Terraform 要求提供 VPC ID，即使它隐含在子网中答案

【问题描述】：

我有以下简单的 EC2 创建地形脚本：

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.27"
    }
  }

  required_version = ">= 0.14.9"
}

provider "aws" {
  profile = "default"
  region  = "us-east-1" # virginia
}


resource "aws_network_interface" "network" {
  subnet_id       = "subnet-0*******"
  security_groups = ["sg-******"]

  attachment {
    instance     = aws_instance.general_instance.id
    device_index = 0
  }
}

resource "aws_instance" "general_instance" {
  ami           = "ami-00874d747dde814fa" # unbutu server
  instance_type = "m5.2xlarge"
  key_name      = "my-key"
  root_block_device {
    delete_on_termination = true
    volume_size           = 500
    tags                  = { Name = "Root Volume" }
  }
  # user_data = file("startup.sh") # file directive can install stuff
  tags = {
    Name = "General"
  }
}

我得到以下信息：

Error: Error launching source instance: VPCIdNotSpecified: No default VPC for this user. GroupName is only supported for EC2-Classic and default VPC.

我觉得这很奇怪，因为经典的流程是创建一个 VPC，创建一个子网，然后创建一个网络接口。但是，我有一个我想使用的 VPC，它与我正在使用的子网相关联。所以我想知道如果我将它与我请求的子网相关联，它会要求一个 VPC id。

【解决方案1】：

我已经想通了。

resource "aws_instance" "general_instance" {
  ami           = "ami-00874d747dde814fa" # unbutu server
  instance_type = "m5.2xlarge"
  key_name      = "EC2-foundry"

  network_interface {
    network_interface_id = aws_network_interface.network.id
    device_index         = 0
  }

  root_block_device {
    delete_on_termination = true
    volume_size           = 500
    tags                  = { Name = "Foundry Root Volume" }
  }
  # user_data = file("startup.sh") # file directive can install stuff
  tags = {
    Name = "Foundry General"
  }
}

网络接口必须附加在 aws 资源中
