We should ensure that all devfiles that support deployment to an openshift cluster remind users to first oc login. These commands should be numbered sequentially too, so the call to action and sequence is obvious.

Good example:

https://github.com/redhat-developer/codeready-workspaces/blob/master/dependencies/che-devfile-registry/devfiles/04_nodejs-configmap/devfile.yaml#L42-L50

Bad example:

https://github.com/redhat-developer/codeready-workspaces/blob/master/dependencies/che-devfile-registry/devfiles/02_java-jboss-fuse/devfile.yaml#L61-L67
