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.
• If ECS nodes are billed on a yearly/monthly basis, they cannot be directly deleted. You can choose Billing Center > My Orders to unsubscribe from the nodes.
  

  For clusters of v1.17.11 or later, after a VM is unsubscribed from or deleted on the ECS console, the corresponding node in the CCE cluster is automatically 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.

   • 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.
   • ECSs are released during node deletion only if they are billed in pay-per-use mode.
