Attach Load Balancer Target Groups

autoscaling_attach_load_balancer_target_groups R Documentation

This API operation is superseded by AttachTrafficSources, which can attach multiple traffic sources types

Description

This API operation is superseded by attach_traffic_sources, which can attach multiple traffic sources types. We recommend using attach_traffic_sources to simplify how you manage traffic sources. However, we continue to support attach_load_balancer_target_groups. You can use both the original attach_load_balancer_target_groups API operation and attach_traffic_sources on the same Auto Scaling group.

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 describe_load_balancer_target_groups API. To detach the target group from the Auto Scaling group, call the detach_load_balancer_target_groups 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 Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

Usage

autoscaling_attach_load_balancer_target_groups(AutoScalingGroupName,
  TargetGroupARNs)

Arguments

AutoScalingGroupName

[required] The name of the Auto Scaling group.

TargetGroupARNs

[required] The Amazon Resource Names (ARNs) of the target groups. You can specify up to 10 target groups. To get the ARN of a target group, use the Elastic Load Balancing DescribeTargetGroups API operation.

Value

An empty list.
