## Uebersicht

Der Night Scheduler ermoeglicht die automatische Nachtabschaltung der Docker-Services:

## Konfiguration

### Config-Format (night-mode.json)

```json
{
  "enabled": true,
  "shutdown_time": "22:00",
  "startup_time": "06:00",
  "last_action": "startup",
  "last_action_time": "2026-02-09T06:00:00",
  "excluded_services": ["night-scheduler", "nginx"]
}
```

### Umgebungsvariablen

| Variable | Default | Beschreibung |
|----------|---------|--------------|
| `COMPOSE_PROJECT_NAME` | `breakpilot-pwa` | Docker Compose Projektname |

---

## Ausgeschlossene Services

Diese Services werden NICHT gestoppt:

1. **night-scheduler** - Muss laufen, um Services zu starten
2. **nginx** - Optional, fuer HTTPS-Zugriff

Weitere Services koennen ueber die Konfiguration ausgeschlossen werden.

---

## Docker Compose Integration

```yaml
night-scheduler:
  build: ./night-scheduler
  container_name: breakpilot-pwa-night-scheduler
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - ./night-scheduler/config:/config
    - ./docker-compose.yml:/app/docker-compose.yml:ro
  environment:
    - COMPOSE_PROJECT_NAME=breakpilot-pwa
  ports:
    - "8096:8096"
  networks:
    - breakpilot-pwa-network
  restart: unless-stopped
```

---

## Tests ausfuehren

```bash
# Im Container
docker exec -it breakpilot-pwa-night-scheduler pytest -v

# Lokal (mit Dependencies)
cd night-scheduler
pip install -r requirements.txt
pytest -v tests/
```

---

## Deployment

```bash
# 1. Dateien synchronisieren
rsync -avz night-scheduler/ macmini:.../night-scheduler/

# 2. Container bauen
ssh macmini "docker compose -f .../docker-compose.yml build --no-cache night-scheduler"

# 3. Container starten
ssh macmini "docker compose -f .../docker-compose.yml up -d night-scheduler"

# 4. Testen
curl http://macmini:8096/health
curl http://macmini:8096/api/night-mode
```

---

## Troubleshooting

### Problem: Services werden nicht gestoppt/gestartet

1. Pruefen ob Docker Socket gemountet ist:
   ```bash
   docker exec breakpilot-pwa-night-scheduler ls -la /var/run/docker.sock
   ```

2. Pruefen ob docker compose CLI verfuegbar ist:
   ```bash
   docker exec breakpilot-pwa-night-scheduler docker compose version
   ```

3. Logs pruefen:
   ```bash
   docker logs breakpilot-pwa-night-scheduler
   ```

### Problem: Konfiguration wird nicht gespeichert

1. Pruefen ob /config beschreibbar ist:
   ```bash
   docker exec breakpilot-pwa-night-scheduler touch /config/test
   ```

2. Volume-Mount pruefen in docker-compose.yml

### Problem: API nicht erreichbar

1. Container-Status pruefen:
   ```bash
   docker ps | grep night-scheduler
   ```

2. Health-Check pruefen:
   ```bash
   curl http://localhost:8096/health
   ```

---

## Sicherheitshinweise

- Der Container benoetigt Zugriff auf den Docker Socket
- Nur interne Services koennen gestoppt/gestartet werden
- Keine Authentifizierung (internes Netzwerk)
- Keine sensitiven Daten in der Konfiguration
