Applications that are deployed in an Alibaba Cloud Service Mesh (ASM) instance run in clusters. To use an ASM instance to manage applications, you must add a Container Service for Kubernetes (ACK) cluster to the ASM instance.

Prerequisites

Procedure

  1. Log on to the ASM console.
  2. In the left-side navigation pane, choose Service Mesh > Mesh Management.
  3. On the Mesh Management page, find the ASM instance that you want to configure. Click the name of the ASM instance or click Manage in the Actions column.
  4. On the details page of the ASM instance, choose Cluster & Workload Management > Kubernetes Clusters in the left-side navigation pane. On the Kubernetes Clusters page, click Add.
  5. In the Add Cluster panel, select the cluster to be added to the ASM instance and click OK.
    Note
    • If your application runs in a single cluster or multiple clusters in a VPC, we recommend that you select Clusters in the Same VPC as the ASM Instance to filter clusters.
    • Make sure that the proxy container of the cluster to be added to the ASM instance can access Istio Pilot of the ASM instance. If Istio Pilot of the ASM instance does not allow Internet access, make sure that it can be accessed by the proxy container in the VPC.
  6. In the Note message, click OK.

Result

After you add a cluster to the ASM instance, the status of the ASM instance changes to Updating. Wait a few seconds and click the Refresh icon in the upper-right corner. If the cluster is added to the ASM instance, the status of the ASM instance becomes Running. You can add multiple clusters to the ASM instance at a time. The waiting duration may vary with the number of clusters that you add. On the Kubernetes Clusters page, you can view the information about the added cluster.
