Docker provides a single command that will clean up any resources that are dangling (not associated with a container):

docker system prune

To additionally remove any stopped containers and all unused images (not just dangling images), add the -a flag to the command:

docker system prune -a

Remove all the images

docker rmi $(docker images -a -q)

Remove all exited containers

docker rm $(docker ps -a -f status=exited -q)

Stop and remove all the containers

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)
