hello? @stevvooe
LGTM
@tianon What do we need to do to get this updated?
Once this is merged, that'd be a PR to https://github.com/docker-library/official-images/blob/master/library/registry, which I'd be happy to make for you if you'd like. :+1:
(Probably worth considering whether 2.5.x is still actually supported and update to the new RFC 2822-based format while we're at it.)
@tianon I'm OK, thanks for making that PR.
BTW @stevvooe , I have another PR for registry, would you mind take a look? https://github.com/docker/distribution/pull/2465
