--
-- Attaches one or more target groups to the specified Auto Scaling group.
--
-- This operation is used with the following load balancer types:
--
-- -   Application Load Balancer - Operates at the application layer (layer
--     7) and supports HTTP and HTTPS.
--
-- -   Network Load Balancer - Operates at the transport layer (layer 4)
--     and supports TCP, TLS, and UDP.
--
-- -   Gateway Load Balancer - Operates at the network layer (layer 3).
--
-- To describe the target groups for an Auto Scaling group, call the
-- DescribeLoadBalancerTargetGroups API. To detach the target group from
-- the Auto Scaling group, call the DetachLoadBalancerTargetGroups API.
--
-- This operation is additive and does not detach existing target groups or
-- Classic Load Balancers from the Auto Scaling group.
--
-- For more information, see
-- <https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group>
-- in the /Amazon EC2 Auto Scaling User Guide/.
