我正在尝试学习 terraform 模块的基础知识，这就是我在 terraform 中创建的资源、网络和计算模块，现在想将 vm_id 的输出传递给站点恢复模块，这是我目前正在使用的文件。

这是我目前正在关注的目录结构，

.
├── main.tf
├── variables.tf
├── terraform.tfvars
└── modules
    ├── instance
    │   ├── main.tf
    │   ├── outputs.tf
    │   ├── variable.tf

在 main.tf 中，我创建 aws_vpc 资源，这是我的实例模块的输入 下面的 main.tf 工作正常，我在 terraform 模块块中明确定义值

# Configure the AWS Provider
provider "aws" {
  region = "us-east-1"
}

# Create a VPC
resource "aws_vpc" "main" {
  cidr_block       = "10.0.0.0/16"
  instance_tenancy = "default"

  tags = {
    Name = "dev-vpc"
  }
}

output aws_vpc_id {
  value = aws_vpc.main.id
}

module myinstance {
  source = "./modules/instance"
  vpc_id = aws_vpc.main.id
  cidr_block = "10.0.0.0/24"
  map_public_ip_on_launch = true
  instance_name = "calypso"
  ami = "ami-09c92d3eb1db3a728"
  instance_type = "t3.micro"
}

但是，当我尝试将这些值移动到“terraform.tfvars”时，我的 terrafom 计划无法加载 vpc id 所以下面的 main.tf 无法从同一个 main.tf 中查找 vpc id

# Configure the AWS Provider
provider "aws" {
  region = "us-east-1"
}

# Create a VPC
resource "aws_vpc" "main" {
  cidr_block       = "10.0.0.0/16"
  instance_tenancy = "default"

  tags = {
    Name = "dev-vpc"
  }
}

output aws_vpc_id {
  value = aws_vpc.main.id
}

module "myinstance" {
  source                  = "./modules/instance"
  vpc_id                  = aws_vpc.main.id
  cidr_block              = var.cidr_block
  map_public_ip_on_launch = var.map_public_ip_on_launch
  instance_name           = var.instance_name
  ami                     = var.ami
  instance_type           = var.instance_type
}

我不太明白为什么第二种方法不起作用

---编辑1---所以这是我在运行有问题的main.tf terraform plan 或应用时得到的结果-由于某种原因，它无法检索在同一main.tf 中创建的vpc id

$ terraform plan
var.vpc_id       
  Enter a value:

这是我的变量.tf

variable "vpc_id" {
}
variable "cidr_block" {
  type        = string
  description = "cidr block for subnet"
}

variable "map_public_ip_on_launch" {
  type        = bool
  description = "if set to true, it will map public ip on launch"
  default     = true
}

variable "instance_name" {
  type        = string
  description = "name of your instance"
}

variable "ami" {
  type        = string
  description = "ami for your instance"
}

variable "instance_type" {
  type        = string
  description = "type of your instance"
}

这是我的 terraform.tfvars

cidr_block              = "10.0.0.0/24"
map_public_ip_on_launch = true
instance_name           = "calypso"
ami                     = "ami-09c92d3eb1db3a728"
instance_type           = "t3.micro"
