How to use this image


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



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.
