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) and authentication. The default user is mosquitto/password. When authentication is activate also make sure you change the ip address in the mosquito.conf listener 1883 192.168.0.16 to your ip address\range, which can accesss mosquitto.

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

docker-compose restart

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

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
