Clean docker images: docker rmi $(docker images -f dangling=true -q --no-trunc)

Dangling images are just those that are not tagged. That happens if you create a new image and tag it with an already existing tag (e.g. latest).

This command won't help you clean up disk space if you build/pull images each with their own unique tags.

Docker 1.13 is shipping with cleanup commands built in.
