Dedicate nodes to a workload using labels and nodeSelectorTask Information : Label two nodes with...

Label the chosen worker nodes

oc label node worker-1 workload=payments

oc label node worker-2 workload=payments

Node labels are key/value metadata used by the scheduler.

Add a nodeSelector to the deployment

oc -n payments patch deploy api --type=merge -p '{

"spec":{"template":{"spec":{"nodeSelector":{"workload":"payments"}}}}

}'

Forces pods to schedule only to nodes that match the label.

Verify placement

oc -n payments get pods -o wide

Confirms pods are running on the intended nodes.
