Simple Mosquitto broker

This is a simple Mosquitto broker to quickly initialize projects requiring an MQTT broker.

Prerequisite

At first startup, you need to setup the project:

make setup-project

Then, and for other startup, you just have to run:

make up

Find other make helper command in the Makefile

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

The config file is in the file mosquito.conf

By default we activated the log and data persistance (logs are in the log folder, and data are stored in a docker volume).

In the config file, set the value allow_anonymous to false, then uncomment the last line (password_file) and finaly restart the container.

The default user is admin/password.

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

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