You need to have the oc command installed to interact with OpenShift from the command line. This can be installed from https://github.com/openshift/origin. Docker is also required. Search online for information on how to do that.
These are the commands to ensure your system state is such that you can perform an image promotion between staging and production.
oc login -u $(whoami) https://openshift.ocp-dev.drw
docker login -u $(oc whoami) -p $(oc whoami -t) registry.apps.ocp-dev.drw
make promote
