----------------------------------
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/
