IAM policies for calling Amazon SageMaker AI

The following example templates show how Amazon Step Functions generates IAM policies based on the resources in your state machine definition. For more information, see How Step Functions generates IAM policies for integrated services and Discover service integration patterns in Step Functions.

Note

For these examples, roleArn refers to the Amazon Resource Name (ARN) of the IAM role that SageMaker AI uses to access model artifacts and docker images for deployment on ML compute instances, or for batch transform jobs. For more information, see Amazon SageMaker Roles.
