Prepare to perform stack set operations in Amazon Web Services Regions that are disabled by default

Amazon Web Services Regions introduced after March 20, 2019, such as Asia Pacific (Hong Kong), are disabled by default. You must enable these Regions for your account(s) before you can use them. For more information, see Enable or disable Amazon Web Services Regions in your account in the Amazon Account Management Reference Guide.

To create a stack set from a stack set's administrator account (if using self-managed permissions) or organization's management account (if using service-managed permissions) in a Region that is disabled by default, you must first enable that Region for the administrator or management account.

For Amazon CloudFormation to successfully create or update a stack instance:

  • The target account must reside in a Region that's currently enabled for that target account.

  • The stack set's administrator account or organization's management account must have the same Region enabled as the target account.

Important

Be aware that during stack set operations, administrator and target accounts exchange metadata regarding the accounts themselves, in addition to the stack set and stack set instances involved.

In addition, if you disable a Region that contains an account in which stack set instances reside, you are responsible for deleting any such instances or resources, if desired. In addition, be aware that metadata regarding the target account in the disabled Region will be retained in the administrator account.
