This keeps new pods from landing on the node while you are trying to get them off.
1. Get the pods off the machine, via any of the following strategies:
1. wait for finite-duration pods to complete
1. for pods with a replication controller, delete the pod with `kubectl delete pods $PODNAME`
1. for pods which are not replicated, bring up a new copy of the pod, and redirect clients to it.
1. delete pods with `kubectl delete pods $PODNAME`
1. for pods with a replication controller, the pod will eventually be replaced by a new pod which will be scheduled to a new node. additionally, if the pod is part of a service, then clients will automatically be redirected to the new pod.
1. for pods with no replication controller, you need to bring up a new copy of the pod, and assuming it is not part of a service, redirect clients to it.
1. Work on the node
1. Make the node schedulable again:
`kubectl update nodes $NODENAME --patch='{"apiVersion": "v1beta1", "unschedulable": false}'`.
Or, if you deleted the VM instance and created a new one, and are using `--sync_nodes=true` on the apiserver
(the default), then a new schedulable node resource will be created automatically when you create a new
VM instance. See [Node](node.md).
If you deleted the node's VM instance and created a new one, then a new schedulable node resource will
be created automatically when you create a new VM instance (if you're using a cloud provider that supports
node discovery; currently this is only GCE, not including CoreOS on GCE using kube-register). See [Node](node.md).
