instanceProfileArn
The ARN of the instance profile that your Amazon EC2 instances use. Although the AWS OpsWorks console typically creates the instance profile for you, if you are using API commands instead, run the service-role-creation.yaml AWS CloudFormation template, located at https://s3.amazonaws.com/opsworks-cm-us-east-1-prod-default-assets/misc/opsworks-cm-roles.yaml. This template creates a CloudFormation stack that includes the instance profile you need.
