# ANOUMA — Deployment

Production deployment is fully CI/CD-driven via Gitea or GitHub Actions. There is no `update.sh` and the production server never builds anything — it only ever pulls a tested image from the registry.

```text
Developer → git push main → Gitea Actions (CI)
  → Tests → Docker Build → Registry Push (tagged by commit SHA)
  → Release (git tag vX.Y.Z) → promote that exact image to vX.Y.Z + latest
  → SSH → deploy.sh → docker compose pull → migrate → up -d → Healthcheck → LIVE
```

Building and testing happen exactly once, on `main` — tagging a release never
rebuilds or re-tests, it only promotes the already-verified image for that
commit. Tagging a commit that hasn't been pushed to `main` (or whose CI run
hasn't finished yet) fails the release with a clear error instead of quietly
building from source and skipping the checks.

## One-time server setup

```bash
git clone https://git.maro.run/maro/anouma.git
cd anouma
chmod +x setup.sh
./setup.sh
```

`setup.sh` needs root (directly or via `sudo`) because it creates a system user and writes to `/opt`. It:

1. Checks/installs Docker, Docker Compose, git, openssl, curl, ssh.
2. Creates `/opt/anouma` (refuses to touch it if an installation already exists there — you choose "use existing" or abort; nothing is ever deleted).
3. Detects an existing Nginx Proxy Manager network and optionally joins it.
4. Writes `/opt/anouma/.env` with every secret the app needs, freshly generated (`openssl rand -hex 32`) and **never regenerated** on a later run.
5. Asks the few things that can't be generated (domain, optionally SMTP, optionally the registry credentials) — skipped automatically if already answered before.
6. Creates a restricted `anouma-deploy` system user, generates a dedicated SSH keypair for it, and installs the public key with a **forced command** so that key can only ever run `deploy.sh` — never an interactive shell.
7. Copies `docker-compose.yml` and `deploy.sh` into `/opt/anouma`.
8. Starts Postgres (so it's ready for the first deploy).
9. Prints the exact values to paste into **Gitea → maro/anouma → Settings → Secrets → Actions**, including the deploy private key — shown only once, the first time the key is generated.

Run `./setup.sh --non-interactive` for a scripted install; any value that has no safe default and wasn't exported as an environment variable beforehand aborts with a clear message naming the missing variable, instead of silently guessing.

Re-running `./setup.sh` later (e.g. after pulling script updates) is always safe: existing secrets, the SSH key, the database and all volumes are left exactly as they are — only `docker-compose.yml` and `deploy.sh` themselves get refreshed, since those are generated artifacts, not data.

### After setup: add the Gitea secrets

Copy the block `setup.sh` printed into **Gitea → maro/anouma → Settings → Secrets → Actions**:

| Secret | Value |
| --- | --- |
| `DEPLOY_HOST` | the server's IP/hostname |
| `DEPLOY_PORT` | `22` (or your SSH port) |
| `DEPLOY_USER` | `anouma-deploy` |
| `DEPLOY_SSH_KEY` | the private key setup.sh printed |
| `DEPLOY_HOST_KEY` | optional — pin the server's SSH host public key instead of trusting it on first connect (`ssh-keyscan -p <port> <host>` on a machine you already trust) |
| `REGISTRY_USERNAME` / `REGISTRY_PASSWORD` | registry push credentials (a Gitea access token as the password, not your account password) |

### First deploy

Nothing runs on the server yet at this point — no release has been built. Push the first tag:

```bash
git tag v1.0.0
git push github v1.0.0   # GitHub Actions
# alternativ: git push origin v1.0.0   # Gitea Actions
```

The selected CI provider takes it from there (see below). Once it's live, seed the original content once: `ssh anouma-deploy@<host>` won't work (the key is restricted — see Security), so run it directly on the server instead: `cd /opt/anouma && docker compose run --rm app npm run seed`.

