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

  • After a CCE cluster is deleted, the ECS nodes in the cluster are also deleted.

Notes

  • 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. In the navigation pane, choose Resource Management > Nodes. In the same row as the node you will delete, choose More > Delete.
  2. In the Delete Node dialog box, enter DELETE and click Yes.

    • 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.
