Docker remove all cotainers except for with given name (mvn_repository) and untagged images

drm.sh

#!/bin/bash -eux
E=$(docker ps -aq --filter "name=mvn_repository")
docker ps -aq | grep -v ${E:-lookup_failed} | xargs docker rm -f
docker images | sed -E 's/ +/ /g' | grep "^<none> <none>" | cut -d ' ' -f 3 | xargs docker rmi -f

might need -f at the end
