云防火墙：配置互联网访问控制策略

前提条件

• 已创建阿里云账号和访问密钥（AccessKey）。具体操作，请参见创建AccessKey。

• 已经安装并配置了Terraform。具体操作，请参见在Cloud Shell中使用Terraform或在本地安装和配置Terraform。

注意事项

• Terraform运行环境：阿里云Cloud Shell

• Terraform版本：0.12

• alicloud版本：1.203.0

• resource定义：alicloud_cloud_firewall_control_policy

配置互联网访问控制策略

1. 在Terraform执行目录下的terraform.tf文件中，配置如下内容。

   代码示例如下：

   provider "alicloud" {
     version = "~> 1.203.0"
   }
   
   resource "alicloud_cloud_firewall_control_policy" "example" {
     application_name = "ANY"
     acl_action       = "accept"
     description      = "Created_by_terraform"
     destination_type = "net"
     destination      = "100.1.XX.XX/24"
     direction        = "out"
     proto            = "ANY"
     source           = "1.2.XX.XX/24"
     source_type      = "net"
   }

2. 运行terraform init，对环境进行初始化。

   代码示例如下：

   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.

3. 运行terraform apply。出现如下配置信息后，确认配置信息并输入yes，开始创建。

   代码示例如下，创建成功后，可以返回访问控制策略ID为1b5f9953-0a00-46d6-8282-0cf08ff5****，方向为出方向（out）。

   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:
   
     # alicloud_cloud_firewall_control_policy.example will be created
     + resource "alicloud_cloud_firewall_control_policy" "example" {
         + acl_action       = "accept"
         + acl_uuid         = (known after apply)
         + application_name = "ANY"
         + description      = "Created_by_terraform"
         + dest_port        = (known after apply)
         + dest_port_group  = (known after apply)
         + dest_port_type   = (known after apply)
         + destination      = "100.1.1.0/24"
         + destination_type = "net"
         + direction        = "out"
         + id               = (known after apply)
         + proto            = "ANY"
         + release          = (known after apply)
         + source           = "1.2.3.0/24"
         + source_ip        = (known after apply)
         + source_type      = "net"
       }
   
   Plan: 1 to add, 0 to change, 0 to destroy.
   
   Do you want to perform these actions?
     Terraform will perform the actions described above.
     Only 'yes' will be accepted to approve.
   
     Enter a value: yes
   
   alicloud_cloud_firewall_control_policy.example: Creating...
   alicloud_cloud_firewall_control_policy.example: Creation complete after 0s [id=1b5f9953-0a00-46d6-8282-0cf08ff5****:out]

4. 查看结果。

   • 运行terraform show查看访问控制策略的详细信息。

     # alicloud_cloud_firewall_control_policy.example:
     resource "alicloud_cloud_firewall_control_policy" "example" {
      acl_action = "accept"
      acl_uuid = "1b5f9953-0a00-46d6-8282-0cf08ff5****"
      application_name = "ANY"
      description = "Created_by_terraform"
      dest_port = "0/0"
      dest_port_type = "port"
      destination = "100.1.XX.XX/24"
      destination_type = "net"
      direction = "out"
      id = "1b5f9953-0a00-46d6-8282-0cf08ff5****:out"
      proto = "ANY"
      release = "true"
      source = "1.2.XX.XX/24"
      source_type = "net"
     }
