AWS CloudFormation StackSets and AWS Organizations
AWS CloudFormation StackSets enables you to create, update, or delete stacks across multiple AWS accounts and AWS Regions with a single operation. StackSets integration with AWS Organizations enables you to create stack sets with service-managed permissions, using a service-linked role that has the relevant permission in each member account. This lets you deploy stack instances to member accounts in your organization. You don't have to create the necessary AWS Identity and Access Management roles; StackSets creates the IAM role in each member account on your behalf. You can also choose to enable automatic deployments to accounts that are added to your organization in the future.
With trusted access between StackSets and Organizations enabled, the management account has permissions to create and manage stack sets for your organization. The management account can register up to five member accounts as delegated administrators. With trusted access enabled, delegated administrators also have permissions to create and manage stack sets for your organization. Stack sets with service-managed permissions are created in the management account, including stack sets that are created by delegated administrators.
Delegated administrators have full permissions to deploy to accounts in your organization. The management account cannot limit delegated administrator permissions to deploy to specific OUs or to perform specific stack set operations.
For more information about integrating StackSets with Organizations, see Working with AWS CloudFormation StackSets in the AWS CloudFormation User Guide.
Use the following information to help you integrate AWS CloudFormation StackSets with AWS Organizations.
Service-linked roles created when you enable integration
The following service-linked role is automatically created in your organization's accounts when you enable trusted access. These roles allow AWS CloudFormation Stacksets to perform supported operations within the accounts in your organization.
You can delete or modify these roles only if you disable trusted access between AWS CloudFormation Stacksets and Organizations, or if you remove the member account from the organization.

Management account:
CloudFormationStackSetsOrgAdmin -
Member accounts:
CloudFormationStackSetsOrgMember
Service principals used by the service-linked roles
The service-linked roles in the previous section can be assumed only by the service principals authorized by the trust relationships defined for the role. The service-linked roles used by AWS CloudFormation Stacksets grant access to the following service principals:
-
Management account:
stacksets.cloudformation.amazonaws.comYou can modify or delete this role only if you disabled trusted access between StackSets and Organizations.
-
Member accounts:
member.org.stacksets.cloudformation.amazonaws.comYou can modify or delete this role from an account only if you first disable trusted access between StackSets and Organizations, or if you first remove the account from the target organization or organizational unit (OU).
Enabling trusted access with AWS CloudFormation Stacksets
For information about the permissions needed to enable trusted access, see Permissions required to enable trusted access.
Only an administrator in the Organizations management account has permissions to enable trusted access with another AWS service. You can enable trusted access using either the AWS CloudFormation console or the Organizations console.
You can enable trusted access using only the AWS CloudFormation StackSets console or tools.
To enable trusted access using the AWS CloudFormation Stacksets console, see Enable Trusted Access with AWS Organizations in the AWS CloudFormation User Guide.
Disabling trusted access with AWS CloudFormation Stacksets
For information about the permissions needed to disable trusted access, see Permissions required to disable trusted access.
Only an administrator in an Organizations management account has permissions to disable trusted access with another AWS service. You can disable trusted access only by using the Organizations console. If you disable trusted access with Organizations while you are using StackSets, all previously created stack instances are retained. However, stack sets deployed using the service-linked role's permissions can no longer perform deployments to accounts managed by Organizations.
You can disable trusted access using only the Organizations console or tools.
You can disable trusted access by using either the AWS Organizations console, by running an Organizations AWS CLI command, or by calling an Organizations API operation in one of the AWS SDKs.
Enabling a delegated administrator account for AWS CloudFormation Stacksets
When you designate a member account as a delegated administrator for the organization, users and roles from that account can perform administrative actions for AWS CloudFormation Stacksets that otherwise can be performed only by users or roles in the organization's management account. This helps you to separate management of the organization from management of AWS CloudFormation Stacksets.
For instructions on how to designate a member account as a delegated administrator of AWS CloudFormation Stacksets in the organization, see Register a delegated administrator in the AWS CloudFormation User Guide.
