Goal

Trace targeted scheduling with node labels, node affinity and tolerations.

What Is Done

A Pod requires a node with workshop-role=isolated and also tolerates the taint workshop=isolated:NoSchedule.

Typical Commands

kubectl label node <node-name> workshop-role=isolated
kubectl taint node <node-name> workshop=isolated:NoSchedule
kubectl apply -f manifests/
kubectl get pods -n scheduling-lab -o wide

Validate Success

• The Pod is scheduled on the labeled node.
• Without the matching label, the Pod stays Pending.
• The toleration matches the taint.

Common Mistakes

• Label and affinity key do not match.
• The taint is not removed after the lab.
• requiredDuringSchedulingIgnoredDuringExecution is confused with preferred affinity.
