Pushing to an OpenShift registry

How to setup an OpenShift registry

  • Create registry with oadm
oadm registry --latest-images --create \
              --credentials=/var/lib/openshift/openshift.local.config/master/openshift-registry.kubeconfig
  • Create route (optional, alternatively you can use also the internal ip of the registry service later)
