- Drain a node:
|
||
|
|
|
||
|
|
`kubectl drain {{node_name}}`
|
||
|
|
|
||
|
|
- Drain a node, ignoring DaemonSet-managed pods:
|
||
|
|
|
||
|
|
`kubectl drain {{node_name}} --ignore-daemonsets`
|
||
|
|
|
||
|
|
- Drain a node and delete pods using emptyDir volumes (local data will be lost):
|
||
|
|
|
||
|
|
`kubectl drain {{node_name}} --ignore-daemonsets --delete-emptydir-data`
|
||
|
|
|
||
|
|
- Drain a node, forcing eviction of pods not managed by a controller:
|
||
|
|
|
||
|
|
`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:
|
||
|
|
|
||
|
|
`kubectl drain {{node_name}} --timeout {{duration}}`
|
||
|
|
|
||
|
|
- Preview the drain operation without actually evicting pods (dry run):
|
||
|
|
|
||
|
|
`kubectl drain {{node_name}} --dry-run={{none|server|client}}`
