使用Terraform在AWS中创建自动缩放组。

在Terraform的aws_autoscaling_group资源中使用mixed_instances_policy。

resource "aws_launch_template" "go_app" {
  image_id               = "${data.aws_ami.go_app.id}"
  instance_type          = "${var.launch_config["instance_type"]}"
  vpc_security_group_ids = ["${aws_security_group.go_app.id}"]
  key_name               = "${var.key_name}"
}

启动模板中的instance_type是t2.small。

resource "aws_autoscaling_group" "go_app" {
  name                 = "${aws_launch_template.go_app.name}-asg"
  vpc_zone_identifier  = ["${aws_subnet.public.*.id}"]

  min_size             = 1
  desired_capacity     = 2
  max_size             = 4

  mixed_instances_policy {
    launch_template {
      launch_template_specification {
        launch_template_id = "${aws_launch_template.go_app.id}"
        version            = "$$Latest"
      }
      override {
        instance_type = "t2.micro"
      }
      override {
        instance_type = "t2.nano"
      }
    }

    instances_distribution {
      on_demand_base_capacity                  = 1
      on_demand_percentage_above_base_capacity = 0
      spot_allocation_strategy                 = "lowest-price"
      spot_instance_pools                      = 2
    }
  }
}

这将创建1个按需实例和1个现货实例（由于所需容量为2）。但是它将创建1个按需实例，但无法创建竞价型实例。

“自动缩放”组的“活动历史记录”尝试创建实例，但出现以下错误：

Launching a new EC2 instance. Status Reason: Invalid fleet configuration. 
Overrides t2.nano, us-west-2c, LINUX. Launching EC2 instance failed.
