Remove all unused docker data including volumes, images, network, etc in one command:

docker system prune [OPTIONS]

To remove all unused data:

docker system prune -a

The command will give a warning and then deletes all unused data from docker.

WARNING! This will remove:
     - all stopped containers
     - all volumes not used by at least one container
     - all networks not used by at least one container
     - all images without at least one container associated to them
