：UpdateStackGroup

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

The region ID of the stack group. You can call the DescribeRegions operation to query the latest list of Alibaba Cloud regions.

The name of the stack group. The name must be unique within a region.

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

The description of the stack group.

The description must be 1 to 256 characters in length.

The IDs of the accounts within which you want to use self-managed permissions to deploy stacks. You can specify a maximum of 20 account IDs.

The region IDs of stack instances. You can specify a maximum of 20 region IDs.

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 exceeds the upper limit, we recommend that you add parameters to the HTTP POST request body to prevent request failures caused by excessively long URLs.

The URL of the file that contains the template body. The URL must point to a template that is located on an HTTP or HTTPS web server or in an Alibaba Cloud Object Storage Service (OSS) bucket. The template body must be 1 to 524,288 bytes in length. Examples: oss://ros/template/demo and oss://ros/template/demo?RegionId=cn-hangzhou. If you do not specify the region ID of the OSS bucket, the value of the RegionId parameter is used.

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 make sure that the token is unique among different requests.

The token can be up to 64 characters in length and can contain letters, digits, hyphens (-), and underscores (_).

For more information, see Ensure idempotence.

The description of the operation to update the stack group.

The preferences of the operation to update the stack group.

The following parameters are available:

• {"FailureToleranceCount": N}

  The maximum number of accounts within which stack operation failures are allowed in each region. If the value is exceeded in a region, ROS stops the operation in the region. If ROS stops the operation in one region, the operation is not performed in other regions.

  Valid values of N: 0 to 20.

  If you do not specify a value for the FailureToleranceCount parameter, the default value 0 is used.

• {"FailureTolerancePercentage": N}

  The percentage of accounts within which stack operation failures are allowed in each region. If the value is exceeded in a region, ROS stops the operation in the region.

  Valid values of N: 0 to 100. If the number of accounts specified by the percentage is not a whole number, ROS rounds down the number.

  If you do not specify a value for the FailureTolerancePercentage parameter, the default value 0 is used.

• {"MaxConcurrentCount": N}

  The maximum number of accounts within which stacks can be deployed at a time in each region.

  Valid values of N: 1 to 20.

  If you do not specify a value for the MaxConcurrentCount parameter, the default value 1 is used.

• {"MaxConcurrentPercentage": N}

  The percentage of accounts within which stacks can be deployed at a time in each region.

  Valid values of N: 1 to 100. If the number of accounts specified by the percentage is not a whole number, ROS rounds down the number.

  If you do not specify a value for the MaxConcurrentPercentage parameter, the default value 1 is used.

• {"RegionConcurrencyType": N}

  Specifies whether stacks can be deployed in multiple regions in parallel. Valid values:

  • SEQUENTIAL: deploys stacks in the specified regions one by one in sequence. This way, stacks are deployed in only one region at a time. This is the default value.
  • PARALLEL: deploys stacks in all the specified regions in parallel.

Separate multiple parameters with commas (,).

The name of the RAM role to be assumed by the administrator account in ROS. This parameter is required if you want to grant self-managed permissions to the stack group. If you do not specify a value for this parameter, the default value AliyunROSStackGroupAdministrationRole is used. You can use the administrator role in ROS to assume the execution role AliyunROSStackGroupExecutionRole to perform operations on the stacks that correspond to stack instances in the stack group.

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

The name of the RAM role to be assumed by the administrator role AliyunROSStackGroupAdministrationRole. This parameter is required if you want to grant self-managed permissions to the stack group. If you do not specify a value for this parameter, the default value AliyunROSStackGroupExecutionRole is used. You can use this role in ROS to perform operations on the stacks that correspond to stack instances in the stack group.

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

The ID of the template. This parameter applies to shared and private templates.

The version of the template. If you do not specify a version, the latest version is used.

The permission model.

Valid values:

• SELF_MANAGED: the self-managed permission model. This is the default value. If you use the self-managed model for the stack group, you must create RAM roles for the administrator and execution accounts, and establish a trust relationship between the accounts to deploy stacks within the execution account.
• SERVICE_MANAGED: the service-managed permission model. If you use the service-managed model for the stack group, ROS creates service-linked roles for the administrator and execution accounts, and the administrator account uses its role to deploy stacks within the execution account.

The key of parameter N. If you do not specify the key and value of the parameter, ROS uses the default key and value in the template.

Maximum value of N: 200.

The value of parameter N.

Maximum value of N: 200.

The ID of the request.

The ID of the operation.
