docker ps -qaf status=exited | xargs docker rm
docker images -qf dangling=true | xargs docker rmi

# it would be better to use "--no-run-if-empty" option for xargs as described in https://gist.github.com/ngpestelos/4fc2e31e19f86b9cf10b#gistcomment-1769502
# but xargs does not support this option on Mac
