-- Assigns one of the stack\'s registered Amazon EBS volumes to a specified
-- instance. The volume must first be registered with the stack by calling
-- RegisterVolume. After you register the volume, you must call
-- UpdateVolume to specify a mount point before calling 'AssignVolume'. For
-- more information, see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/resources.html Resource Management>.
--
-- __Required Permissions__: To use this action, an IAM user must have a
-- Manage permissions level for the stack, or an attached policy that
-- explicitly grants permissions. For more information on user permissions,
