Request parameters
Parameter | Type | Required | Example | Description |
---|---|---|---|---|
Action | String | Yes | ValidateTemplate |
The operation that you want to perform. Set the value to ValidateTemplate. |
TemplateURL | String | No | oss://ros/template/demo |
The URL for the file that contains the template body. The URL must point to a template located in an HTTP or HTTPS web server or an Alibaba Cloud OSS bucket. Examples: oss://ros/template/demo and oss://ros/template/demo?RegionId=cn-hangzhou. The template can be up to 524,288 bytes in length, and the URL can be up to 1,024 bytes in length. Note If the region of the OSS bucket is not specified, the RegionId parameter value is
used by default.
You must specify one of the TemplateBody and TemplateURL parameters, but you cannot specify both of them. |
RegionId | String | No | cn-hangzhou |
The region ID of the stack template. You can call the DescribeRegions operation to query the most recent region list. |
TemplateBody | String | No | {"ROSTemplateFormatVersion":"2015-09-01"} |
The structure that contains the template body. The template body must be 1 to 524,288 bytes in length. If the length of the template body is longer than required, we recommend that you add parameters to the HTTP POST request body to avoid request failures due to excessive length of URLs. You must specify one of the TemplateBody and TemplateURL parameters, but you cannot specify both of them. |
