Description

Sync the following docker repo
feed: https://quay.io/
upstream_name: openshift-release-dev/ocp-release

Pulp Crane

Check out the following output when syncing v1 content

$ curl --head -L https://<fqdn>:5000/v2/default_organization-custom-ocp/manifests/4.0.0-0

Now compare it to the same in quay

Notice how content-type is set to application/vnd.docker.distribution.manifest.v1+prettyjws in the case of quay, while its blank for pulp-crane.

This causes issues in clients pulling this information.

Revision 596ba78f View on GitHub
Added by bherring 7 months ago

The Docker v2 was not exposing the correct data for Content-Type.

The lack of information was causing issues with clients pulling
information from Crane.

Adding tests using standard `DOCKER` test libraries to ensure `Content-Type`
for any of the tags returns the appropriate information.
