This topic describes the release notes for resource-controller.

Introduction

ack-slo-manager supports all the features of resource-controller and provides optimizations. resource-controller is no longer available since October 14, 2022. For more information about how to use ack-slo-manager, see ack-slo-manager. If your cluster uses resource-controller, we recommend that you upgrade from resource-controller to ack-slo-manager. For more information about how to upgrade from resource-controller to ack-slo-manager, see Migrate components.

Uninstall resource-controller

In 1.2.3-ea712cc6-aliyun and later versions, the Cgroup CustomResourceDefinition (CRD) is retained after you uninstall resource-controller. This makes it convenient for you to switch from resource-controller to ack-slo-manager. For more information about the Cgroup CRD, see Dynamically modify the resource parameters of a pod. If the related Cgroups are no longer needed after you uninstall resource-controller, we recommend that you delete the Cgroups in your cluster to prevent the Cgroups from affecting ack-slo-manager.

To uninstall resource-controller and delete the related Cgroups, perform the following steps:

  1. Uninstall resource-controller. For more information, see Manage system components.
  2. Delete the related Cgroups.
    1. Log on to the ACK console and click Clusters in the left-side navigation pane.
    2. On the Clusters page, click the name of a cluster and choose Workloads > Custom Resources in the left-side navigation pane.
    3. On the Custom Resources page, click the CRDs tab. Then, click Cgroups.
    4. On the Resource Objects tab, select All Namespaces from the Namespace drop-down list.
    5. In the list that appears, select all Cgroups and click Delete. In the Confirm message, click OK.
