Deleting a Cluster

Deleting a cluster will delete the workloads and Services in the cluster, and the deleted data cannot be recovered. Before performing this operation, ensure that related data has been backed up or migrated.
If you choose to delete a cluster with the nodes in it, the system disks and data disks attached to the nodes will also be deleted. Back up data before the deletion.
If you delete a cluster that is not running (for example, unavailable), associated resources, such as storage and networking resources, will remain.

A hibernated cluster cannot be deleted. Wake up the cluster and try again.

Log in to the CCE console. In the navigation pane, choose Clusters.
Locate the cluster to be deleted, click ... to view more operations on the cluster, and choose Delete.
In the displayed Delete Cluster dialog box, select the resources to be released.
- When you delete nodes from a cluster, the following options are available:
  - Retain: The node as well as the data on the system disk and data disks will be retained.
  - Delete: The node will be deleted with the cluster.
  - Reset: The node will be retained and reset. The data on the system disk and data disks will not be retained.
- Delete cloud storage resources associated with workloads in the cluster.
  When deleting underlying cloud storage resources bound to storage volumes in a cluster, pay attention to following constraints:
  - The underlying storage resources are deleted according to the reclamation policy you defined for the storage volumes. For example, if the reclamation policy of storage volumes is Retain, the underlying storage resources will be retained after the cluster is deleted.
  - If there are more than 1000 files in the OBS bucket, manually clear the files and then delete the cluster.
- Delete network resources such as load balancers in a cluster. (Only automatically created load balancers will be deleted).
Enter DELETE and click Yes to start deleting the cluster.

The delete operation takes 1 to 3 minutes to complete.
