You can delete ACK Serverless clusters in the Container Service for Kubernetes (ACK) console. The cluster deletion page displays the existing resources in the cluster that you want to delete. You can check the resources to be deleted and choose the resources that you want to retain. Read the information on the page and make sure that you understand the risks that may arise after the cluster is deleted
Before you delete an ACK cluster, you need to manually delete the workloads in the cluster, including Deployments, StatefulSets, Jobs, and CronJobs. Otherwise, you may fail to delete the cluster. For more information about Kubernetes workloads, see Workloads.
Log on to the ACK console. In the left-side navigation pane, click Clusters.
On the Clusters page, choose in the Actions column of the cluster that you want to delete.
In the Delete Cluster dialog box, select the resources that you want to release or retain, select I understand the above information and want to delete the specified cluster, and then click OK.
