The termination policy determines how a cluster is deleted.
| terminationPolicy | Deleting Operation |
|---|---|
DoNotTerminate | DoNotTerminate prevents deletion of the Cluster. This policy ensures that all resources remain intact. |
Delete | Delete deletes Cluster resources like Pods, Services, and Persistent Volume Claims (PVCs), leading to a thorough cleanup while removing all persistent data. |
WipeOut | WipeOut is an aggressive policy that deletes all Cluster resources, including volume snapshots and backups in external storage. This results in complete data removal and should be used cautiously, primarily in non-production environments to avoid irreversible data loss. |
To check the termination policy, execute the following command.
kubectl get cluster mycluster -n demo
>
NAME CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS AGE
mycluster starrocks starrocks-3.1.1 Delete Running 34m
kbcli cluster list mycluster -n demo
>
NAME NAMESPACE CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS CREATED-TIME
mycluster demo Delete Running Sep 30,2024 13:03 UTC+0800
Run the command below to delete a specified cluster.
If you want to delete a cluster and its all related resources, you can modify the termination policy to WipeOut, then delete the cluster.
kubectl patch -n demo cluster mycluster -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge"
kubectl delete -n demo cluster mycluster
kbcli cluster delete mycluster -n demo
