通過編寫Resource Orchestration Service添加加速網域名稱 - CDN

使用Resource Orchestration Service服務ROS調用CDN。本文為您介紹如何編寫一個Resource Orchestration Service的模板，自動化添加一個CDN的加速網域名稱。

支援資源清單

Resource Orchestration Service服務ROS（Resource Orchestration Service）是阿里雲提供的一項簡化雲端運算資源管理的服務。開發人員和管理員可以編寫模板，在模板中定義所需的阿里雲資源（例如：ECS 執行個體、RDS 資料庫執行個體）、資源間的依賴關係等。ROS 的編排引擎將根據模板自動完成所有資源的建立和配置，實現自動化部署及營運。更多詳情，請參見什麼是Resource Orchestration Service服務。

支援使用Resource Orchestration Service服務ROS調用CDN。編排的部分資源套件括普通資源和資料資源。

普通資源：
- ALIYUN::CDN::Domain：用於添加加速網域名稱。
- ALIYUN::CDN::DomainConfig：用於大量設定網域名稱。
資料資源：
- DATASOURCE::CDN::Domains：用於查詢已建立加速網域名稱的基礎資訊

許可權說明

在本案例中，需要添加一個加速網域名稱。預設情況下Resource Orchestration Service直接使用當前登入控制台的使用者憑證，要求目前使用者必須具備以下許可權：

AliyunCDNFullAccess: 管理CDN資源的許可權。

阿里雲帳號擁有所有API的存取權限，風險很高。強烈建議您建立並使用RAM使用者進行API訪問或日常營運。請根據業務的實際情況按需分配許可權後進行介面調用。RAM使用者需具備操作CDN資源的許可權。具體操作，請參見CDN系統權限原則參考。

操作步驟

登入Resource Orchestration Service控制台，單擊頂部導覽列地區下拉框，選擇您需要的地區。
單擊左側功能表列中的資源棧，選擇建立資源棧 > 使用ROS。
- 指定模板：選中選擇已有模板。
- 模板錄入方式：選中輸入模板。

模板內容選擇ROS，並輸入代碼。

添加加速網域名稱的文法、說明及樣本，請參見ALIYUN::CDN::Domain。
