从 ASG 获取私人 IP

Question

我需要 output private IP 来自 EC2 实例的 Auto Scaling Group，该实例由 Terraform 配置。如何从 ASG 获得私有 IP？

 # Launch config for ASG resource "aws_launch_configuration" "asg_conf" { name = "ASG-Conf-${var.env}" image_id = data.aws_ami.ubuntu.id # Get image from data instance_type = var.instance_type # use t2.micro ad default security_groups = [var.sg_app.id, var.sg_alb.id] # SG for APP key_name = var.ssh_key # SSH key for connection to EC2 user_data = file("./modules/ec2/shell/apache.sh") # install apache lifecycle { create_before_destroy = true } } # Auto Scaling Group resource "aws_autoscaling_group" "asg" { count = length(var.private_su.net_id) # count numbers of private su.nets name = "ASG-${var.env}-${count.index + 1}" vpc_zone_identifier = [var.private_su.net_id[count.index]] launch_configuration = aws_launch_configuration.asg_conf.name target_group_arns = [var.alb_target.arn] min_size = 1 # Min size of creating EC2 max_size = 1 # Max size of creating EC2 health_check_grace_period = 120 health_check_type = "ELB" force_delete = true lifecycle { create_before_destroy = true } tag { key = "Name" value = "Webserver-ec2-${count.index + 1}" propagate_at_launch = true } } output { # How can i get this??? value = aws_autoscaling_group.asg.private_ip }

我的基础设施通过 ASG 在 2 个私有 AZ 中创建 1 个 EC2 实例，我需要来自这个 ASG 的 output IP

您需要自定义数据源来获取 IP。 但这真的没有多大意义，因为 ASG 中的实例可以随时被 AWS 更改，从而使您的 IP 过时。
