Docker images/containers cleaning

1- Delete all containers

docker ps -q -a | xargs docker rm

-q prints only the container IDs -a prints all containers

Use xargs to issue a remove container command for each container ID

2- Delete all untagged images

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

Awk must use a single quote otherwise does not recognize the space seperators.
