I run into this pretty frequently with Docker on Mac OS X. Passing the `--rm` flag helps, but for cleaning up old/unused containers, I usually set these two commands on a cron:

    # Remove un-tagged or un-named images
    for im in $(docker images | awk '/<none>/ { print $3 }'); do docker rmi $im; done

    # Remove stopped containers
    docker rm $(docker ps -a -q)

You can also do this:

    docker rmi $(docker images -q -f dangling=true

You might consider doing the same with volumes:

    docker volume rm $(docker volume ls -q -f dangling=true)

But be careful with the volume one. I'd read the documentation around volumes first and see if you're deleting what you want to. :)
