Delete a Redis Cluster

Termination policy

note

The termination policy determines how a cluster is deleted.

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

kbcli cluster list redis-cluster
>
NAME            NAMESPACE   CLUSTER-DEFINITION  VERSION         TERMINATION-POLICY  STATUS       CREATED-TIME

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 redis -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge"

kubectl delete -n demo cluster redis
