操作步驟

1. 打開瀏覽器，訪問Cloud Shell。

   說明

   更多Cloud Shell入口及使用請參見使用云命令行。

   

2. 創建執行目錄并進入。

   說明

   需要為每個Terraform項目創建一個獨立的執行目錄。

   mkdir /usr/local/terraform
   cd /usr/local/terraform

3. 使用vim編寫Terraform模板（terraform.tf）。

   以查詢可用區信息為例：

   vim terraform.tf

   模板內容如下：

   data "alicloud_db_zones" "queryzones" {
     instance_charge_type= "PostPaid"
     engine = "PostgreSQL"
     db_instance_storage_type = "cloud_essd"
   }

   說明

   vim命令配置完成后，需按Esc后輸入:wq保存退出。

4. 執行terraform init命令初始化配置。

   執行結果示例：

   shell@Alicloud:/usr/local/terraform$ terraform init
   
   Initializing the backend...
   
   Initializing provider plugins...
   - Checking for available provider plugins...
   - Downloading plugin for provider "alicloud" (hashicorp/alicloud) 1.186.0...
   
   The following providers do not have any version constraints in configuration,
   so the latest version was installed.
   
   To prevent automatic upgrades to new major versions that may contain breaking
   changes, it is recommended to add version = "..." constraints to the
   corresponding provider blocks in configuration, with the constraint strings
   suggested below.
   
   * provider.alicloud: version = "~> 1.186"
   
   
   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.

5. 執行terraform plan命令預覽配置。

   執行結果示例：

   shell@Alicloud:/usr/local/terraform$ terraform plan
   Refreshing Terraform state in-memory prior to plan...
   The refreshed state will be used to calculate this plan, but will not be
   persisted to local or remote state storage.
   
   data.alicloud_db_zones.queryzones: Refreshing state...
   
   ------------------------------------------------------------------------
   
   No changes. Infrastructure is up-to-date.
   
   This means that Terraform did not detect any differences between your
   configuration and real physical resources that exist. As a result, no
   actions need to be performed.

6. 執行terraform apply應用配置。

   執行結果示例：

   shell@Alicloud:/usr/local/terraform$ terraform apply
   data.alicloud_db_zones.queryzones: Refreshing state...
   
   Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

7. 執行terraform show查看查詢結果。

   執行結果示例：

   shell@Alicloud:/usr/local/terraform$ terraform show
   # data.alicloud_db_zones.queryzones:
   data "alicloud_db_zones" "queryzones" {
       db_instance_storage_type = "cloud_essd"
       engine                   = "PostgreSQL"
       id                       = "491248936"
       ids                      = [
           "cn-hangzhou-g",
           "cn-hangzhou-j",
           "cn-hangzhou-k",
       ]
       instance_charge_type     = "PostPaid"
       multi                    = false
       multi_zone               = false
       zones                    = [
           {
               id             = "cn-hangzhou-g"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-j"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-i"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-j"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-k"
               multi_zone_ids = []
           },
       ]
   }
