Cordon a Node
Marking a node as unschedulable prevents the scheduler from placing new pods onto that Node, but does not affect existing Pods on the Node. This is useful as a preparatory step before a node reboot or other maintenance.
To mark a Node unschedulable, you can choose Nodes → Cluster Nodes from the menu, then find a node you want to remove from the cluster and click the Cordon button. It takes the same effect with the command kubectl cordon $NODENAME, you can see the Kubernetes Nodes for more details.
{{< notice note >}} Note: Pods that are part of a DaemonSet tolerate being run on an unschedulable Node. DaemonSets typically provide node-local services that should run on the Node even if it is being drained of workload applications. {{</ notice >}}
Delete a Node
You can delete the node by the following command:
./kk delete node <nodeName> -f config-sample.yaml