## Gitea Actions

### CI (`.gitea/workflows/ci.yml`)

Runs on every push and PR: `npm ci` → lint → typecheck → test → build, on the `ubuntu-latest`-labelled runner. No database is required — every Payload-backed route in this app is `force-dynamic`, so a production build never touches Postgres. (There's no automated test suite yet — `npm test` is an honest placeholder; add a real one, e.g. vitest, whenever the project needs it, and it'll run here automatically.)

On top of that, every push to `main` that passes the checks above also builds the Docker image and pushes it to the registry tagged by commit SHA (`git.maro.run/maro/anouma:<sha>`) — this is the one and only build of that commit; nothing later rebuilds it.

### Release (`.gitea/workflows/release.yml`)

Triggered by pushing a tag matching `v*` (e.g. `v1.2.0`):

1. Pulls the image CI already built and pushed for that commit's SHA — fails immediately with a clear error if it isn't there (the tagged commit was never on `main`, or CI for it hasn't finished yet).
2. Retags that same image as `git.maro.run/maro/anouma:vX.Y.Z` **and** `:latest`, and pushes both.
3. SSHes into the production server as `anouma-deploy` and runs `deploy.sh deploy vX.Y.Z`.

Production always runs a specific version tag — `latest` is pushed for convenience/reference only (and always points at the most recently *released* build, not just the newest commit on `main`), `deploy.sh` never uses it.

## GitHub Actions

The GitHub repository is `whitehai11/anouma`; the workflows live in
`.github/workflows/ci.yml` and `.github/workflows/release.yml`. In GitHub go to
**Settings → Secrets and variables → Actions → Repository secrets** and create:

| Secret | Required | Value |
| --- | --- | --- |
| `REGISTRY_USERNAME` | yes | Gitea Container-Registry username, normally `maro` |
| `REGISTRY_PASSWORD` | yes | Gitea access token/password with permission to push/pull `git.maro.run/maro/anouma` |
| `DEPLOY_HOST` | yes | Public IP or hostname of the production server |
| `DEPLOY_PORT` | yes | SSH port, normally `22` |
| `DEPLOY_USER` | yes | `anouma-deploy` |
| `DEPLOY_SSH_KEY` | yes | Private key generated by `setup.sh` for the restricted deploy user |
| `DEPLOY_HOST_KEY` | no | Complete SSH host-key line from a trusted `ssh-keyscan`; safer than first-connect trust |

Es werden keine zusätzlichen GitHub-Variables benötigt; Registry und Image
sind im Workflow fest auf `git.maro.run/maro/anouma` gesetzt. Runtime-Secrets
wie `PAYLOAD_SECRET`, `MEETING_SESSION_SECRET`, `LIVEKIT_API_SECRET` und
`DATABASE_URI` gehören ausschließlich in `/opt/anouma/.env` auf dem Server und
nicht in GitHub Actions.

Wichtig: Für Releases nur einen CI-Anbieter verwenden, damit nicht beide
Systeme dasselbe Image parallel bauen oder deployen. Für dieses GitHub-Setup
ist GitHub Actions die empfohlene Quelle; Gitea kann als Spiegel bestehen
bleiben.

## `deploy.sh` (server-side, `/opt/anouma/deploy.sh`)

Not a manual tool — it's invoked exclusively by Gitea Actions over SSH. What it does for `deploy.sh deploy vX.Y.Z`:

```text
Lock (refuse a second concurrent deploy)
  → Backup the database
  → Set ANOUMA_IMAGE in .env to the new tag
  → Registry login (if credentials are configured)
  → docker compose pull
  → docker compose run --rm app npm run migrate
  → docker compose up -d
  → Healthcheck
  → success, or: automatic rollback to the previous version
```

If the post-deploy healthcheck fails, `deploy.sh` automatically redeploys the **previous** version (recorded from `ANOUMA_IMAGE` before the attempt) and reports the failed deploy as exit code 1 — Gitea Actions shows the release as failed even though production recovered. Database migrations from the failed release are **not** reverted (write migrations to be forward-compatible); restore the pre-deploy backup manually if a migration truly needs undoing.

