Microservices Engine:Manage instances

Last Updated:Mar 11, 2026

Microservices Engine (MSE) provides managed Nacos and ZooKeeper instances for service registry and configuration management. After you create an instance, you can view its status and node health, rename it, restart individual nodes or all nodes, and release it when no longer needed.

Prerequisites

Before you begin, make sure that you have:

Open the instance details page

The view, rename, and restart operations are performed on the Basic Information page. To open this page:

  1. Log on to the MSE console.

  2. In the top navigation bar, select a region.

  3. In the left-side navigation pane, choose Microservices Registry > Instances.

  4. On the Instances page, click the name of the target instance.

View instance details

On the Basic Information page, you can view the basic information and node status of the instance.

Rename an instance

MSE auto-generates an instance name at creation time. Assign a meaningful name to make instances easier to identify:

  1. On the Basic Information page, click the MSE修改图标 icon next to Instance name.

  2. Enter a new name and click OK.

Restart an instance

Restart an instance after you modify its parameters or to resolve operational issues. You can restart all nodes at once or restart a single node.

Restart all nodes

  1. In the upper part of the Basic Information page, click Restart Instance.

  2. In the confirmation dialog box, click OK.

Note

A rolling restart is performed across all nodes. Each node takes approximately 1 to 2 minutes to restart. To minimize service disruption, perform this operation during off-peak hours.

Restart a single node

  1. On the Basic Information page, scroll to the Instance node section.

  2. Find the target node and click Restart in the Actions column.

  3. In the confirmation dialog box, click OK.

Release an instance

Releasing an instance permanently deletes the instance and all its data.

Important

Only pay-as-you-go instances can be manually released. After release, the instance and all associated data are permanently deleted.

Unlike the other operations above, you release an instance from the Instances list page:

  1. Log on to the MSE console and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, find the target instance.

  4. In the Actions column, choose More > Release Instance.

  5. In the dialog box, enter the instance name to confirm, and then click OK.
