1. API Description

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

This API is used to add existing instances to the compute environment.
Considerations:

For instances added to the compute environment, their UserData will be reset and the operating systems will be reinstalled.

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