如何针对单个 ECS 服务附加两个目标组

Question

我正在寻找一种方法来针对单个 ECS 服务附加两个目标组，在其他情况下，我的容器公开两个端口，但我只能将一个端口针对我的服务映射到 LB。

到目前为止，我能够创建一个新的侦听器和目标组，但在创建目标组后，我可以按照预期看到所有内容，但目标组显示There are no targets registered to this target group

这是我的目标组和侦听器配置

目标组：

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"
  }
}

听者： '

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"
  }
}

我的问题是如何添加 ECS 集群自动缩放组，或者如何将 ECS 集群中运行的所有实例添加到此目标组？

AWS最近宣布支持 ECS 服务的多个目标组。

目前未发布的AWS 提供商 2.22.0 版本load_balancer通过向资源添加更多块来提供对此的支持aws_ecs_service。验收测试示例：

resource "aws_ecs_service" "with_alb" {
  name            = "example"
  cluster         = "${aws_ecs_cluster.main.id}"
  task_definition = "${aws_ecs_task_definition.with_lb_changes.arn}"
  desired_count   = 1
  iam_role        = "${aws_iam_role.ecs_service.name}"

  load_balancer {
    target_group_arn = "${aws_lb_target_group.test.id}"
    container_name   = "ghost"
    container_port   = "2368"
  }

  load_balancer {
    target_group_arn = "${aws_lb_target_group.static.id}"
    container_name   = "ghost"
    container_port   = "4501"
  }

  depends_on = [
    "aws_iam_role_policy.ecs_service",
  ]
}
