Stopping a Node¶
Scenario¶
After a node in the cluster is stopped, services on the node are also stopped. Before stopping a node, ensure that discontinuity of the services on the node will not result in adverse impacts.
Constraints¶
Deleting a node will lead to pod migration, which may affect services. Therefore, delete nodes during off-peak hours.
Unexpected risks may occur during the operation. Back up related data in advance.
While the node is being deleted, the backend will set the node to the unschedulable state.
Only worker nodes can be stopped.
Procedure¶
Log in to the CCE console and click the cluster name to access the cluster console.
In the navigation pane, choose Nodes. On the displayed page, click the Nodes tab.
Locate the target node and click its name.
In the upper right corner of the ECS details page, click Stop. In the displayed dialog box, click Yes.
