Epic Goal

• Add support of manifest lists (Docker schema 2 and OCI images).

Why is this important?

• Customers may want to push manifest list into the integrated registry or to leverage pull-through for manifest lists.
• Today OpenShift imports a manifest for the current architecture when it is requested to import a manifest list. As the manifest itself is not imported, clients that rely on digests cannot use this image.

Scenarios

1. Mirroring manifest lists into the integrated registry (either via pushing them or via importing them).

Acceptance Criteria

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.
• ...
