AWS CloudFormation now supports StackSets Resource Type in the CloudFormation Registry
AWS CloudFormation has expanded the CloudFormation Registry to include the StackSets resource type. StackSets is a CloudFormation feature that allows you to centrally manage deployment of cloud resources to multiple AWS accounts and regions in a single operation. You can now model, provision, and manage your stack sets resources alongside other AWS resources through CloudFormation in a predictable and reliable way.
With StackSets included as a resource type in the CloudFormation Registry, you can use CloudFormation features such as resource import to bring your existing stack sets into CloudFormation’s management and then leverage CloudFormation functionalities such as intrinsic functions and resource attributes to manage your stack sets resources. Using StackSets, you can extend the functionality of CloudFormation by centrally creating, updating, or deleting CloudFormation supported resources across multiple AWS accounts and regions. For example, you can deploy your centralized AWS Identity and Access Management (IAM) roles and provision Amazon Elastic Compute Cloud (EC2) instances across AWS accounts and regions in a single operation. The source code for the StackSets resource type is now publicly available on GitHub, enabling the community to provide feedback and contribute enhancements.
You can provision stack sets resources using CloudFormation in the following AWS Regions: US East (Ohio, N. Virginia), US West (N. California, Oregon), Asia Pacific (Mumbai, Seoul, Singapore, Sydney, Tokyo), Canada (Central), Europe (Frankfurt, Ireland, London, Paris) and South America (Sao Paulo).
