摘要(Abstract)

通过使用阿里云的RAM(Resource Access Management)服务,您可以将您云账号下RDS资源的访问及管理权限授予RAM中的子用户。 目前,可以在RAM中进行授权的资源类型只有dbinstance。在通过RAM进行授权时,资源的描述方式如下: 当子用户通过API访问RDS时,RDS后台会向RAM进行权限检查,以确保调用者拥有相应权限。每个API会根据涉及到的资源以及API的语义来确定需要检查哪些资源的权限。每个API的鉴权规则如下表所示: sts权限 加入收藏 上面章节只用到了 RAM 的子账号功能,这些子账号都是可以长期正常使用的,发生泄露后如果无法及时解除权限,会非常危险。 当开发者的 app 被用户使用之后,用户的数据要写入 ram-test-dev 这个实例。当 app 的用户数据很多时,要求能够安全地授权给众多的 app 用户上传数据,并且保证多个用户之间存储的隔离。 类似这种场景需要临时访问权限,应该使用 STS 来完成。STS 可以指定复杂的策略来对特定的用户进行限制,仅提供最小的权限。 创建角色 创建一个名为 ram_test_app 的子账号,不需要赋予任何权限,因为在扮演角色的时候会自动获得被扮演角色的所有权限。有关创建RAM用户更多详情,请参见使用示例中的步骤1至步骤7。 创建两个角色,RamTestAppReadOnly 和 RamTestAppWrite。一个用于读取等操作,一个用于上传文件的操作。 登录RAM 控制台。 选择角色管理 > 新建角色。 选择角色类型。这里选择用户角色。 填写类型信息。因为角色是被阿里云账号使用过的,因此选择默认的即可。然后单击下一步。 配置角色基本信息。本实例中角色名称填写 RamTestAppReadOnly,然后单击创建。 完成角色创建后,单击关闭。 创建完角色之后,角色是没有任何权限的,因此需要新建一个自定义的授权策略。 选择策略管理 > 新建授权策略。 选择空白模板。 填写授权策略名称。该示例中填写ram-test-app-readonly,策略内容填写如下:
