UpdateStackTemplateByResources - API Reference| Alibaba Cloud Documentation Center

Before you call this operation, you must perform a successful drift detection operation on the stack, and the stack must be in the DRIFTED state. We recommend that you set the DryRun parameter to true to preview the corrected template. If the template content meets expectations, set the DryRun parameter to false to execute the correction.

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.

Request parameters


Parameter	Type	Required	Example	Description
Action	String	Yes	UpdateStackTemplateByResources	The operation that you want to perform. Set the value to UpdateStackTemplateByResources.
RegionId	String	Yes	cn-hangzhou	The region ID of the stack. You can call the DescribeRegions operation to query the most recent region list.
StackId	String	Yes	4a6c9851-3b0f-4f5f-b4ca-a14bf691****	The ID of the stack.
DryRun	Boolean	No	false	Specifies whether to only preview the corrected template in this request. Valid values: true: returns the content of the corrected template without correcting the template. After comparing the corrected template with the original template, Resource Orchestration Service (ROS) determines whether to execute the correction. false: corrects the template to eliminate drift. This is the default value.
ClientToken	String	No	123e4567-e89b-12d3-a456-42665544****	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 be up to 64 characters in length and can contain letters, digits, hyphens (-) and underscores (_). For more information, see How to ensure idempotence.
TemplateFormat	String	No	JSON	The format of the returned template. Default value: JSON. Valid values: JSON YAML
LogicalResourceId.N	RepeatList	No	Vpc	The logical ID of resource N, which is used to filter resources. Template correction takes effect only for resources in the list. By default, all resources that have drifted are corrected. If the list of corrected resources contains resources in the DELETED state, ROS may adjust the resources that are not in the list but reference the deleted resources in the list to ensure the correctness of the new template.

Response parameters


Parameter	Type	Example	Description
NewTemplateBody	String	See sample success responses	The template content after correction.
OldTemplateBody	String	See sample success responses	The template content before correction.
RequestId	String	B288A0BE-D927-4888-B0F7-B35EF84B6E6F	The ID of the request.

400	StackAlreadyInSync	This is not need to correct stack drifts, stack ({ID}) is already in sync.	The error message returned because no drift exists and the template correction is not needed. ID indicates the stack ID.
400	CorrectStackDriftsFailure	{reason}	The error message returned because the stack cannot be corrected. reason indicates the specific reason.
404	StackNotFound	The Stack ({name}) could not be found.	The error message returned because the specified stack does not exist. name indicates the name or ID of the stack.
404	ResourceNotFound	The Resource ({name}) could not be found in Stack {stack}.	The error message returned because the specified resource does not exist in the specified stack. name indicates the resource name, and stack indicates the stack name or ID.
