Docker and MQTT (Mosquito)

My Mosquito implementation is not heavily modified.  In fact, it's so simple, I could do a :

docker run -d ---name mosquitto -p 1883:1883 eclipse-mosquitto:2

This would be just fine.  However, I want my docker image to restart after reboots, and I'm too lazy to go about it any other way than a docker-compose.yml :

# docker-compose.yml - Mosquitto MQTT broker
services:
  mosquitto:
    image: eclipse-mosquitto:2
    container_name: mqtt
    ports:
      # Standard MQTT protocol
      - "1883:1883"
      # MQTT over WebSocket
      - "9001:9001"
    #volumes:
      # Mount configuration directory
      #- ./config:/mosquitto/config
      # Persist message data
      #- ./data:/mosquitto/data
      # Persist log files
      #- ./log:/mosquitto/log
    restart: unless-stopped

Note the entire "volumes" section has been commented out.  I started to add it, and realized I didn't care about persisting message or log data, nor was I running a custom configuration.  So, I left it out.

Then, start it up in the usual fashion with a :

docker compose up -d

And off you go!
