Running with persistence

Local directories / External Configuration

Alternatively you can use volumes to make the changes persistent and change the configuration.

mkdir -p /srv/mqtt/config/
mkdir -p /srv/mqtt/data/
mkdir -p /srv/mqtt/log/
# place your mosquitto.conf 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

# Copy the files from the config directory of this project
# into /src/mqtt/config. Change them as needed for your
# particular needs.

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 toke/mosquitto

Volumes: /mqtt/config, /mqtt/data and /mqtt/log

Docker Volumes for persistence

Using Docker Volumes for persistence.

Create a named volume:

docker volume create --name mosquitto_data

Now it can be attached to docker by using -v mosquitto_data:/mqtt/data in the Example above. 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).
