-- | 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'. 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, see <http://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html Managing UserPermissions>.
