When you are building all kinds of docker images, you may end up with a lot of untagged images, volumes. A trick I used in my own projects is a bash function like this.

# docker clean up, remove all stopped containers and untagged images

# https://github.com/chadoe/docker-cleanup-volumes
# https://www.calazan.com/docker-cleanup-commands/
docker-cleanup() {
    docker rm $(docker ps -a -q);
    docker rmi $(docker images -q -f dangling=true);
    docker volume rm $(docker volume ls -qf dangling=true)
}

Most of the times, just removing the stopped containers is good enough. But it's nice to have something to clean up locally.
