RollbackInstanceRefresh

Last updated: 2024-03-20 11:37:58

1. API Description

Domain name for API request: as.tencentcloudapi.com.

This API is used to generate a new instance refresh activity, which also supports batched refreshing and operations such as pausing, resuming, and canceling. The interface returns the RefreshActivityId for the rollback activity.

  • Instances pending refresh in the original activity are updated to a canceled status. Nonexistent instances are disregarded, while instances in all other statuses proceed to enter the rollback process.
  • Instances that were being refreshed in the original activity will not be immediately terminated; instead, the rollback activity will be executed after their refresh has been completed.
  • Rollback is supported for activities that are in a paused status or those with the most recent successful refresh; it is not supported for activities in other statuses.
  • When the original refresh activity involves reinstalling instances, for the ImageId parameter, it will automatically restore to the image ID before the rollback; for parameters such as UserData, EnhancedService, LoginSettings, and HostName, they will still be retrieved from the launch configuration, requiring users to manually modify the launch configuration before initiating the rollback.

A maximum of 20 requests can be initiated per second for this API.
