简介：
本文介绍如何使用Terraform创建专有网络，交换机以及NAT网关。
操作步骤
- 创建专有网络和交换机。
- 创建terraform.tf文件，输入以下内容，并保存在当前在当前的执行目录中。
provider "alicloud" {
configuration_source = "terraform-provider-alicloud/examples/vpc"
}
resource "alicloud_vpc" "main" {
name = var.long_name
cidr_block = var.vpc_cidr
}
resource "alicloud_vswitch" "main" {
vpc_id = alicloud_vpc.main.id
count = length(var.cidr_blocks)
cidr_block = var.cidr_blocks["az${count.index}"]
availability_zone = var.availability_zones
depends_on = [alicloud_vpc.main]
}
- 运行terraform apply开始创建。出现类似下面的日志，说明创建成功。

- 运行terraform show查看已创建的专有和专有网络。
- 创建NAT网关。
- 在terraform.tf文件中增加以下内容：
resource "alicloud_nat_gateway" "main" {
vpc_id = alicloud_vpc.main.id
specification = "Small"
name = "from-tf-example"
}
resource "alicloud_eip" "foo" {
}
resource "alicloud_eip_association" "foo" {
allocation_id = alicloud_eip.foo.id
instance_id = alicloud_nat_gateway.main.id
}
- 运行terraform apply开始创建。出现下面的日志，说明创建成功。
