Updates a stack.

The values in the Parameters section are related to the UsePreviousParameters value in the request. If you do not specify the parameters that are defined in the template as the parameters in the Parameters section, take note of the following items:

  • The UsePreviousParameters value is false: If a parameter in the template has a default value, the default value is used. If the parameter in the template does not have a default value, you must set a value for the parameter in the Parameters section.
  • The UsePreviousParameters value is true: If you set a parameter in the template to a specific value when you create a stack, the value is used. If you do not set a parameter in the template to a specific value, but the parameter has a default value in the template, the default value is used.

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

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

DisableRollback Boolean No false

Specifies whether to roll back the update operation on the stack when the stack fails to be updated.

Valid values:

  • true: rolls back the update operation.
  • false: does not roll back the update operation.

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 credential of the role to call the APIs of Alibaba Cloud services.

ROS assumes the role to perform operations on the stack. If you are authorized to perform operations on the stack but do not have permissions to use the role, ROS uses the role and you must make sure that least privileges are granted to this role.

If you do not specify this parameter, ROS uses the existing role that is associated with the stack. If no roles are available for ROS to assume, ROS uses the temporary credential that is 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 resource properties cannot be modified for an update, you can enable the replacement update feature to replace the resource properties.

Default value: Disabled. Valid values:

  • Enabled: enables the replacement update feature.
  • Disabled: disables the replacement update feature.
Note Operations that you perform to modify the resource properties for an update take precedence over operations you perform to replace the resource properties for an update.

This parameter is empty by default. 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 of Terraform is used as the maximum number of resources. In most cases, the default value of Terraform is 10.
  • If you do not set this parameter, the value that you set for this parameter in the last operation is used. If you did not set this parameter in the last operation, the default value of Terraform is used. In most cases, the default value of Terraform is 10.
  • If you set this parameter, ROS associates the value with the stack and the value can affect subsequent operations on the stack.
