資源編排ROS支持在模板中定義所需的阿里云資源（例如ECS實例、RDS數據庫實例）、資源間的依賴關系等。ROS的編排引擎將根據模板自動完成所有資源的創建和配置，實現自動化部署及運維。本文介紹如何通過OSS以及ROS服務快速創建Nginx。
前提條件
步驟一：在Bucket中上傳Nginx安裝包
步驟二：通過ROS新建資源棧
選擇模板。
登錄資源編排控制臺。
在左側導航欄，單擊資源棧。
在頁面左上角的地域下拉列表，選擇華東1（杭州）。
在資源棧列表頁面，單擊創建資源棧，然后在下拉列表中選擇使用ROS。
在選擇模板頁面，指定模板為選擇已有模板，模板錄入方式選擇輸入模板，在ROS模板內容的JSON頁簽輸入以下模板內容，然后單擊下一步。
