Add persistent tags to docker image #110
Description
My system crashed and I lost all my containers. After rebuilding my setup maria db complained that it could not upgrade to a newer version after a crash. The upgrade to a newer version happened because "latest" was pulled. However the version I needed after the crash, was "10.4". However there is no tag for older images. It would be nice to have this, so that one can use a fixed version in his/her docker-compose and be on the safe side.
