UpdateStackGroup

The operation that you want to perform. Set the value to UpdateStackGroup.

The name of parameter N. If the name and value of the parameter are not specified, the name and value specified in the template are used.

Maximum value of N: 200.

The value of parameter N.

Maximum value of N: 200.

The region ID of the stack. You can call the DescribeRegions operation to query the most recent region list.

The name of the stack group. The name must be unique in a region. The name can be up to 255 characters in length and can contain digits, letters, hyphens (-), and underscores (_). It must start with a digit or letter.

The description of the stack group.

The description must be 1 to 256 characters in length.

The list of target account IDs, in JSON format. A maximum of 20 IDs are supported.

The list of target regions, in JSON format. A maximum of 20 regions are supported.

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 either the TemplateBody parameter or the TemplateURL parameter. But you cannot specify both of them.

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. If the region of the OSS bucket is not specified, the RegionId parameter value is used by default. The template can be up to 524,288 bytes in length.

You must specify either the TemplateBody parameter or the TemplateURL parameter. But you cannot specify both of them.

The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests. The token can contain only letters, digits, hyphens (-), and underscores (_) and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.

The description of the operation. The description describes the purpose or action of the operation.

The operation settings, in JSON format. The following fields are supported:

• FailureToleranceCount

The maximum number of stack operation failures that can occur. In a stack group operation, if the total number of failures does not exceed the FailureToleranceCount value, the operation succeeds. Otherwise, the operation fails.

If the FailureToleranceCount parameter is not specified, the default value is 0. You can specify either the FailureToleranceCount parameter or the FailureTolerancePercentage parameter. But you cannot specify both of them.

Valid values: 0 to 20.

• FailureTolerancePercentage

The percentage of stack operation failures that can occur. In a stack group operation, if the percentage of failures does not exceed the FailureTolerancePercentage value, the operation succeeds. Otherwise, the operation fails.

You can specify either the FailureToleranceCount parameter or the FailureTolerancePercentage parameter. But you cannot specify both of them.

Valid values: 0 to 100.

• MaxConcurrentCount

The maximum number of target accounts in which a stack group operation can be performed at one time.

You can specify either the MaxConcurrentCount parameter or the MaxConcurrentPercentage parameter. But you cannot specify both of them.

Valid values: 1 to 20.

• MaxConcurrentPercentage

The maximum percentage of target accounts in which a stack group operation can be performed at one time.

You can specify either the FailureToleranceCount parameter or the FailureTolerancePercentage parameter. But you cannot specify both of them.

Valid values: 1 to 100.

The name of the RAM administrator role assumed by ROS. ROS assumes this role to play the execution role to operate on the stack corresponding to the stack instance in the stack group.

The RAM role is specified only when the custom administrator role is used to control the users or groups that can manage specified stack groups under the same administrator account. Default value: AliyunROSStackGroupAdministrationRole.

The name must be 1 to 64 characters in length and can contain letters, digits, and hyphens (-).

Default value: AliyunROSStackGroupExecutionRole.
