-----------------------------------

             Summary: Allow docker puller to use docker image IDs in addition to tags
                 Key: MESOS-5211
                 URL: https://issues.apache.org/jira/browse/MESOS-5211
             Project: Mesos
          Issue Type: Bug
          Components: containerization, docker
    Affects Versions: 0.28.0
            Reporter: Cody Maloney


Docker added support for a {{@<digest>}} format instead of {{:<tag>}} in 1.6. 

The {{@<digest>}} is useful because it allows reference to specific set of bits, rather than a tag (such as {{:latest}}) which can change over time.

Currently a number of code paths, such as the [Mesos Docker code|https://github.com/apache/mesos/blob/df29bf0338771c92d1b1d3848181a35429cdcf0f/src/docker/docker.cpp#L1070], the [Mesos Containerizer Docker Provisioner|https://github.com/apache/mesos/blob/df29bf0338771c92d1b1d3848181a35429cdcf0f/src/slave/containerizer/mesos/provisioner/docker/registry_puller.cpp#L206] do not support pulling / fetching docker containers by id.
