- Drain a node and delete pods using emptyDir volumes (local data will be lost):
kubectl drain {{node_name}} --ignore-daemonsets --delete-emptydir-data

kubectl drain {{node_name}} --force
- Drain a node with a custom grace period for pod termination:
kubectl drain {{node_name}} --grace-period {{seconds}}
- Drain a node, evicting only pods that match a label selector:
kubectl drain {{node_name}} --pod-selector {{label_key}}={{label_value}}
- Drain a node with a timeout:

- Preview the drain operation without actually evicting pods (dry run):
kubectl drain {{node_name}} --dry-run={{none|server|client}}
