Location of Image Files
The contents of the /var/lib/docker directory vary depending on the driver Docker is using for storage. By default this will be aufs but can fall back to overlay, overlay2, btrfs, devicemapper or zfs depending on your kernel support. In most places this will be aufs but the RedHats went with devicemapper.
Basic Commands
All prepended by "sudo docker":
- images
- rmi (or rmi -f if simple image delete fails)
- ps -a
- container ls
The docker system prune command will remove all stopped containers, all dangling images, and all unused networks:
- system prune
Restart
