raphcalvignac/rpi-mosquitto repository overview

⁠rpi-mosquitto

Docker image for mosquitto adapted to Rpi based on resin/rpi-raspbian:jessie-20160831 and toke/docker-mosquitto

⁠Run

Run the container without configuration nor persistence: Exposes Port 1883 (MQTT) 9001 (Websocket MQTT)

docker run -ti -p 1883:1883 -p 9001:9001 --name mqtt raphcalvignac/rpi-mosquitto:0.3

⁠Run with data persistence and configuration

⁠Using local directories

Create host directotries to be used as data volumes for configuration persistence:

mkdir -p /srv/mqtt/config/
mkdir -p /srv/mqtt/data/
mkdir -p /srv/mqtt/log/

Copy the mosquitto.conf file from config directory (https://github.com/toke/docker-mosquitto⁠) in /srv/mqtt/config/

NOTE: You have to change the permissions of the directories to allow the user to read/write to data and log and read from config directory For TESTING purposes you can use chmod -R 777 /srv/mqtt/* Better use "-u" with a valid user id on your docker host

Run command

docker run -ti -p 1883:1883 -p 9001:9001 -v /srv/mqtt/config:/mqtt/config:ro -v /srv/mqtt/log:/mqtt/log -v /srv/mqtt/data/:/mqtt/data/ --name mqtt raphcalvignac/rpi-mosquitto:0.3

⁠Using docker volumes

Create a named volume:

docker volume create --name mosquitto_data

Now it can be attached to docker by using -v mosquitto_data:/mqtt/data. Be aware that the permissions within the volumes are most likely too restrictive.

⁠Start with systemd

As an example this how you run the container with systemd. The example uses a docker volume named mosquitto_data (see above).
