## kubectl drain
|
|
|
|
Drain node in preparation for maintenance
|
|
|
|
### Synopsis
|
|
|
|
|
|
|
|
Drain node in preparation for maintenance.
|
|
|
|
The given node will be marked unschedulable to prevent new pods from arriving.
|
|
Then drain deletes all pods except mirror pods (which cannot be deleted through
|
|
the API server). If there are DaemonSet-managed pods, drain will not proceed
|
|
without --ignore-daemonsets, and regardless it will not delete any
|
|
DaemonSet-managed pods, because those pods would be immediately replaced by the
|
|
DaemonSet controller, which ignores unschedulable markings. If there are any
|
|
pods that are neither mirror pods nor managed--by ReplicationController,
|
|
ReplicaSet, DaemonSet or Job--, then drain will not delete any pods unless you
|
|
use --force.
|
|
|
|
When you are ready to put the node back into service, use kubectl uncordon, which
|
|
will make the node schedulable again.
|
|
|
|
|
|
|
|
|
|
```
|
|
kubectl drain NODE
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
|
|
# Drain node "foo", even if there are pods not managed by a ReplicationController, ReplicaSet, Job, or DaemonSet on it.
|
|
$ kubectl drain foo --force
|
|
|
|
# As above, but abort if there are pods not managed by a ReplicationController, ReplicaSet, Job, or DaemonSet, and use a grace period of 15 minutes.
|
|
$ kubectl drain foo --grace-period=900
|
|
|
|
```
|
|
|
|
### Options
|
|
|
|
```
|
|
--delete-local-data Continue even if there are pods using emptyDir (local data that will be deleted when the node is drained).
|
|
--force Continue even if there are pods not managed by a ReplicationController, ReplicaSet, Job, or DaemonSet.
|
|
--grace-period int Period of time in seconds given to each pod to terminate gracefully. If negative, the default value specified in the pod will be used. (default -1)
|
|
--ignore-daemonsets Ignore DaemonSet-managed pods.
|
|
```
|
|
|
