Docker changing /var/lib/docker/aufs/diff location

Docker folder /var/lib/docker/aufs/diff grows too much and I would like to move it on an other partition. Is there a way to configure Docker to use another location for this foder?

Solution

  • There's an easy way to get the docker daemon to handle this for you.

    stop docker

    $ service docker stop

    add this line to /etc/default/docker

    # Use DOCKER_OPTS to modify the daemon startup options.
DOCKER_OPTS="-g /<new destination>/docker/"

    start docker

    $ service docker start

    verify the docker files and folders are created in the new destination

    remove /var/lib/docker

    /var/lib$ sudo rm -rf docker
