Hi,
I just got off a half hour discussion with the pulp guys for the CentOS Container Pipeline registry story.
1. docker save x.tar produces a v1 tarball and not a v2 tarball 2. This tarball doesnt contain metadata such as tags and so on. 3. docker pull from docker 1.6 assumes the registry being pulled from is a v2 registry 4. v1 registry has been depricated. 5. Currently, the only way to get a v2 repo into pulp or any other registry is to first push it to docker registry and then sync our registry to it.
I seriously am beginning to hate docker.
