Draining a Kubernetes Node – Platform9

Problem

Load-average on the master node goes high causing Kubernetes related services to fail.
The node may become unstable in terms of Kubernetes workloads and customer may decide to evict the node.

Run the command to drain the node.
```
$ kubectl drain <node_name>
```
The above command may fail if the pods are using local storage or if daemon sets are running on the node. In that case, be aware that local storage associated with the pods will be deleted and then use the above command with switches --delete-local-data=false and ignore-daemonsets=false.
```
$ kubectl drain <node_name> --delete-local-data=false --ignore-daemonsets=false
```
