Delete an ApeCloud MySQL Cluster

Termination policy

NOTE

The termination policy determines how a cluster is deleted.

terminationPolicyDeleting Operation
DoNotTerminateDoNotTerminate blocks delete operation.
HaltHalt 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.
DeleteDelete extends the Halt policy by also removing PVCs, leading to a thorough cleanup while removing all persistent data.
WipeOutWipeOut 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 get cluster mycluster -n demo > NAME CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS AGE mycluster apecloud-mysql ac-mysql-8.0.30 Delete Running 27m
kbcli cluster list -n demo > NAME NAMESPACE CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS CREATED-TIME mycluster demo apecloud-mysql ac-mysql-8.0.30 Delete Running Sep 19,2024 16:01 UTC+0800

Step

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
