After you create configurations in Microservices Engine (MSE), you can query, edit, import, export, clone, and delete them from the MSE console. Configuration changes take effect immediately after you publish them, with no application restart required.
Prerequisites
Before you begin, ensure that you have:
An MSE Nacos instance
Access to the MSE console
Navigate to the configurations page
All operations in this document start from the Configurations page.
Log on to the MSE console and select a region in the top navigation bar.
On the Instances page, click the name of the instance.
In the left-side navigation pane, choose Configuration Management > Configurations.
Query configurations
Filter configurations by Namespace, Group, Data ID, Application, or Tags.
In the upper part of the Configurations page, specify one or more filter criteria.
Click Query.
The following table lists the operations you can perform on query results.
| Action | Steps |
|---|---|
| View configuration details | Click a Data ID value in the Data ID column. |
| Edit a configuration | Click Edit in the Actions column. |

View configuration details
On the Configurations page, find the target configuration and click its Data ID value.
On the details page, review the configuration across the following tabs:
Tab Description Configuration Content The current content of the configuration. Sample Code Code snippets for accessing the configuration. Versions The version history of the configuration. Listening Query Clients that are listening to the configuration.
Edit a configuration
Use Beta Release to validate changes on a subset of instances before a full rollout. This reduces the risk of configuration errors affecting all instances at once.
On the Configurations page, find the target configuration and click Edit in the Actions column.
In the Edit Configuration panel, modify the configuration. The Edit Configuration panel includes all settings available in the Add Configuration panel, plus the following features: Beta Release Turn on the Beta Release switch to publish the configuration to specific instances first. Enter the IP addresses of the instances on which to verify the configuration. For an on-premises machine, enter its public IP address. After you confirm that the configuration works correctly on these instances, publish it to all instances. Comparison of Configuration Content After you click Release, a comparison view shows the differences between the original configuration and your changes. Review the comparison to catch accidental errors before you confirm the release.
Click Release.
