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.

kubectl -n demo get cluster mycluster 
>
NAME        CLUSTER-DEFINITION   VERSION       TERMINATION-POLICY   STATUS    AGE
mycluster   mongodb              mongodb-5.0   Delete               Running   17m

Steps

Run the command below to delete the cluster.

kubectl delete -n demo cluster mycluster

If you want to delete a cluster and its all related resources, you can set 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
