I have an OpenHAB container and a Mosquitto container; what is the best way to restart the OpenHAB if Mosquitto is updated? Upon restarting or updating the Mosquitto, the OpenHAB (and home assistant) do not reconnect to the MQTT

  • Why do you think you need to restart the openhab container? Any MQTT clients should just reconnect when the broker restarts, show long have you left it? – hardillb Oct 17 '22 at 07:18
  • And have you raised issues with the OpenHAB/HA projects about the fact they don't reconnect? – hardillb Oct 17 '22 at 10:35
  • the problem happends when i update de mqtt brocker docker, all the HA/OH was disconnect, when i restart both everything was back online – Fernando Benavides Oct 20 '22 at 03:03

It is better to set a healthcheck for your failing containers. So, in the case that the mosquitto server is updated and they fail to connect, they can restart. For example:

version: '3.4'
services:
  web:
    image: very-simple-web
    build:
      context: ./
      dockerfile: Dockerfile
    restart: unless-stopped
    ports:
      - "80:80"
    healthcheck:
      test: curl --fail http://localhost || exit 1
      interval: 60s
      retries: 5
      start_period: 20s
      timeout: 10s

In this case very-simple-web, will fail if a request to http://localhost and restart until the healtcheck succeeds. So, you should add healthchecks for openhab and home assistant

  • the problem is that they dont fail, they keep running but the openhab and home assistant dont connect to the mqtt – Fernando Benavides Oct 17 '22 at 03:57
  • So you want them to fail in the case that they are not connected to the mqtt. So they will restart and reconnect to the mqtt – paltaa Oct 17 '22 at 13:45
