资源编排ROS支持在模板中定义所需的阿里云资源(例如ECS实例、RDS数据库实例)、资源间的依赖关系等。ROS的编排引擎将根据模板自动完成所有资源的创建和配置,实现自动化部署及运维。本文介绍如何通过OSS以及ROS服务快速创建Nginx。
前提条件
步骤一:在Bucket中上传Nginx安装包
步骤二:通过ROS新建资源栈
选择模板。
登录资源编排控制台。
在左侧导航栏,单击资源栈。
在页面左上角的地域下拉列表,选择华东1(杭州)。
在资源栈列表页面,单击创建资源栈,然后在下拉列表中选择使用ROS。
在选择模板页面,指定模板为选择已有模板,模板录入方式选择输入模板,在ROS模板内容的JSON页签输入以下模板内容,然后单击下一步。
