Deleting a Node

Scenario

When a node in a CCE cluster is deleted, services running on the node will also be deleted. Exercise caution when performing this operation.

Constraints

• VM nodes that are being used by CCE do not support deletion on the ECS page.

Precautions

• Deleting a node will lead to pod migration, which may affect services. Perform this operation 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 deleted.
• Nodes in a yearly/monthly node pool will be automatically migrated to the default node pool before they are unsubscribed from. Exercise caution when performing this operation.

Procedure

1. Log in to the CCE console and click the cluster name to access the cluster console.
2. In the navigation pane, choose Nodes. On the displayed page, click the Nodes tab.
3. Locate the target node and choose More > Delete in the Operation column.
4. In the Delete Node dialog box, enter DELETE and click Yes.
   

   • After the node is deleted, workload pods on the node are automatically migrated to other available nodes.
   • If the disks and EIPs bound to the node are important resources, unbind them first. Otherwise, they will be deleted with the node.
