Eclipse Mosquitto Docker Image

Containers built with this Dockerfile build as source from published tarballs.

Mount Points

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

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

Running without a configuration file

Mosquitto 2.0 requires you to configure listeners and authentication before it will allow connections from anything other than the loopback interface. In the context of a container, this means you would normally need to provide a configuration file with your settings.

If you wish to run mosquitto without any authentication, and without setting any other configuration options, you can do so by using a configuration provided in the container for this purpose:

docker run -it -p 1883:1883 eclipse-mosquitto:<version> mosquitto -c /mosquitto-no-auth.conf

Configuration

When creating a container from 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 -v <absolute-path-to-configuration-file>:/mosquitto/config/mosquitto.conf eclipse-mosquitto:<version>

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: For any volume used, the data will be persistent between containers.

Build

Build and tag the docker image for a specific version:

docker build -t eclipse-mosquitto:<version> --build-arg VERSION="<version>" .

Run

Run a container using the new image:

docker run -it -p 1883:1883 -v <path-to-configuration-file>:/mosquitto/config/mosquitto.conf -v /mosquitto/data -v /mosquitto/log eclipse-mosquitto:<version>

💥 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.
