如何使用 Terraform 标记从自动缩放启动的实例？

Question

我正在使用 Terraform 设置 ECS 集群。这是我的启动配置：

resource "aws_launch_configuration" "launch_config" {
  name_prefix = "my_project_lc"
  image_id = "ami-ff15039b"
  instance_type = "t2.medium"
  user_data = "${data.template_file.user_data.rendered}"
  lifecycle {
    create_before_destroy = true
  }
}

resource "aws_autoscaling_group" "autoscaling_group" {
  name = "my_project_asg"
  max_size = 2
  min_size = 1
  launch_configuration = "${aws_launch_configuration.launch_config.name}"
  vpc_zone_identifier = ["${aws_subnet.public.id}"]
}

它工作正常，但 EC2 实例没有名称（标签“名称”）。如何更改我的配置以便为实例提供有意义的名称？前缀什么的...

谢谢

对的，这是可能的。aws_autoscaling_group请参阅资源文档。示例代码：

resource "aws_autoscaling_group" "bar" {
  name = "my_project_asg"
  max_size = 2
  min_size = 1
  launch_configuration = "${aws_launch_configuration.launch_config.name}"
  vpc_zone_identifier = ["${aws_subnet.public.id}"]

  tag {
    key                 = "Name"
    value               = "something-here"
    propagate_at_launch = true
  }

  tag {
    key                 = "lorem"
    value               = "ipsum"
    propagate_at_launch = false
  }
}

或者，您可以使用terraform-aws-autoscaling模块来实现不同类型的标签。
