I recently came across trying to create a registry using the step located in the docs:
oadm registry --config=/etc/openshift/master/admin.kubeconfig
--credentials=/etc/openshift/master/openshift-registry.kubeconfig
--images='registry.access.redhat.com/openshift3/ose-${component}:${version}'

The ${components/version} variables were not set resulting in my pod failing to pull image 'registry.access.redhat.com/openshift3/ose-:'.

Removing the --image parameter fixed this and pulled the docker-registry:v3.0.1.0. However, in the docs it says it a required parameter.

Are ${component}:${version} not necessary anymore? Docs may need to be updated.
