I've tried the following:

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

And the following:

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

Get the following error:

docker: "rmi" requires a minimum of 1 argument.
See 'docker rmi --help'.

Usage:  docker rmi [OPTIONS] IMAGE [IMAGE...]

Remove one or more images

Answer 1

According to the docker documentation you can list only untagged (dangling) images with

$ docker images -f "dangling=true"

and redirect them to docker rmi command like that:

$ docker rmi $(docker images -f "dangling=true" -q) --force

Notice -q param thats only show numeric IDs of containers.

Answer 2

Remove images which have none as the repository name using the following:

docker rmi $(docker images | grep "^<none" | awk '{print $3}')

Remove images which have none tag or repository name:

docker rmi $(docker images | grep "none" | awk '{print $3}')

Answer 3

This is an extension of tansadio's answer:

If you are getting following error:

Error response from daemon: conflict: unable to delete <> (must be forced) - image is being used by stopped container <>

You can force it with --force:

docker images | grep none | awk '{ print $3; }' | xargs docker rmi --force
