Tag the Node node as needed

# oc label node node1.example.com node-role.kubernetes.io/compute=true# oc label node node2.example.com node-role.kubernetes.io/compute=true

Check the Pod status again

# oc get podsNAME READY STATUS RESTARTS AGEhello-openshift-1-deploy 0/1 ContainerCreating 0 18m

Check again after the meeting

# oc get podsNAME READY STATUS RESTARTS AGEhello-openshift-1-5hqc2 1 5hqc2 1 Running 0 22m

The problem is solved perfectly!
