Eclipse Mosquitto Docker Image

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

Mount Points

A docker mount point has been created in the image to be used for configuration.

/mosquitto/config

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

/mosquitto/data
/mosquitto/log

User/Group

The image runs mosquitto under the mosquitto user and group, which are created with a uid and gid of 1883.

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>

💥 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, for example:

docker run -it -p 1883:1883 -p 8080:8080 -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.
