此處不應使用名為“vpc_id”的參數

Question

我是 terraform 的新手。當我運行 terraform plan 時出現以下錯誤，

Error: Unsupported argument
> │
on 4_data_vpc.tf line 6, in data "aws_subnets" "subnets":
6:   vpc_id = data.aws_vpc.default_vpc.id
> │
An argument named "vpc_id" is not expected here.

這是 data_vpc.tf 文件

data "aws_vpc" "default_vpc" {
  default = true
}

# subnet list in the "default" VPC
# The "default" VPC has all "public subnets"
data "aws_subnet_ids" "default_public" {
  vpc_id = "${data.aws_vpc.default_vpc.id}"
}

我已將 aws_subnet_ids 更新為 aws_subnets，因為 aws_subnet_ids 數據源已被棄用

provider.tf文件

provider "aws" {
  region                  = "us-east-1"
  shared_credentials_file = "~/.aws/credentials"
  profile                 = "dev"
}

安全組.tf

# Security Group:
resource "aws_security_group" "jenkins_server" {
  name        = "jenkins_server"
  description = "Jenkins Server: created by Terraform for [dev]"

  # legacy name of VPC ID
  vpc_id = "${data.aws_vpc.default_vpc.id}"

  tags {
    Name = "jenkins_server"
    env  = "dev"
  }
}

當我在 data_vpc.tf 文件中聲明一個變量 vpc_id 並運行 terraform plan 時，終端要求我輸入一個值。

var.vpc_id
  Enter a value:

當您使用aws_subnets時，要添加vpc_id ，您必須使用filter塊：

data "aws_subnets" "subnets" {
   filter {
     name   = "vpc-id"
     values = [data.aws_vpc.default_vpc.id]
   }
}
