    kubectl get nodes --show-lables
  

Node Maintenance (Cordon/Drain)

• Cordon a Node
  Prevent new pods from being scheduled on the node.

  kubectl cordon <node-name>
  

• Uncordon a Node
  Mark the node as schedulable again.

  kubectl uncordon <node-name>
  

• Drain a Node
  Evict all pods from the node (excluding those managed by DaemonSets).

  kubectl drain <node-name> --ignore-daemonsets --delete-local-data
  

  Warning: Draining a node will evict running pods. Ensure that you plan this action to avoid service disruption.
