Terraform - 未在根模块中声明托管资源

Question

我正在尝试使用 terraform 创建 ec2 实例并设置负载均衡器，但我面临以下错误。如何在单个 main.tf 文件中创建实例和配置负载均衡器？

Error: Reference to undeclared resource

"aws_lb_target_group" "front-end":27: vpc_id = "${aws_vpc.terrafom-elb.id}"A managed resource "aws_vpc" "terrafom-elb" has not been declared in the rootmodule.source`

代码:

  region = "us-east-1"
  access_key = "*********************"
  secret_key = "**********************"
}

resource "aws_instance" "terraform" {
  ami           = "ami-07ebfd5b3428b6f4d"
  instance_type = "t2.micro"
  security_groups    = ["nodejs","default"]
  tags = {
    Name = "terrafom-elb"
  }
}

resource "aws_lb" "front-end"{
  name = "front-end-lb"
  internal = false
  security_groups    = ["nodejs"]

}

resource "aws_lb_target_group" "front-end" {
  name     = "front-end"
  port     = 8989
  protocol = "HTTP"
  vpc_id   = "${aws_vpc.terrafom-elb.id}"
  depends_on = [aws_instance.terraform]
}

您可以添加 data结构到顶部并将 VPC ID 作为变量传递:

data "aws_vpc" "selected" {
  id = var.vpc_id
}

并将其引用为 vpc_id = data.aws_vpc.selected.id
