-- Attaches an Elastic Load Balancing load balancer to a specified layer. AWS OpsWorks Stacks does not support Application Load Balancer. You can only use Classic Load Balancer with AWS OpsWorks Stacks. For more information, see <http://docs.aws.amazon.com/opsworks/latest/userguide/layers-elb.html Elastic Load Balancing> .
