Someone has hinted to me that there may be compatibility issues with docker-py > 1.4 and docker < 1.9 that may be causing this bug. Asking for info from the interested party.

Hey Dusty,

This has been fixed upstream with https://github.com/projectatomic/atomic/commit/ff44c6a9496d3b2ba8189170e30ae2e93fee9eb4 .  

The problem in the current packages is as follows:

< docker-1.8 is incompatible with python-docker-py > 1.4 as this will throw a docker/docker-client API error which was being masked by a generic docker error.

If you use docker-py-1.4 with docker-1.8 and atomic-1.8, the API error disappears but reveals an import error for a new error class in docker-py called NotFound (within verify.py) This compatibility issue was supposed to be handled via rpm deps but was missed.

So, if you choose to use docker-1.8, python-docker-py-1.6+, and atomic upstream master, everything will work.

In the above comment, I mean so say, docker-1.9+, python-docker-py-1.6+ and atomic upstream.

Fixed in atomic-1.10

I gave a try on RHEL7 system w/ atomic-1.10.5-3.el7.x86_64, docker-1.10.3-40.el7.x86_64 and python-docker-py-1.7.2-1.el7.noarch, atomic info works well.

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)

# atomic info registry.access.redhat.com/rhel7:latest
Image Name: registry.access.redhat.com/rhel7:latest

But atomic info doesn't work on RHAH 7.2.5, need I file a new bug? or waiting for new rhel-atomic-cloud building.

NOTE: docker search can find rhel7 in registry.access.redhat.com repo.

Does atomic info other non RHEL distributions work?  I think the problem might be the lack of support for V2 registries on the Red Hat site.

atomic info works well on RHEL7 system, so move the bug to verified status.
