Example with mosquitto has Error: Connection refused

[ChocolateLoverRaj]

Docker version 27.3.1, build v27.3.1
My docker-compose.yml:

services:

  otrecorder:
    image: owntracks/recorder
    ports:
      - 8083:8083
    volumes:
      - config:/config
      - store:/store
    restart: unless-stopped
    environment:
      OTR_HOST: mosquitto

  mosquitto:
    image: eclipse-mosquitto
    ports:
      - 1883:1883
      - 8883:8883
    volumes:
      - mosquitto-data:/mosquitto/data
      - mosquitto-logs:/mosquitto/logs
      - mosquitto-conf:/mosquitto/config
    restart: unless-stopped

volumes:
  store:
  config:
  mosquitto-data:
  mosquitto-logs:
  mosquitto-conf:

Then I ran docker compose up as root and this happens:

and it keeps repeating the last 3 lines over and over.

Does the Docker with MQTT example need to be updated?

[jpmens]

can you show the content of config/mosquitto.conf ?

[jpmens]

Note in particular:

mosquitto-1   | 1730655922: Create a configuration file which defines a listener to allow remote access.
mosquitto-1   | 1730655922: For more details see https://mosquitto.org/documentation/authentication-methods/

I think you are right in that the example doesn't work. This is what I've done to seemingly make it work:

$ mkdir config
$ cat | tee config/mosquitto.conf <<EOF
listener 1883
allow_anonymous true
EOF

Note the changed mounts in the docker compose file (docker-compose-mqtt.yml)

services:

  otrecorder:
    image: owntracks/recorder
    ports:
      - 8083:8083
    volumes:
      - config:/config
      - store:/store
    restart: unless-stopped
    environment:
      OTR_HOST: mosquitto

  mosquitto:
    image: eclipse-mosquitto
    ports:
      - 1883:1883
      - 8883:8883
    volumes:
      - ./config:/mosquitto/config/:rw
      - ./data:/mosquitto/data:rw
      - ./log:/mosquitto/log:rw
    restart: unless-stopped

volumes:
  store:
  config:

$ docker compose -f docker-compose-mqtt.yml up

This definitely needs checking by somebody who knows what they're doing with docker.

[ChocolateLoverRaj]

With your changes it worked for me. Ideally the mosquitto configuration should be able to be configured in docker-compose.yml right?

[jpmens]

The path to the file can. Its content cannot, I think.
