View docker files on Ubuntu
Docker files (images, containers, etc) are usually stored under /var/lib/docker on Ubuntu.
Delete all Images
$ docker rmi -f $(docker images --quiet)
Or, alternatively, using sudo:
$ sudo docker rmi -f $(sudo docker images --quiet)
Delete old Images
Unused images are called dangling images:
$ docker rmi $(docker images --quiet --filter "dangling=true")
Delete all Containers
$ docker rm $(docker ps --all --quiet)
Delete stopped containers
$ docker rm $(docker ps --quiet --filter status=exited)
Delete old volumes
Similarly, unused volumes are called dangling volumes.
Use docker volume prune
Example:
$ docker volume prune
WARNING! This will remove all local volumes not used by at least one container.
