## 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 any pods that are neither mirror pods nor
managed by a ReplicationController or DaemonSet, 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 or DaemonSet on it.
$ kubectl drain foo --force

# As above, but abort if there are pods not managed by a ReplicationController or DaemonSet, and use a grace period of 15 minutes.
$ kubectl drain foo --grace-period=900

```

### Options

```
      --force[=false]: Continue even if there are pods not managed by a ReplicationController or DaemonSet.
      --grace-period=-1: Period of time in seconds given to each pod to terminate gracefully. If negative, the default value specified in the pod will be used.
```
