Pulp 2.14 added support for docker manifest lists (https://docs.docker.com/registry/spec/manifest-v2-2/#manifest-list) as part of https://pulp.plan.io/issues/2384

From my general understanding manifest lists are meant for multi architecture containers. For example in a checkout a busybox repo. Notice that the tag 'glibc' (having schema 1 and 2 versions) points to a manifest list:

 
> db.units_docker_tag.find({'name':'glibc'})
