 This docker image is configured to use a MySQL database backend. The database connection can be configured using environment variables. If not specified, the image will start a mysql server internally and use it. However in this case, the data stored in the mysql database will be lost if the container is stopped/deleted. To avoid this you should mount a volume at /var/lib/mysql.
