Newbie help request - setting up mosquitto

Configuration
3

Assuming you’re sensible enough to be using a Docker Compose file, you can “install” Mosquitto with the following addition to your compose file:

  mosquitto:
    container_name: mosquitto
    image: eclipse-mosquitto:2
    restart: unless-stopped
    ports:
      - "1883:1883/tcp"
    volumes:
      - /data/mosquitto/config:/mosquitto/config
      - /data/mosquitto/data:/mosquitto/data
      - /data/mosquitto/log:/mosquitto/log
    healthcheck:
      test: ["CMD", "mosquitto_sub", "-u", "test", "-P", "test_user_password", "-h", "localhost", "-t", "$$SYS/broker/uptime", "-i", "docker_health_check", "-C", "1"]
      interval: 1m
      timeout: 10s
      retries: 3

Then in /data/mosquitto/config you’ll want to create a config file. Mine for instance looks like:

persistence true
persistence_location /mosquitto/data/

password_file /mosquitto/config/pwfile
allow_anonymous false

log_dest file /mosquitto/log/mosquitto.log

listener 1883

And once you start the container you can create a user in mosquitto with a command like this:

docker compose exec mosquitto mosquitto_passwd -b /mosquitto/config/pwfile test test_user_password

Once you’ve created a user you need to restart mosquitto (restart the container)
