    Container Service for Kubernetes:Enable Fleet management

    Last Updated:Jun 17, 2026

    Schedule and distribute workloads, applications, and configurations across multiple clusters by enabling ACK One Fleet management.

    Prerequisites

    Verify the following:

    • An Alibaba Cloud account. RAM users are not supported.

    Enable Fleet management

    1. Log on to the ACK One console.

    2. On the Create Fleet page, configure the Fleet instance.

      Parameter Description
      Region The region of the clusters to manage.
      VPC The VPC for the Fleet instance.
      vSwitch The vSwitch for the Fleet instance.
      Resource Group The resource group of the Fleet instance.
      Labels Key-value pairs attached to the Fleet instance. Keys: required, unique, max 64 characters. Values: optional, max 128 characters. Cannot start with aliyun, acs:, https://, or http://. Not case-sensitive. Duplicate keys overwrite existing labels. Exceeding 20 labels invalidates all labels on the resource.
      SLB instance for API server The SLB instance for the API server. Defaults to Standard I (slb.s2.small) and cannot be changed.
      Create and associate EIP Specifies whether to expose the API server to the Internet. Disabled by default. If enabled, an EIP is associated with the internal-facing SLB instance, allowing Internet access to the API server. The EIP cannot be disassociated after association because clusters may already connect over the Internet.
      Enable collection of operation logs and auditing logs Whether to collect operation and audit logs. Enabled by default.

    3. Click Enable Fleet Management.

    4. Wait until the Fleet instance status changes to Running on the Fleet Information page.

    Manage Fleet instances

    Enabling Fleet management creates a default Fleet instance.

    2. In the Create Fleet panel, set the following parameters:

      Parameter Description
      Fleet Name The Fleet instance name.
      Region The region of the clusters to manage.
      VPC The VPC for the Fleet instance.
      vSwitch The vSwitch for the Fleet instance.
      Resource Group The resource group of the Fleet instance.
      Labels Key-value pairs attached to the Fleet instance. Keys: required, unique, max 64 characters. Values: optional, max 128 characters. Cannot start with aliyun, acs:, https://, or http://. Not case-sensitive. Duplicate keys overwrite existing labels. Exceeding 20 labels invalidates all labels on the resource.

    2. List the clusters associated with the Fleet instance:

      kubectl amc get managedcluster

      Expected output:

      Name                                Alias              HubAccepted
