How to clean up none docker images

You might create several <none> docker images during building a docker container. So cleaning up would be good for your local development environment because they might take your local storage.There are two ways that you can clean up.

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

If you are using Docker API(higher than 1.25) and you can use prune command.

docker image prune

By the way be careful to type it. If you add -a option it will remove all your Docker images.
