Kubernetes secret for registry access
OpenShift needs credentials to be able to pull the container images from the Gitlab container registry. The registry secret is a little trickier because of the unique docker configuration required.
Back in Gitlab, copy the contents of the staging-cluster/registry-secret.yaml file to your clipboard. Make sure you copy the version from the staging branch and that you copy the entire file.
Switch back to the OpenShift console. Select the + button in the upper right corner. Paste the contents of the secret and select the Create button on the bottom of the page.
