 Marking a node as unschedulable prevents the scheduler from placing new Pods onto that node while not affecting existing Pods on the node. This is useful as a preparatory step before a node reboot or other maintenance.
 
-Log in to the console as `admin` and go to the **Cluster Management** page. To mark a node unschedulable, choose **Cluster Nodes** under **Nodes** from the left menu, find a node you want to remove from the cluster, and click **Cordon**. Alternatively, you can run the command `kubectl cordon $NODENAME` directly. See [Kubernetes Nodes](https://kubernetes.io/docs/concepts/architecture/nodes/) for more details.

 将节点标记为不可调度可防止调度程序将新的 Pod 放置到该节点上，同时不会影响该节点上的现有 Pod。作为节点重启或者其他维护之前的准备步骤，这十分有用。
 
-以 `admin` 身份登录控制台，访问**集群管理**页面。若要将节点标记为不可调度，从左侧菜单中选择**节点管理**下的**集群节点**，找到想要从集群中删除的节点，点击**停止调度**按钮。或者，直接执行命令 `kubectl cordon $NODENAME`。有关更多详细信息，请参见 [Kubernetes 节点](https://kubernetes.io/docs/concepts/architecture/nodes/)。
