A simple Mosquitto Docker Compose template

Simple Mosquitto broker

This is a simple Mosquitto broker to to quickly initialize projects requiring an MQTT broker. The config file is in the folder config/mosquitto.conf.

By default we activated the log and data persistance (respectively in log and data folder). The authentication can be activated if needed.

How to use

To start the container, just :

docker-compose up -d

The Mosquitto broker is now available on localhost. You can test it easily (require Mosquitto client):

| In one shell:

mosquitto_sub -h localhost -t "sensor/temperature"

| In a second shell:

mosquitto_pub -h localhost -t sensor/temperature -m 23

Enabling authentication

In the config file, just uncomment the Authentication part and then restart the container. The default user is admin/password.

You always have to restart if you want the modification to be taken in account:

docker-compose restart

Change user password / create a new user:

docker-compose exec mosquitto mosquitto_passwd -b /mosquitto/config/password.txt user password

Delete user:

docker-compose exec mosquitto mosquitto_passwd -D /mosquitto/config/password.txt user
