Eclipse Mosquitto is an open source implementation of a server for versions 5, 3.1.1, and 3.1 of the MQTT protocol. Main homepages: http://mosquitto.org/

Three directories have been created in the image to be used for configuration, persistent storage and logs.

/mosquitto/config
/mosquitto/data
/mosquitto/log

When running the image, the default configuration values are used. To use a custom configuration file, mount a local configuration file to /mosquitto/config/mosquitto.conf

$ docker run -it -p 1883:1883 -p 9001:9001 -v mosquitto.conf:/mosquitto/config/mosquitto.conf eclipse-mosquitto

Configuration can be changed to:

• persist data to /mosquitto/data
• log to /mosquitto/log/mosquitto.log

i.e. add the following to mosquitto.conf:

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log

Note: If a volume is used, the data will persist between containers.

Run a container using the new image:

$ docker run -it -p 1883:1883 -p 9001:9001 -v mosquitto.conf:/mosquitto/config/mosquitto.conf -v /mosquitto/data -v /mosquitto/log eclipse-mosquitto

Note: if the mosquitto configuration (mosquitto.conf) was modified to use non-default ports, the docker run command will need to be updated to expose the ports that have been configured.
