Docker image cleaner

The long missing command to clean up all docker images that are not used by any container.

Usage

This command is available as docker image bobrik/image-cleaner:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock bobrik/image-cleaner

Add -dry-run to the end if you want to see what is going to be deleted.

If you want to keep some images, use -exclude image:tag[,image:tag] flag.
