Updates for the (Discontinued) resource-controller component-Container Service for Kubernetes(ACK)-阿里云帮助中心

Component overview

ack-slo-manager now supports all the features of resource-controller and includes optimizations over the original component. The resource-controller component was decommissioned on October 14, 2022. For instructions on how to use these features, see ack-koordinator (ack-slo-manager). If you are using resource-controller, refer to Related Content to complete the migration.

Uninstall resource-controller

To facilitate the migration to ack-koordinator (ack-slo-manager), starting from version v1.2.3-ea712cc6-aliyun, uninstalling resource-controller no longer automatically deletes the Cgroup CustomResourceDefinition (CRD). For more information about the Cgroup CRD, see Dynamically modify the resource parameters of a Pod. If you no longer need the Cgroup CRD features after the uninstallation, follow the steps below to clean up the remaining Cgroup Custom Resources (CRs) in your cluster. This cleanup prevents potential conflicts with ack-slo-manager.

To uninstall resource-controller and delete the Cgroup CRs:

Uninstall the resource-controller component. For detailed instructions, see Manage components.
Delete the Cgroup CRs.
1. Log on to the ACK console. In the left navigation pane, click Clusters.
2. On the Clusters page, click the name of your cluster. In the left navigation pane, click Workloads > Custom Resources.
3. On the Custom Resources page, click the CRDs tab, and then click Cgroups.
4. On the Resource Objects tab, set Namespace to All Namespaces.
5. Select all Cgroup objects, click Are you sure you want to delete, and then in the Confirm dialog box, click OK.
