Replicate VPC Resources Across Regions Using ROS Template Scratch - Resource Orchestration Service - Alibaba Cloud - Resource Orchestration Service

Updates a scenario.

Operation description

Resource replication scenario

Resource Orchestration Service (ROS) allows you to update a resource replication scenario. The updates that you make to a resource replication scenario do not affect the stack that is generated by using the resource scenario. You can call the GenerateTemplateByScratch operation to generate a template for the resource scenario.

Resource migration scenario

If you want to update a resource migration scenario in which the migrated source resources are retained, you can delete the source resources to manage the updated resource migration scenario. You can also call the GenerateTemplateByScratch operation to generate a template for the resource scenario.

**

Note Make sure that the source resources that you want to delete from a resource migration scenario are associated only with the resource scenario. Otherwise, the source resources fail to be deleted.
If you want to update a resource migration scenario in which the migrated source resources are deleted, you can only call the GenerateTemplateByScratch operation to generate a template for the resource scenario.

Resource management scenario

If you want to update a resource management scenario after you use the resource scenario to manage resources, you can only call the GenerateTemplateByScratch operation to generate a template for the resource scenario.

Resource detection scenario

After you update a resource detection scenario, ROS obtains the most recent data from Resource Center and renders the architecture diagram.

This topic provides an example on how to update a resource scenario. In this example, the ID of a virtual private cloud (VPC) in a resource scenario whose ID is ts-7f7a704cf71c49a6**** is updated to vpc-bp1m6fww66xbntjyc****.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

ResourceGroupId	string	Yes	The ID of the source resource group.	rg-acfmzawhxxc****
ResourceTypeFilter	array	No	The resource types for filtering resources.
	string	No	The resource type for filtering resources. If you specify the resource types, ROS scans only the resources that are of the specified types and belong to the specified resource group. If you do not specify the resource types, ROS scans all resources that belong to the specified resource group. You can specify up to 20 resource types.	ALIYUN::ECS::VPC
PreferenceParameters	array<object>	No	The preference parameters of the resource scenario.
	object	No	The preference parameter of the scenario.
ParameterKey	string	Yes	The parameter name. For more information about the valid values of ParameterKey, see the "Additional information about request parameters" section of this topic. Note PreferenceParameters is optional. If you specify PreferenceParameters, you must specify both ParameterKey and ParameterValue. If you set TemplateScratchType to ResourceImport, you must set ParameterKey to DeletionPolicy.	DeletionPolicy
ParameterValue	string	Yes	The parameter value. The value of ParameterValue varies based on the value of ParameterKey.

Additional information about request parameters

For more information about common request parameters, see Common parameters.

The valid values of the ParameterKey and ParameterValue request parameters vary based on resource scenario types.

Resource replication scenario

The following table describes the valid values of the ParameterKey and ParameterValue request parameters when you set TemplateScratchId to the ID of a resource replication scenario.

ParameterKey	ParameterValue
DeletionPolicy	The deletion policy for resources. Valid values:Retain: retains resources when you delete the stack to which the resources are replicated.Delete: deletes resources by default when you delete the stack to which the resources are replicated. If you retain specific resources when the Delete Stack dialog box appears, the resources are retained.
RegionId	The ID of the destination region to which you want to replicate resources. If you leave this parameter empty, the region of the source resources is used for the replicated resources.Example: cn-shanghai.
ZoneId	The ID of the destination zone to which you want to replicate resources. If you replicate resources in the same region and you leave this parameter empty, the zone of the source resources is used for the replicated resources. If you replicate resources across regions and you leave this parameter empty, the system filters the zones that are supported by all resources.Example: cn-shanghai-b.
VpcId	The ID of the destination VPC to which you want to replicate resources. If you replicate resources in the same region and you leave this parameter empty, the VPC of the source resources is used for the replicated resources. If you replicate resources across regions and you leave this parameter empty, the system automatically creates a VPC in the destination region.Example: vpc-bp1hye0s8b69xokfu****.
VSwitchId	The ID of the destination vSwitch to which you want to replicate resources. If you replicate resources in the same region and you leave this parameter empty, the vSwitch of the source resources is used for the replicated resources. If you replicate resources across regions and you leave this parameter empty, the system automatically creates a vSwitch in the destination region.Example: vsw-bp11ufkwqwggtm1cj****.
InstanceDataReplication	Specifies whether to replicate Elastic Compute Service (ECS) instance data. Valid values:true: replicates ECS instance data. If you replicate the data in the same region, the system creates a custom image for the source instance and creates an instance based on the image. If you replicate the data across regions, the system creates a custom image for the source instance, replicates the image to the destination region, and then creates an instance based on the image.false: does not replicate ECS instance data.

Note If you set ParameterKey to InstanceDataReplication and ParameterValue to true, we recommend that you replicate resources after the source instance is stopped. This ensures data consistency.

Resource management scenario

The following table describes the valid values of the ParameterKey and ParameterValue request parameters when you set TemplateScratchId to the ID of a resource management scenario.

Note For a resource management scenario, you must set ParameterKey to DeletionPolicy.

ParameterKey	ParameterValue
DeletionPolicy	The deletion policy for resources. Valid values:Retain: retains resources when you delete the stack that you use to manage the resources.Delete: deletes resources by default when you delete the stack that you use to manage the resources. If you retain specific resources when the Delete Stack dialog box appears, the resources are retained.

Resource detection scenario

The following table describes the valid values of the ParameterKey and ParameterValue request parameters when you set TemplateScratchId to the ID of a resource detection scenario.

ParameterKey	ParameterValue
RegionIds	One or more region IDs. Separate multiple region IDs with commas (,). If you leave this parameter empty, the region of the resource scenario is used. You cannot specify both RegionIds and SourceResources.
