
|
|
|
`known_hosts` pins both servers' SSH host keys for the pipeline.
|
|
|
|
## Variables
|
|
|
|
```
|
|
inventory/
|
|
├── group_vars/all/
|
|
│ ├── network.yaml # VPC and WireGuard addresses
|
|
│ ├── paths.yaml # /opt
|
|
│ ├── s3.yaml # object storage buckets and s3fs mounts
|
|
│ ├── wireguard.yaml # WireGuard peers
|
|
│ └── vault.yaml # encrypted secrets
|
|
├── group_vars/ops_servers/
|

|
│ └── minecraft.yaml

└── host_vars/ # per-host addresses, SSH and s3fs settings
|
|
```
|
|
|
|
Compose files without variables are plain files under
|
|
`roles/<role>/files/`; edit the image tag there.
|
|
|
|
## Roles in site.yaml
|
|
|
|
`base`, `traefik`, `crawler_alert`, `forgejo`, `forgejo_runner`,
|
|
`sillytavern`, `minecraft`, `xmpp`, `xray`, `restic_backup`. Service roles go
|
|
through `docker_service`, which writes the files, runs
|
|
`docker compose up -d`, restarts on a config change and waits for the
|
|
service to answer.
|
|
|
|
`crawler_alert` installs a copy of
|
|
[traefik-crawlers-statistics](https://git.asxp.io/asxpi/traefik-crawlers-statistics);
|
|
update `roles/crawler_alert/files/` from there.
|
|
|
|
## Bootstrap playbooks
|
|
|
|
| Playbook | Purpose |
|
|
|----------|---------|
|
|
| `01-wireguard-setup.yaml` | WireGuard hub on asxpio-ops, peer on asxpio-services, client configs |
|
|
| `02-ssh-hardening.yaml` | restrict SSH to WireGuard and the private network |
|
|
| `03-setup-s3fs.yaml` | s3fs mounts on asxpio-services (off on asxpio-ops) |
|
|
| `04-add-user-zerrtika.yaml` | add a user to running servers |
|
|
| `05-swap.yaml` | 2 GB swapfile on asxpio-ops |
|
|
|
|
Always dry-run these first with `--check --diff`.
|
|
|
|
- `03-setup-s3fs.yaml` rewrites `/etc/s3fs/.passwd-s3fs`, which the
|
|
backup script on asxpio-ops also reads.
|
|
- On asxpio-services the WireGuard interface is named
|
|
`asxpio-services`, not `wg0`. Check `01-wireguard-setup.yaml` against
|
|
the host before re-running it there.
|
|
|
|
## Runner notes
|
|
|
|
The `nix-latest` label runs `nixos/nix:<forgejo_runner_nix_version>`
|
|
with a `nix-store-<version>` volume over `/nix`. To bump it: change the
|
|
variable, let the pipeline apply it, then remove the old volume.
