terraform应用aws_spot_fleet_request时，如何检索私有ip地址？

Question

如果应用Terraform，则假设6个EC2实例作为目标容量，如此example中所示

# Request a Spot fleet
resource "aws_spot_fleet_request" "cheap_compute" {
  iam_fleet_role      = "arn:aws:iam::12345678:role/spot-fleet"
  spot_price          = "0.03"
  allocation_strategy = "diversified"
  target_capacity     = 6
  valid_until         = "2019-11-04T20:44:20Z"

  launch_specification {
    instance_type             = "m4.10xlarge"
    ami                       = "ami-1234"
    spot_price                = "2.793"
    placement_tenancy         = "dedicated"
    iam_instance_profile_arn  = "${aws_iam_instance_profile.example.arn}"
  }

  launch_specification {
    instance_type             = "m4.4xlarge"
    ami                       = "ami-5678"
    key_name                  = "my-key"
    spot_price                = "1.117"
    iam_instance_profile_arn  = "${aws_iam_instance_profile.example.arn}"
    availability_zone         = "us-west-1a"
    subnet_id                 = "subnet-1234"
    weighted_capacity         = 35

    root_block_device {
      volume_size = "300"
      volume_type = "gp2"
    }

    tags {
      Name = "spot-fleet-example"
    }
  }
}

唯一可用的属性是'id‘和'spot_request_state’。

如何输出启动实例的内网IP地址？

这是可能的吗?或者我需要使用另一个工具，如Boto3？

Answer 1

您可以在Terraform中使用Data Sources。这些允许您从本质上执行API调用以从AWS检索数据。一旦你创建了你的资源，你可以使用下面的Terraform -

data "aws_instances" "spot-fleet-ips" {
  instance_tags {
    Name = "spot-fleet-example"
  }
}

要获取IP地址，您可以执行以下操作-

"${data.aws_instances.spot-fleet-ips.private_ips}"

上述数据源的文档为here.

Answer 2

地面形式的自动柜员机不可能获得现货车队的实例。

您需要在AWS SDK / boto3中编写代码来查找使用Spot队列创建的实例。EC2 AutoScaling组和EMR集群也是如此。

谢谢。
