             Summary: Support pulling Docker images with V2 Schema 2 image manifest
                 Key: MESOS-6934
                 URL: https://issues.apache.org/jira/browse/MESOS-6934
             Project: Mesos
          Issue Type: Improvement
          Components: containerization
            Reporter: Ilya Pronin
            Assignee: Ilya Pronin


MESOS-3505 added support for pulling Docker images by their digest to the Mesos Containerizer provisioner. However currently it only works with images that were pushed with Docker 1.9 and older or with Registry 2.2.1 and older. Newer versions use Schema 2 manifests by default. Because of CAS constraints the registry does not convert those manifests on-the-fly to Schema 1 when they are being pulled by digest.

Compatibility details are documented here: https://docs.docker.com/registry/compatibility/
Image Manifest V2, Schema 2 is documented here: https://docs.docker.com/registry/spec/manifest-v2-2/
