Managing Historical Nacos Engine Versions

CSE Nacos allows you to view details about historical versions and roll back historical versions.

Viewing Historical Versions

You can view the configuration changes of historical versions to trace and audit the changes. If a problem occurs after the configuration is modified, for example, a service error is reported or the performance deteriorates, you can view the historical versions, compare the current configuration with the normal configuration, and quickly locate the configuration item and modification operation. In addition, Nacos supports one-click rollback to a stable version, which can quickly restore configurations and reduce the impact of faults on services.

  1. Click the target Nacos instance.
  2. In the left navigation pane, choose Configuration Management > Configurations.
  3. Go to the Historical Versions page in either of the following methods. Click the data ID of a historical version in a time segment to view the historical version information of the configuration item. Historical versions can be retained for a maximum of 30 days.

    • In the Operation column of the target data ID, choose More > Historical Versions.
    • Click the target data ID. On the Configuration Details page displayed, click the Historical Versions tab.