A lock file (`/opt/anouma/.deploy.lock`) prevents two deploys from running at once; a stale lock from a killed process is detected and ignored automatically.

## Backups

Every deploy backs up the database first, to `/opt/anouma/backups/database-YYYY-MM-DD-HHMM.sql.gz`, before anything else changes. Backups older than `BACKUP_RETENTION_DAYS` (default 14) are cleaned up automatically — the backup just created is never deleted, even if retention is set very low.

Restore manually if needed:

```bash
cd /opt/anouma
gunzip -c backups/database-2026-08-25-1430.sql.gz | docker compose exec -T postgres psql -U postgres anouma
```

## Nginx Proxy Manager (or any reverse proxy)

`setup.sh` detects a running NPM container and, if you confirm, generates `/opt/anouma/docker-compose.override.yml` joining its network automatically. To do it manually instead:

1. Find its network: `docker network ls`
2. Set `NPM_NETWORK=<that-name>` in `/opt/anouma/.env`
3. `cp docker-compose.override.yml.example docker-compose.override.yml` (in `/opt/anouma`), replacing `${NPM_NETWORK}`
4. `docker compose up -d`

In Nginx Proxy Manager, add a Proxy Host:

| Field | Value |
| --- | --- |
| Domain | your domain, e.g. `anouma.org` |
| Scheme | `http` |
| Forward Host | `app` (the Compose service name) |
| Forward Port | `3000` |
| **Websockets Support** | **enabled** — required for the LiveKit signal connection |

Für LiveKit legst du zusätzlich einen zweiten Proxy Host an:

| Field | Value |
| --- | --- |
| Domain | z. B. `livekit.anouma.org` |
| Scheme | `http` |
| Forward Host | der Server, auf dem LiveKit läuft |
| Forward Port | `7880` |
| **Websockets Support** | **enabled** |

In DNS muss die LiveKit-Domain auf denselben Server zeigen. Das Zertifikat
muss von einer öffentlichen CA stammen; selbst signierte Zertifikate werden
von Browsern für LiveKit nicht akzeptiert.

## WebRTC: LiveKit SFU und eingebettetes TURN

```
Client A ── WebRTC ──┐
                      ├── LiveKit SFU ── WebRTC ── Client B
Client C ── WebRTC ──┘          │
                                └── embedded TURN fallback
```

`docker-compose.yml` startet LiveKit mit Host-Networking, dem UDP-Medienbereich
`50000–60000`, dem TCP-Fallback `7881` und eingebettetem TURN/UDP auf `3478`.
Die API-Keys werden von `setup.sh` generiert und nur an den LiveKit-Container
und die serverseitige Token-Route gegeben. Für den Browser ist ausschließlich
`LIVEKIT_URL` als `wss://`-Endpoint sichtbar.

Firewall/NAT-Freigaben auf dem Server:

```text
TCP 443          LiveKit über den TLS-Reverse-Proxy
TCP 7881         LiveKit-TCP-Fallback
UDP 3478         eingebettetes TURN
UDP 50000-60000  LiveKit-Medien
```

Für genau einen parallelen kleinen Call ist kein Redis und keine GPU nötig.
Bei mehreren LiveKit-Instanzen oder deutlich höherer Last kommt Redis bzw. ein
Load-Balancer dazu.

## Environment variables

See `.env.example` for the full, commented list. `setup.sh` writes the real file to `/opt/anouma/.env` for you.

| Variable | Purpose |
| --- | --- |
| `DATABASE_URI`, `POSTGRES_*` | Postgres connection |
| `PAYLOAD_SECRET`, `MEETING_SESSION_SECRET`, `ANALYTICS_SALT_SECRET`, `CRON_SECRET` | Auto-generated, never overwritten afterwards |
| `NEXT_PUBLIC_SERVER_URL` | Public URL of the site |
| `SMTP_*` | The existing ANOUMA mail system |
| `LIVEKIT_URL`, `LIVEKIT_API_KEY`, `LIVEKIT_API_SECRET` | eigener LiveKit-SFU und serverseitige Token-Erzeugung |
| `DOCKER_NETWORK`, `NPM_NETWORK` | Docker network names |
| `BACKUP_RETENTION_DAYS` | Deploy-backup retention |
| `REGISTRY`, `REGISTRY_REPO`, `REGISTRY_USERNAME`, `REGISTRY_PASSWORD` | Where `deploy.sh` pulls the image from |
| `ANOUMA_IMAGE` | Set automatically by `deploy.sh` on every deploy — don't edit by hand |

