Docker image cleanup

Running docker frequently can lead to mysteriously disappearing space. I kid, its not mysterious. Each image builds a layer which in turn eats up space. Logical but PITA!

Put this in your .bashrc or run it as cron on your docker host to clean up.


docker rm -v $(docker ps -a -q -f status=exited)
docker rmi $(docker images -f “dangling=true” -q)


or do it in one alias (use at your own discretion)


alias docker_janitor='docker rm -v $(docker ps -a -q -f status=exited);docker rmi $(docker images -f “dangling=true” -q)'


sounds too easy..

ciao!
