Mosquitto MQTT Broker on Docker Image

docker-mosquitto

Mosquitto MQTT Broker on Docker Image.

Version

mosquitto v1.4

This version implement MQTT over WebSocket. You can use an MQTT JavaScript library to connect, like Paho: http://eclipse.org/paho/clients/js/

Build

Use the provide Makefile to build the image.

Build the Mosquitto docker image

$ sudo make

You can specify your repository and tag by

$ sudo make REPOSITORY=my_own_repo/mqtt TAG=v1.4

Default for REPOSITORY is jllopis/mosquitto (should change this) and for TAG is latest.

Persistence and Configuration

If you want to use persistence for the container or just use a custom config file you must use VOLUMES from your host or better, data only containers.

The container has three directories that you can use:

• /etc/mosquitto to store mosquitto configuration files
• /etc/mosquitto.d to store additional configuration files that will be loaded after /etc/mosquitto/mosquitto.conf
• /var/lib/mosquitto to persist the database

The logger outputs to stderr by default.

See the following examples for some guidance:

Mapping host directories

$ sudo docker run -ti \
  -v /tmp/mosquitto/etc/mosquitto:/etc/mosquitto \
  -v /tmp/mosquitto/etc/mosquitto.d:/etc/mosquitto.d \
  -v /tmp/mosquitto/var/lib/mosquitto:/var/lib/mosquitto 
  --name mqtt \
  -p 1883:1883 \
  -p 9883:9883 \
  jllopis/mosquitto

Data Only Containers

You must create a container to hold the directories first:

$ sudo docker run -d -v /etc/mosquitto -v /etc/mosquitto.d -v /var/lib/mosquitto --name mqtt_data busybox /bin/true

and then just use VOLUMES_FROM in your container:

$ sudo docker run -ti \
  --volumes-from mqtt_data \
  --name mqtt \
  -p 1883:1883 \
  -p 9883:9883 \
  jllopis/mosquitto
