Ok, maybe that is the issue. I can not do the docker pull referencing the sha256 hash on the node.
The docker version running on the node is docker 1.10.3, and the docker version on the machine that pushed the image is 1.12.0. Is there a potential workaround for this, or do I need to get the docker version updated on the nodes? For reference, I installed the openshift platform using the ansible advanced installation referenced in the documentation.
