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 commands below need to be 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


sudo service docker restart
