Add Stacks to a Stack Set

When you create a stack set, you can create the stacks for that stack set. AWS CloudFormation also enables you to add more stacks, for additional accounts and regions, at any point after the stack set is created. You can add stack instances using either the AWS Management Console, or by using AWS CloudFormation commands in the AWS CLI. In this procedure, we will add stack instances for an additional region to the stack set we created in Create a New Stack Set.

To add stacks to a stack set by using the AWS Management Console

  1. Open the AWS CloudFormation console at

  2. At the top of the page, choose StackSets. On the StackSets home page, select the stack set that you created in Create a New Stack Set. In this walkthrough, we created a stack set named my-awsconfig-stackset.

  3. With the stack set selected, choose Manage stacks in stack set from the Actions menu.

  4. Choose Create stacks, and then choose Next.

  5. On the Set deployment options page, in the Accounts area, choose Create stacks from account.

  6. In the Create stacks from account text box, paste all target account IDs that you used to create your stack set in Create a New Stack Set.

  7. In the Regions area, choose US West (N. California), and then choose Add. You will be creating new stacks, in the US West (N. California) region, for the accounts you've specified.

  8. In the Preferences area, leave the default value of 1 and By number for Maximum concurrent accounts, and change the value of Failure tolerance to 1. Be sure Failure tolerance is also set to By number. Choose Next.

  9. On the Set overrides page, leave the property values as specified. You won't be overriding any property values for the stacks you're going to create. Choose Next.

  10. On the Review page, review your choices and your stacks' properties. To make changes, choose Edit in the area in which you want to change properties. When you are are ready to create your stacks, choose Create stacks.

  11. AWS CloudFormation starts creating your stacks. View the progress and status of the creation of the stacks in your stack set in the Properties page that opens when you choose Create stacks.
