使用Terraform管理云备份资源

前提条件

• 由于阿里云账号（主账号）具有资源的所有权限，一旦发生泄露将面临重大风险。建议您使用RAM用户，并为该RAM用户创建AccessKey，具体操作方式，请参见创建RAM用户和创建AccessKey。

• 使用以下示例为RAM用户授权，需要为该RAM用户授予以下权限：管理云备份资源AliyunHBRFullAccess的权限。具体操作方式请参见为RAM用户授权。

• 准备Terraform运行环境，您可以选择以下任一方式来使用Terraform。

  在Terraform Explorer中使用Terraform：阿里云提供了Terraform的在线运行环境，您无需安装Terraform，登录后即可在线使用和体验Terraform。适用于零成本、快速、便捷地体验和调试Terraform的场景。

  Cloud Shell：阿里云Cloud Shell中预装了Terraform的组件，并已配置好身份凭证，您可直接在Cloud Shell中运行Terraform的命令。适用于低成本、快速、便捷地访问和使用Terraform的场景。

  在本地安装和配置Terraform：适用于网络连接较差或需要自定义开发环境的场景。

使用的资源

alicloud_hbr_vault：创建备份库。

使用Terraform创建一个云备份的备份库

本示例将创建一个云备份的备份库。

1. 创建一个工作目录，并且在工作目录中创建以下名为main.tf的配置文件。main.tfTerraform主文件，定义了将要部署的资源。

   variable "region" {
     default = "cn-hangzhou"
   }
   provider "alicloud" {
     region = var.region
   }
   resource "random_integer" "default" {
     min = 10000
     max = 99999
   }
   # 创建云备份库
   resource "alicloud_hbr_vault" "example" {
     vault_name = "example_value_${random_integer.default.result}"
   }

2. 执行以下命令，初始化Terraform运行环境。

   terraform init

   返回如下信息，表示Terraform初始化成功。

   Initializing the backend...
   
   Initializing provider plugins...
   - Finding latest version of hashicorp/alicloud...
   - Installing hashicorp/alicloud v1.234.0...
   - Installed hashicorp/alicloud v1.234.0 (signed by HashiCorp)
   
   Terraform has created a lock file .terraform.lock.hcl to record the provider
   selections it made above. Include this file in your version control repository
   so that Terraform can guarantee to make the same selections by default when
   you run "terraform init" in the future.
   
   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. 创建执行计划，并预览变更。

   terraform plan

4. 执行以下命令，创建一个云备份的备份库。

   terraform apply

   在执行过程中，根据提示输入yes并按下Enter键，等待命令执行完成，若出现以下信息，则表示创建云备份的备份库成功。

   Plan: 2 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
   
   random_integer.default: Creating...
   random_integer.default: Creation complete after 0s [id=58472]
   alicloud_hbr_vault.example: Creating...
   alicloud_hbr_vault.example: Creation complete after 8s [id=v-00023xlq3mjub7****]
   
   Apply complete! Resources: 2 added, 0 changed, 0 destroyed.

5. 验证结果

   执行terraform show命令

   您可以使用以下命令查询Terraform已创建的资源详细信息：

   terraform show

   

   登录云备份控制台

   创建完成后，您可以通过OpenAPI、SDK或者在云备份控制台，可以查看到创建的备份库。

   

清理资源

当您不再需要上述通过Terraform创建或管理的资源时，请运行以下命令以释放资源。关于terraform destroy的更多信息，请参见Terraform常用命令。

terraform destroy
