Very nicely explained.
Hi Sir Why not you used simple command example: the first deploy app then set resources - oc set resources deploy hello-limit --request cpu=1200m,memory=20Mi sorry sir I want to share to shorten the time during the exam not to teach

Yes here are always multiple short ways .. in OpenShift also one can do same thing via web console/commands/yaml .. I always try to give background & explanation . for this example also I used yaml to show that resource limit/requests will be configured in either deployment or deployment-config
