Cluster Management
Configuration
High Availability
The termination policy determines how a cluster is deleted.
| terminationPolicy | Deleting Operation |
|---|---|
DoNotTerminate | DoNotTerminate blocks delete operation. |
Halt | Halt deletes Cluster resources like Pods and Services but retains Persistent Volume Claims (PVCs), allowing for data preservation while stopping other operations. Halt policy is deprecated in v0.9.1 and will have same meaning as DoNotTerminate. |
Delete | Delete extends the Halt policy by also removing PVCs, leading to a thorough cleanup while removing all persistent data. |
WipeOut | WipeOut deletes all Cluster resources, including volume snapshots and backups in external storage. This results in complete data removal and should be used cautiously, especially in non-production environments, to avoid irreversible data loss. |
To check the termination policy, execute the following command.
kubectl -n demo get cluster mycluster
>
NAME CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS AGE
mycluster redis Delete Running 10m
kbcli cluster list mycluster -n demo
NAME NAMESPACE CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS CREATED-TIME
mycluster demo redis Delete Running Apr 10,2023 20:27 UTC+0800
Run the command below to delete a specified cluster.
kubectl delete cluster mycluster -n demo
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
