Description Ryan Howe 2018-12-07 16:26:59 UTC 
Document URL: 
https://docs.openshift.com/container-platform/3.11/install_config/registry/deploy_registry_existing_clusters.html

Describe the issue: 

For imagestreams to work properly REGISTRY_OPENSHIFT_SERVER_ADDR must be equal to what is set for internalRegistryHostname set in the master-config.yaml. 

imagePolicyConfig:
internalRegistryHostname: docker-registry.default.svc:5000


Information is deep in the configuration doc but should be moved to deploying existing registry doc.  
https://docs.openshift.com/container-platform/3.11/install_config/registry/extended_registry_configuration.html#setting-the-registry-hostname

# oc set env dc docker-registry REGISTRY_OPENSHIFT_SERVER_ADDR=docker-registry.default.svc:5000


Ansible installer sets this:
