Create VPCs with the same configuration in multiple regions in an Alibaba Cloud account - Resource Orchestration Service

Prerequisites

If you use the self-managed permission model to create a stack group, create an administrator account and one or more execution accounts, and manually create RAM roles in both to establish a trust relationship. For more information, see Authorize self-managed permissions.
If you use the service-managed permission model to create a stack group, configure a delegated administrator account. For more information, see Set up a delegated administrator account.

The Parameters section lets you specify the VPC name and CIDR block when you create stack instances.
The Resources section defines the VPC resource.
The Outputs section returns the created VPC ID through VpcId.

Step 2: Create a stack group

Log on to the Resource Orchestration Service (ROS) console.
In the navigation pane on the left, click Stack Groups.
In the top navigation bar, select the region for the stack group from the drop-down list.
On the Stack Groups page, click Create Stack Group.
On the Select Template page, choose to use an existing template, set Template Import Method to Enter Template Content, and enter the YAML template from Step 1: Prepare a template.
On the Configure Parameters page, enter the Stack Group Name and Stack Group Description, configure the VPC parameters, and then click Next.
On the Configure Stack Group page, set the Permission Model to Service-managed Permissions or Self-managed Permissions, and then click Next.

For more information, see permission models.
On the Set Deployment Options page, configure the deployment parameters, and then click Next.
- When you use the service-managed permission model to create a stack group, you select a member in the Resource Directory for Deployment Destinations and select multiple regions.
  
  Configure other parameters as needed. For more information, see Create a stack group by using the service-managed permission model.
- When you use the self-managed permission model to create a stack group, for Deployment Locations, select Deploy Stacks Within Accounts, add an account, and select multiple regions.
  
  Configure other parameters as needed. For more information, see Create a stack group by using the self-managed permission model.
Note
You can select a maximum of 20 regions.
On the Check and Confirm page, verify the stack group information and click Create Stack Group.

Step 3: View the stack group

In the left navigation pane, click Stack Groups.
On the Stack Groups page, click the target Stack Group Name.
Click the Instance tab to view the created stack instances and their corresponding stack IDs.
Click a Stack ID. On the Resources tab, view the VPC information.

CREATE_COMPLETE in the Status column confirms that the VPC was created.
