I setup openshift origin cluster 3.6 and found a problem with private registry.
Image was failed to be pulled by work node with error as below,
rpc error: code = 2 desc = unauthorized: authentication required
However, the registry works well and I also could find the image via docker-console.
I installed the cluster via "Advanced installation". It seemed insecure registry is not enabled.
How could I check what's wrong in my env?
