Delete a PostgreSQL Cluster

Termination policy​

note

The termination policy determines how a cluster is deleted.

terminationPolicyDeleting Operation
DoNotTerminateDoNotTerminate blocks delete operation.
HaltHalt deletes workload resources such as statefulset, deployment workloads but keep PVCs.
DeleteDelete deletes workload resources and PVCs but keep backups.
WipeOutWipeOut deletes workload resources, PVCs and all relevant resources included backups.

To check the termination policy, execute the following command.

kubectl -n demo get cluster mycluster
>
NAME        CLUSTER-DEFINITION   VERSION             TERMINATION-POLICY   STATUS    AGE
mycluster   postgresql           postgresql-14.8.0   Delete               Running   29m

Step​

Run the command below to delete the 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, and then delete the cluster.

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

kubectl delete -n demo cluster mycluster
