Delete a MongoDB cluster
Termination policy
note
The termination policy determines how a cluster is deleted. Set the policy when creating a cluster.
| terminationPolicy | Deleting Operation |
|---|---|
DoNotTerminate | DoNotTerminate blocks delete operation. |
Halt | Halt deletes workload resources such as statefulset, deployment workloads but keep PVCs. |
Delete | Delete deletes workload resources and PVCs but keep backups. |
WipeOut | WipeOut deletes workload resources, PVCs and all relevant resources included backups. |
To check the termination policy, execute the following command.
- kbcli
- kubectl
kbcli cluster list mongodb-cluster
kubectl -n demo get cluster mongodb-cluster
>
NAME CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS AGE

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 mongodb-cluster -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge"
kubectl delete -n demo cluster mongodb-cluster
