Where are Docker images stored on the host machine?

Question

I managed to find the containers under directory /var/lib/docker/containers, but I can\'t find the images.

What are the directories and files under

Answer 1

The images are stored in /var/lib/docker/graph//layer.

Note that images are just diffs from the parent image. The parent ID is stored with the image's metadata /var/lib/docker/graph//json.

When you docker run an image. AUFS will 'merge' all layers into one usable file system.
