How do I push an image to the OpenShift Docker registry if it is not exposed outside the cluster?
Login to a member node
Get on a machine that has docker and participates in the cluster SDN or can somehow access that network. (eg. 172.30.0.0/16)
Get the IP of the registry
oc get svc docker-registry -n default --template "{{ .spec.clusterIP }}"
SVC_REGISTRY=$(oc get svc docker-registry -n default --template "{{ .spec.clusterIP }}")
Get a token for your session
oc whoami -t
r4bjk9MrFcWz8SjR688zvbAbwnI1yoqNbtdhN1sMaeo
TOKEN=$(oc whoami -t)
Login to the docker registry
docker login -u $(oc whoami) -p $TOKEN $SVC_REGISTRY:5000
Commit the container and / or tag the image
docker commit <container_id> $SVC_REGISTRY:5000/project/image:tag
Push the tagged image
docker push $SVC_REGISTRY:5000/project/image:tag
