1. API Description

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

This API is used to create launch configurations and scaling groups based on an instance.

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

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: CreateAutoScalingGroupFromInstance.
Version	Yes	String	Common Params. The value used for this API: 2018-04-19.
Region	Yes	String	Common Params. For more information, please see the list of regions supported by the product.
AutoScalingGroupName	Yes	String	The scaling group name. It must be unique under your account. The name can only contain letters, numbers, underscore, hyphen "-" and periods. It cannot exceed 55 bytes.
InstanceId	Yes	String	Instance ID. you can get the instance ID by logging in to the console or making an api call to DescribeInstances and retrieving the `InstanceId` from the returned information.
MinSize	Yes	Integer	Minimum number of instances. value range: [0,2000]. to meet MaxSize >= DesiredCapacity >= MinSize at the same time.
MaxSize	Yes	Integer	Maximum instance count. value range [0,2000]. to meet MaxSize >= DesiredCapacity >= MinSize.
DesiredCapacity	No	Integer	Expected number of instances, value ranges from 0 to 2000, default value equals current MinSize, to meet MaxSize >= DesiredCapacity >= MinSize.
InheritInstanceTag	No	Boolean	Whether to inherit the instance tag. Default value: False

3. Output Parameters

Parameter Name	Type	Description
AutoScalingGroupId	String	The scaling group ID.
RequestId	String	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

4. Example
