Terraform-从同一脚本填充变量值

我对地形很绿；事实上，这是我训练的一部分

我想知道；有没有办法让terraform在同一个文件中存储来自上一个命令的特定值（作为变量）

例如：

    resource "aws_vpc" "TestVPC"{
    cidr_block = "192.168.0.0/16"
    instance_tenancy = "default"
    enable_dns_hostnames="True"
    tags{
        Name="TestVpc"
    }
}
resource "aws_subnet" "TestSubnet"{
    vpc_id = "${var.aws_vpc_id}" ##This is where I'd like to populate the aws_vpc_id from the VPC creation step above.
    cidr_block = "192.168.0.0/24"
    map_public_ip_on_launch="True"
    availability_zone = "us-east-2a"
    tags{
        Name="TestSubnet"
    }
}

非常感谢您的帮助

谢谢。

您可以使用创建专有网络的输出，

${aws\u VPC.TestVPC.id}

像这样：

resource "aws_vpc" "TestVPC" {
  cidr_block           = "192.168.0.0/16"
  instance_tenancy     = "default"
  enable_dns_hostnames = "True"

  tags {
    Name = "TestVpc"
  }
}

resource "aws_subnet" "TestSubnet" {
  vpc_id                  = "${aws_vpc.TestVPC.id}"
  cidr_block              = "192.168.0.0/24"
  map_public_ip_on_launch = "True"
  availability_zone       = "us-east-2a"

  tags {
    Name = "TestSubnet"
  }
}
