Mqtt support

[DeltaTango69]

Describe the bug

Gemini or chatgpt gives me following configuration for MQTT messages for example for Homeassistant.

version: '3'
services:
  watchtower:
    image: containrrr/watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - WATCHTOWER_NOTIFICATION_MQTT_ENABLE=true
      - WATCHTOWER_NOTIFICATION_MQTT_BROKER_HOST=DEINE_MQTT_BROKER_IP
      - WATCHTOWER_NOTIFICATION_MQTT_BROKER_PORT=1883 # Standard MQTT Port, ggf. anpassen
      - WATCHTOWER_NOTIFICATION_MQTT_BROKER_USERNAME=DEIN_MQTT_USERNAME # Optional
      - WATCHTOWER_NOTIFICATION_MQTT_BROKER_PASSWORD=DEIN_MQTT_PASSWORT # Optional
      - WATCHTOWER_NOTIFICATION_MQTT_TOPIC=watchtower/events
      - WATCHTOWER_NOTIFICATION_MQTT_CLIENT_ID=watchtower-$(hostname) # Optional, erzeugt eine eindeutige Client-ID
      - WATCHTOWER_NOTIFICATION_MQTT_TLS_ENABLE=false # Optional, für TLS-Verschlüsselung
      # - WATCHTOWER_NOTIFICATION_MQTT_TLS_CA_CERTS=/path/to/ca.crt # Optional, Pfad zum CA-Zertifikat
    command: deine_container_namen_oder_alle --interval 300 # Beispiel: alle 5 Minuten prüfen
    restart: unless-stopped

But I find no official support for that. Also it is not working?! Was this implemented before and not more yet?

Steps to reproduce

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Watchtower doesn't support MQTT directly, but it does support notifications through Shoutrrr. In theory, MQTT support could be added there via a pull request: containrrr/shoutrrr. However, the project appears to be mostly inactive, so it might be unlikely that such a feature would be accepted or maintained.

Maybe give https://github.com/nicholas-fedor/watchtower a try? It's very active maintained.
