通过编写资源编排ROS添加加速域名 - CDN

使用资源编排服务ROS调用CDN。本文为您介绍如何编写一个资源编排的模板，自动化添加一个CDN的加速域名。

支持资源列表

资源编排服务ROS（Resource Orchestration Service）是阿里云提供的一项简化云计算资源管理的服务。开发者和管理员可以编写模板，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。更多详情，请参见什么是资源编排服务。

支持使用资源编排服务ROS调用CDN。编排的部分资源包括普通资源和数据资源。

普通资源：
- ALIYUN::CDN::Domain：用于添加加速域名。
- ALIYUN::CDN::DomainConfig：用于批量配置域名。
数据资源：
- DATASOURCE::CDN::Domains：用于查询已创建加速域名的基础信息

权限说明

在本案例中，需要添加一个加速域名。默认情况下资源编排直接使用当前登录控制台的用户凭证，要求当前用户必须具备以下权限：

AliyunCDNFullAccess: 管理CDN资源的权限。

阿里云账号拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维。请根据业务的实际情况按需分配权限后进行接口调用。RAM用户需具备操作CDN资源的权限。具体操作，请参见CDN系统权限策略参考。

操作步骤

登录资源编排ROS控制台，单击顶部导航栏地域下拉框，选择您需要的地域。
单击左侧菜单栏中的资源栈，选择创建资源栈 > 使用ROS。
- 指定模板：选中选择已有模板。
- 模板录入方式：选中输入模板。

模板内容选择ROS，并输入代码。

添加加速域名的语法、说明及示例，请参见ALIYUN::CDN::Domain。
