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.

Notes and 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.
  • During the operation, the backend will set the node to the unschedulable state.
  • Only worker nodes can be deleted.

Procedure

  1. Log in to the CCE console and click the cluster name to access the cluster.

  2. In the navigation pane, choose Nodes. In the same row as the node you will delete, choose More > Delete.

  3. In the Delete Node dialog box, click Yes.

    Note

    • After the node is deleted, pods on it 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.
