-- | The stack AWS Identity and Access Management (IAM) role, which allows AWS
-- OpsWorks to work with AWS resources on your behalf. You must set this
-- parameter to the Amazon Resource Name (ARN) for an existing IAM role. For
-- more information about IAM ARNs, see <http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_Identifiers.html Using Identifiers>.
--
-- You must set this parameter to a valid service role ARN or the action will
-- fail; there is no default value. You can specify the stack's current service
-- role ARN, if you prefer, but you must do so explicitly.
