If you want to attach a autoscaling group to the target group, use <code>aws_autoscaling_attachment</code>,

You can add multiple define multiple target groups for the same ecs service using the <code>load_balancer</code> block.
<pre><code>resource &quot;aws_ecs_service&quot; &quot;ecs_service_1&quot; {
 name = &quot;service-1&quot;
 cluster = aws_ecs_cluster.ecs_cluster_prod.id
 task_definition = aws_ecs_task_definition.ecs_task_definition_1.arn
 desired_count = 1
 launch_type = &quot;FARGATE&quot;
 enable_execute_command = true

# Target group 1
 load_balancer {
 target_group_arn = aws_lb_target_group.lb_tg_1.arn
 container_name = &quot;app&quot;
 container_port = 8080
 }

# Target group 2
 load_balancer {
 target_group_arn = aws_lb_target_group.lb_tg_2.arn
 container_name = &quot;app&quot;
 container_port = 8080
 }

 network_configuration {
 subnets = [aws_subnet.subnet_a.id, aws_subnet.subnet_b.id]
 security_groups = [aws_security_group.sg_internal.id]
 assign_public_ip = true
 }

 tags = {
 Name = &quot;service-1&quot;
 ManagedBy = &quot;terraform&quot;
 Environment = &quot;prod&quot;
 }
}
</code></pre>
You can map the same container and port to both target groups in case of having an external and an internal load balancer for example

I am looking for a way to attach two target group against single ECS services, in other my container exposes two port but I am only able to map one port against my service to LB.

So far I am able to create a new listener and target group but after target group creation I can see everything as per expectation but the target group show <code>There are no targets registered to this target group</code>

<a href="https://i.stack.imgur.com/6JcT8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6JcT8.png" alt="enter image description here"></a>
Here are my target group and listener configuration

target_group:

<pre><code>resource "aws_lb_target_group" "e_admin" {
 name = "${var.env_prefix_name}-admin"
 port = 5280
 protocol = "HTTP"
 vpc_id = "${aws_vpc.VPC.id}"

 health_check {
 path = "/admin"
 healthy_threshold = 2
 unhealthy_threshold = 10
 port = 5280
 timeout = 90
 interval = 100
 matcher = "401,200"
 }
}
</code></pre>

Listener:'

<pre><code>resource "aws_lb_listener" "admin" {
 load_balancer_arn = "${aws_lb.admin_lb.arn}"
 port = "5280"
 protocol = "HTTP"

 default_action {
 target_group_arn = "${aws_lb_target_group.e_admin.id}"
 type = "forward"
 }
}
</code></pre>

My question is how I can add ECS cluster Autoscaling group or how I can add all the instances running in the ECS cluster to this target group?
