如何使用Terraform通过ASG使EC2实例的私有IP旋转

Question

为了从ASG获取IP，我尝试了以下代码，该IP是使用Terraform创建的？这是好习惯还是坏习惯？但是我得到了预期的正确输出。

data "aws_instances" "test" {
instance_tags {
Environment = "${var.environment}",
instance    = "${var.db_instance_name}"
}

instance_state_names = ["running"]


depends_on = ["aws_sqs_queue.ansible", "aws_autoscaling_group.sample"]
}

output.tf

output "privateips" {
  value = "${data.aws_instances.test.private_ips}"
}

创建ASG时，在末尾添加本地供应商以执行使用cli与AWS交互的本地脚本，以便您可以查询ASG IP：

grep "25/Jan/2019" access.log | aplogcsv > ~/20190125.access.log.csv

脚本：

resource "aws_autoscaling_group" "artifactory" {
  name_prefix          = "${var.env}-Application-ASG-"
  vpc_zone_identifier  = ["${var.app_subnets}"]
  max_size             = "${var.asg_max}"
  min_size             = "${var.asg_min}"
  desired_capacity     = "${var.asg_desired}"
  force_delete         = true
  launch_configuration = "${aws_launch_configuration.application.name}"
  target_group_arns    = ["${aws_alb_target_group.application.arn}"]

  provisioner "local-exec" {
    command = "./getips.sh"
  }
}
