如何使用Terraform创建ECS集群实例

Question

我正在使用Terraform设置新的ECS集群。 创建群集本身时，如何使用terraform启动ecs群集实例。 谁能使用terraform资源帮助我编写脚本

resource "aws_ecs_cluster" "core-ecs-cluster" {
   name = "${var.ecs_cluster}"  
   #launch_type = "EC2"

}

resource "aws_ecs_task_definition" "app" {
  family                = "app"
  container_definitions = "${file("ecs/service.json")}"
  requires_compatibilities = ["EC2"]

  volume {
    name      = "service-storage"
    host_path = "/ecs/service-storage"
  }

  placement_constraints {
    type       = "memberOf"
    expression = "attribute:ecs.availability-zone in [ap-south-1a, ap-south-1b]"
  }
}

resource "aws_ecs_service" "mds" {
  name            = "mds"
  cluster         = "${aws_ecs_cluster.core-ecs-cluster.id}"
  task_definition = "${aws_ecs_task_definition.task-def-service.family}:${max("${aws_ecs_task_definition.task-def-service.revision}")}"
  desired_count   = 1
  #iam_role        = "${aws_iam_role.ecs-service-role-1.arn}"
  #depends_on      = ["aws_iam_role_policy.ecs-service-role"]
  launch_type     = "EC2"

  ordered_placement_strategy {
    type  = "binpack"
    field = "cpu"
  }

  load_balancer {
    target_group_arn = "${aws_alb_target_group.ecs-target-group.arn}"
    container_name   = "core-v2-test"
    container_port   = 3000
  }

  placement_constraints {
    type       = "memberOf"
    expression = "attribute:ecs.availability-zone in [ap-south-1a, ap-south-1b]"
  }
}
