-- Assign a registered instance to a layer.
--
-- -   You can assign registered on-premises instances to any layer type.
-- -   You can assign registered Amazon EC2 instances only to custom
--     layers.
-- -   You cannot use this action with instances that were created with AWS
--     OpsWorks.

-- __Required Permissions__: To use this action, an AWS Identity and Access
-- Management (IAM) user must have a Manage permissions level for the stack
