## 1. Geteilte Infrastruktur einrichten (einmalig)

### Verzeichnisse anlegen

```bash
sudo mkdir -p /volume2/docker/shared/pgdata
```

### docker-compose.yml kopieren

```bash
sudo cp infra/docker-compose.yml /volume2/docker/shared/docker-compose.yml
```

### .env anlegen

Datei `/volume2/docker/shared/.env`:

```env
POSTGRES_PASSWORD=<sicheres-passwort>
```

### Starten

```bash
cd /volume2/docker/shared
sudo docker compose up -d
```

### Datenbank & User anlegen

```bash
sudo docker exec -it shared-postgres-1 psql -U postgres
```

```sql
CREATE DATABASE pamietnik;
CREATE USER pamietnik WITH PASSWORD 'deinPasswort';
GRANT ALL PRIVILEGES ON DATABASE pamietnik TO pamietnik;
\q
```

---

## 2. Pamietnik-Deployment einrichten (einmalig)

```bash
sudo mkdir -p /volume2/docker/pamietnik/uploads
```

Datei `/volume2/docker/pamietnik/.env`:

```env
DB_PASSWORD=<passwort-von-oben>
APP_PORT=9050
```

---

## 3. Gitea CI/CD einrichten (einmalig)

### act_runner starten

Token holen: **Gitea → Site-Administration → Actions → Runner → Runner erstellen**

```bash
sudo docker run -d \
  --name gitea-runner \
  --restart unless-stopped \
  --network host \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /volume2/docker/gitea-runner:/data \
  -e GITEA_INSTANCE_URL=http://localhost:3000 \
  -e GITEA_RUNNER_REGISTRATION_TOKEN=<token-aus-gitea> \
  -e GITEA_RUNNER_NAME=nas-runner \
  -e GITEA_RUNNER_LABELS=self-hosted,linux,amd64 \
  gitea/act_runner:latest
```

### Gitea Secrets & Variables setzen

**Repository → Einstellungen → Actions → Secrets:**

| Secret | Wert |
|--------|------|
| `DB_PASSWORD` | Passwort des `pamietnik` DB-Users |
| `DEPLOY_DIR` | `/volume2/docker/pamietnik` |

**Repository → Einstellungen → Actions → Variables:**

| Variable | Wert |
|----------|------|
| `DB_USER` | `pamietnik` |
| `DB_NAME` | `pamietnik` |
| `APP_PORT` | `9050` |

---

## 4. Dienste & URLs

| Dienst | URL |
|--------|-----|
| Pamietnik App | `http://<NAS-IP>:9050` |
| PostgreSQL | `psql -h <NAS-IP> -p 5433 -U pamietnik -d pamietnik` |

---

## 5. Neues Projekt hinzufügen

```bash
sudo docker exec -it shared-postgres-1 psql -U postgres
```

```sql
CREATE DATABASE neuprojekt;
CREATE USER neuprojekt WITH PASSWORD 'passwort';
GRANT ALL PRIVILEGES ON DATABASE neuprojekt TO neuprojekt;
\q
```

In `docker-compose.yml` des neuen Projekts:
```yaml
extra_hosts:
  - "host-gateway:host-gateway"
environment:
  DATABASE_URL: postgres://neuprojekt:passwort@host-gateway:5433/neuprojekt
```

---

## 6. Wartung

```bash
# Logs
sudo docker compose -f /volume2/docker/shared/docker-compose.yml logs -f
sudo docker compose -f /volume2/docker/pamietnik/docker-compose.yml logs -f api

# Backup
sudo docker exec shared-postgres-1 pg_dump -U postgres pamietnik \
  > /volume2/docker/shared/backup_$(date +%Y%m%d).sql

# Stoppen
sudo docker compose -f /volume2/docker/shared/docker-compose.yml down
sudo docker compose -f /volume2/docker/pamietnik/docker-compose.yml down
```
