Create a stack by importing resources-Resource Orchestration Service(ROS)-阿里云帮助中心

Import an existing resource into a new stack for unified management. This topic uses an Elastic IP Address (EIP) as an example.

Scenarios

If you want to manage a large number of cloud resources at the same time, you can use resource import to add the cloud resources to a new stack. This way, you can use the stack to manage the cloud resources in a centralized manner and reduce manual intervention.

Prerequisites

Before you begin, complete the following:

Obtain the identifier property of the EIP resource.

In this example, the identifier property of the EIP resource is AllocationId, which is the instance ID of the EIP. For more information, see Obtain the identifier property of a resource to be imported.
Obtain the instance ID of the EIP.

Log on to the EIP console and obtain the instance ID of the EIP that you want to import.

Considerations

The resource in the template must include the DeletionPolicy property. Otherwise, the import fails. This property determines whether to retain the resource when its stack is deleted or the resource is removed from the stack. For more information, see DeletionPolicy property.

Procedure

Log on to the Resource Orchestration Service (ROS) console.
In the left-side navigation pane, click Stacks.
In the top navigation bar, select the region where you want to create the stack, such as China (Hangzhou).
On the Stacks page, click Import Resources.
On the Select Template page, under Specify Template, select Select an Existing Template. Set Template Import Method to Enter Template Content, enter the following YAML template in the Template Content field, and then click Next.
```
ROSTemplateFormatVersion: '2015-09-01'
Resources:
  Eip:
    Type: ALIYUN::VPC::EIP
    DeletionPolicy: Retain
    Properties:
      Bandwidth: 5
Outputs:
  EipAddress:
    Value:
      Fn::GetAtt:
        - Eip
        - EipAddress
  AllocationId:
    Value:
      Fn::GetAtt:
        - Eip
        - AllocationId
```
Note
DeletionPolicy: Set the value to Retain. This setting is required to prevent accidental resource deletion.
On the Configure Parameters page, configure Stack Name and Change Set Name.
In the Configure Stack Settings section, configure the parameters and click Next.

This example uses the default configurations. For more information, see Create a stack.
On the Identify Resources page, enter the resource identifier, such as eip-bp140qv3j25nsfaqd****, and click Next.
On the Compliance Precheck page, complete the compliance precheck and click Next.

For more information about compliance prechecks, see Compliance precheck.
On the Check and Confirm page, click Create Stack and Import Change Set.
On the Change Sets tab, find the change set and click Run in the Actions column to begin the resource import.
On the Stack Information tab, view the status of the stack.

A Status of Import completed. in the Basic information section indicates that the resource was imported successfully.
