A container’s thin writable layer is stored in a directory under /var/lib/docker/aufs/diff/. With Docker 1.10 and higher, container IDs no longer correspond to directory names.
When I was using Docker 1.9.0, the files in a container are located in /var/lib/docker/aufs/diff/“container-id”. But today I found out that Container-ID is no longer used after upgrading the version to 1.10.
In my project, I automatically need to locate files that used in a Docker container.
What corresponds to directory names under /var/lib/docker/aufs/diff?