## Persistent data

Deployments never delete data:

- **Database** — the `pgdata` named volume, independent of the `postgres` container's lifecycle.
- **Uploaded media** — the `/opt/anouma/media` bind mount, independent of the `app` container's lifecycle.
- **Backups** — `/opt/anouma/backups`.

Neither `setup.sh` nor `deploy.sh` ever runs `docker system prune`, `docker volume prune`, `docker network prune`, or `docker compose down -v`. Neither touches a container or network it doesn't own (an existing NPM install is never modified beyond optionally joining its network).

## Healthchecks

- **app**: `GET /api/health` (built into the image's `HEALTHCHECK`) — checks that the app can actually query Postgres, not just that the process is listening.
- **postgres**: `pg_isready`.

`docker compose ps` (from `/opt/anouma`) shows the app, Postgres and LiveKit services.

## Security

- `anouma-deploy` has **no sudo rights at all** and **no password** — the only way in is its dedicated SSH key.
- That SSH key is restricted with `restrict,command="/opt/anouma/deploy.sh"` in `authorized_keys`: whatever command an SSH client requests is ignored and `deploy.sh` runs instead (the client's actual request only reaches it via `$SSH_ORIGINAL_COMMAND`, which `deploy.sh` validates against a strict `deploy vX.Y.Z` pattern before doing anything). No arbitrary shell access is possible through this key, even if it leaks.
- `anouma-deploy` **is** a member of the `docker` group, because running `docker compose` requires it — and Docker-group membership is well known to be effectively root-equivalent (a container can bind-mount the host filesystem). This is a deliberate, documented trade-off: the blast radius is contained by the two points above (no interactive access, and the only reachable code path is the fixed `deploy.sh` logic), not eliminated. For a stricter setup, consider rootless Docker or a dedicated deployment tool with finer-grained Docker API ACLs — out of scope here.
- `.env` and the deploy SSH private key are `chmod 600`.
- Secrets are never committed, never logged, and never printed more than once (`setup.sh` shows the private key only the first time it's generated; on a later run it prints "Existing deployment key found." instead).
- `REGISTRY_PASSWORD`/`SMTP_PASSWORD`/etc. are masked (`********`) in `setup.sh`'s configuration summary — only the one-time Gitea-secrets block shows real values, since that block exists specifically for you to copy them into Gitea.

## Troubleshooting

| Symptom | Check |
| --- | --- |
| `setup.sh` fails at "Datenbank wurde nicht rechtzeitig healthy" | `docker compose logs postgres` (from `/opt/anouma`) — usually a bad `POSTGRES_PASSWORD`/`DATABASE_URI` mismatch if you hand-edited `.env` |
| Release workflow fails at "Pull the tested image" | The tagged commit was never pushed to `main`, or `main`'s CI/build-image run for it hasn't finished yet — push to `main`, wait for CI to go green, then tag |
| Release workflow fails at "Deploy to production" | Check the Gitea secrets are all set correctly, and that the server's SSH port is reachable from the runner |
| App container unhealthy after a deploy | `ssh` directly to the server (not via the restricted key) and run `docker compose logs app` from `/opt/anouma` |
| Video calls connect but no audio/video | Check LiveKit logs, the UDP 3478/50000–60000 firewall rules and the public `LIVEKIT_URL` |
| Browser cannot connect to LiveKit | Check the LiveKit proxy host, trusted TLS certificate and that Websockets Support is enabled |
| Need to redeploy the same version | `git tag -f vX.Y.Z && git push -f origin vX.Y.Z`, or push a new patch tag |
