Alibaba Cloud Service Mesh:Add a cluster to an ASM instance

Last Updated:Jan 25, 2024

After you add a Container Service for Kubernetes (ACK) cluster to a Service Mesh (ASM) instance, you can use the traffic management, troubleshooting, centralized monitoring, and log management features provided by ASM to enhance system reliability and security, better manage and monitor service interactions, and improve service observability.

Prerequisites

Procedure

  1. Log on to the ASM console. In the left-side navigation pane, choose Service Mesh > Mesh Management.

  2. On the Mesh Management page, click the name of the ASM instance. In the left-side navigation pane, choose Cluster & Workload Management > Kubernetes Clusters. On the page that appears, click Add.

  3. In the Add Kubernetes Cluster page, select the cluster that you want to add and click OK.

    • If your application runs in a single cluster or multiple clusters in a VPC, we recommend that you click Filter out Kubernetes clusters that are in the same VPC as the ASM instance to filter clusters. Then, select the ACK cluster that you want to add from the cluster list.

    • 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.

  4. In the Note message, click OK.

    After you add a cluster to the ASM instance, you can find that the Status of the ASM instance changes to Updating on the ASM Instance > Base Information page. Wait a few seconds and click Refresh in the upper-right corner. The Status of the ASM instance becomes Running. The waiting duration varies with the number of clusters that you added. On the Kubernetes Clusters page, you can view the information about the added cluster.

Note

If you no longer need a cluster in the ASM instance, you can remove the cluster from the ASM instance. On the Kubernetes Clusters page, select the cluster that you want to remove and click Remove. In the Submit dialog box, click OK.

After you remove a cluster, Service Mesh is unavailable to this cluster. Exercise caution when you remove a cluster.
