Question

我在terraform中遇到模块根级别输出的一些奇怪问题。

我们在根级别的outputs.tf中有以下内容：

output "vpc_id" {
  value = "${aws_vpc.vpc.id}"
}

在模块中我们有

resource "aws_vpc" "vpc" {
  cidr_block = "${var.vpc_cidr}"
  enable_dns_hostnames = true
  tags {
      Name = "${upper(var.env)}-TF"
      env = "${var.env}"
      managed = "Terraform"
  }
}

然而，当运行计划terraform错误时，解析输出块并在跟踪上显示：

2017/01/31 17:56:54 [INFO] Terraform version: 0.8.0  142dd256ad48ab17b6019fe9cd18712167fcf4b4

此刻我不知所措。我到处寻找，无处可寻，甚至没有找到我们为什么会遇到这个错误。

啊，问题在于：

output "vpc_id" {
  value = "${aws_vpc.vpc.id}"
}

定义根级别输出时，您需要这样做：

output "vpc_id_root" {
  value = "${module.networking.vpc_id}"
}

Terraform Root Level输出问题
