UpdateStack - Resource Orchestration Service - Alibaba Cloud Documentation Center

The values in the Parameters section vary based on the value that you specify for the UsePreviousParameters parameter in the request. If you do not add parameters that are defined in the template to the Parameters section, take note of the following items:

UsePreviousParameters is set to false: If the template parameters have default values, the default values are used. Otherwise, you must specify values for the template parameters in the Parameters section.
UsePreviousParameters is set to true: If you set the template parameters to specific values when you create a stack, the values are used. If you leave the template parameters empty when you create a stack but the template parameters have default values, the default values are used.

In this example, the template body of a stack whose ID is 4a6c9851-3b0f-4f5f-b4ca-a14bf691**** in the China (Beijing) region is updated to {"ROSTemplateFormatVersion": "2015-09-01"}.

Debugging

Note You must specify only one of the following parameters: TemplateBody, TemplateURL, and TemplateId.
RamRoleName	String	No	test-role	The name of the RAM role. Resource Orchestration Service (ROS) assumes the RAM role to create the stack and uses the credentials of the role to call the APIs of Alibaba Cloud services. ROS assumes the RAM role to perform operations on the stack. If you have permissions to perform operations on the stack but do not have permissions to use the role, ROS still assumes the role. Make sure that the least privileges are granted to this role. If you do not specify this parameter, ROS assumes the existing role that is associated with the stack. If no roles are available, ROS uses the temporary credentials that are generated from the credentials of your account. The name can be up to 64 bytes in length.
ReplacementOption	String	No	Disabled	Specifies whether to enable the replacement update feature. If you cannot change resource properties, you can enable the replacement update feature to replace the resource properties. If the replacement update feature is enabled for a resource, the resource is deleted and a new resource with a different physical ID is created. Default value: Disabled. Valid values: Enabled: enables the replacement update feature. Disabled: disables the replacement update feature. Note Changes have higher priorities than replacement updates.
TemplateId	String	No	5ecd1e10-b0e9-4389-a565-e4c15efc****	The ID of the template. This parameter applies to shared and private templates. Note You must specify only one of the following parameters: TemplateBody, TemplateURL, and TemplateId.

Parameters.N.ParameterKey	String	Yes	Amount	The name of parameter N. If you do not specify a name and a value for a parameter, ROS uses the default name and value in the template. Maximum value of N: 200. Note The Parameters parameter in Parameters.N.ParameterValue is optional. If you want to specify Parameters, you must specify Parameters.N.ParameterKey and Parameters.N.ParameterValue.
Parameters.N.ParameterValue	String	Yes	12	The value of parameter N. Maximum value of N: 200. Note The Parameters parameter in Parameters.N.ParameterValue is optional. If you want to specify Parameters, you must specify Parameters.N.ParameterKey and Parameters.N.ParameterValue.
Tags.N.Key	String	Yes	usage	The key of tag N that you want to add to the stack. Valid values of N: 1 to 20. Note Tags in Tags.N.Key is optional. If you want to specify Tags, you must specify Tags.N.Key. The tag of a stack is propagated to each stack resource that supports the tag feature. For more information, see Propagate tags.
Tags.N.Value	String	No	test	The value of tag N that you want to add to the stack. Valid values of N: 1 to 20. Note The tag of a stack is propagated to each stack resource that supports the tag feature. For more information, see Propagate tags.
Parallelism	Long	No	1	The maximum number of concurrent operations that can be performed on resources. This parameter takes effect only for Terraform stacks. By default, this parameter is empty. You can set this parameter to an integer greater than or equal to 0. Note If you set this parameter to an integer greater than 0, the integer is used as the maximum number of operations. If you set this parameter to 0, the default value in Terraform is used as the maximum number of operations. In most cases, the default value in Terraform is 10. If you leave this parameter empty, the value that you specify for this parameter in the previous operation is used. If you left this parameter empty in the previous operation, the default value in Terraform is used. In most cases, the default value in Terraform is 10. If you set this parameter to a specific value, ROS associates the value with the stack. The value can affect subsequent operations on the stack.
