如何建立VPC邊界防火牆 - Cloud Firewall

本文介紹如何使用Terraform建立VPC邊界防火牆（防護通過Express Connect串連的兩個VPC之間的流量）。

注意事項

Terraform運行環境：阿里雲Cloud Shell
Terraform版本：0.12
alicloud版本：1.203.0
resource定義：cloud_firewall_vpc_firewall

前提條件

已建立阿里雲帳號和存取金鑰（AccessKey）。具體操作，請參見建立AccessKey。
已經安裝並配置了Terraform。

建立VPC邊界防火牆

在Terraform執行目錄下的terraform.tf檔案中，配置如下內容。

程式碼範例如下：

provider "alicloud" {
  version = "~> 1.203.0"
}

resource "alicloud_cloud_firewall_vpc_firewall" "default" {
  vpc_firewall_name = "tf-test"
  member_uid        = "141518928482****"
  local_vpc {
    vpc_id    = "vpc-bp1d065m6hzn1xbw8****"
    region_no = "cn-hangzhou"
    local_vpc_cidr_table_list {
      local_route_table_id = "vtb-bp1lj0ddg846856ch****"
      local_route_entry_list {
        local_next_hop_instance_id = "ri-bp1uobww3aputjlww****"
        local_destination_cidr     = "10.XX.XX.0/16"
      }
    }
  }
  peer_vpc {
    vpc_id    = "vpc-bp1gcmm64o3caox84****"
    region_no = "cn-hangzhou"
    peer_vpc_cidr_table_list {
      peer_route_table_id = "vtb-bp1f516f2hh4sok1i****"
      peer_route_entry_list {
        peer_destination_cidr     = "10.XX.XX.0/16"
        peer_next_hop_instance_id = "ri-bp1thhtgf6ydr2or5****"
      }
    }
  }
  status = "open"
}

運行terraform init，對環境進行初始化。

程式碼範例如下：

Initializing the backend...

Initializing provider plugins...
- Checking for available provider plugins...
- Downloading plugin for provider "alicloud" (hashicorp/alicloud) 1.203.0...


Warning: registry.terraform.io: For users on Terraform 0.13 or greater, this provider has moved to aliyun/alicloud. Please update your source in required_providers.


Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

運行terraform apply。出現如下配置資訊後，確認配置資訊並輸入yes，開始建立。

程式碼範例如下，建立成功後，可以返回VPC邊界防火牆ID為vfw-d7b8ce273791475b****。

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:
