Clean out your Docker images, containers and volumes

Cleaning up containers
Kill all running containers

> docker kill $(docker ps -q)

Delete all stopped containers

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

Cleaning up images
Delete an image

> docker rmi <image name>

Delete all 'untagged/dangling' images

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

Delete all images

> docker rmi $(docker images -q)

Cleaning up volumnes
Once a volume is not longer associated with a container, it is considered 'dangling'

> docker volume rm $(docker volume ls -f dangling=true -q)
