分布式缓存服务 DCS

Organizations服务中的服务控制策略（Service Control Policy，以下简称SCP）可以使用以下授权项元素设置访问控制策略。

SCP不直接进行授权，只划定权限边界。将SCP绑定到组织单元或者成员账号时，并没有直接对组织单元或成员账号授予操作权限，而是规定了成员账号或组织单元包含的成员账号的授权范围。

本章节介绍组织服务中SCP使用的元素，这些元素包含了操作（Action）、资源（Resource）和条件（Condition）。

如何使用这些元素编辑SCP自定义策略，请参考创建SCP。

操作（Action）

操作（Action）即为SCP中支持的授权项。

  • “访问级别”列描述如何对操作进行分类（list、read和write等）。此分类可帮助您了解在SCP中相应操作对应的访问级别。
  • “资源类型”列指每个操作是否支持资源级权限。
    • 资源类型支持通配符号*表示所有。如果此列没有值（-），则必须在SCP语句的Resource元素中指定所有资源类型（“*”）。
    • 如果该列包含资源类型，则必须在具有该操作的语句中指定该资源的URN。
    • 资源类型列中必需资源在表中用星号（*）标识，表示使用此操作必须指定该资源类型。

    关于DCS定义的资源类型的详细信息请参见资源类型（Resource）。

  • “条件键”列包括了可以在SCP语句的Condition元素中支持指定的键值。
    • 如果该授权项资源类型列存在值，则表示条件键仅对列举的资源类型生效。
    • 如果该授权项资源类型列没有值（-），则表示条件键对整个授权项生效。
    • 如果此列条件键没有值（-），表示此操作不支持指定条件键。

    关于DCS定义的条件键的详细信息请参见条件（Condition）。

您可以在SCP语句的Action元素中指定以下DCS的相关操作。

资源类型（Resource）

资源类型（Resource）表示SCP所作用的资源。如表3中的某些操作指定了可以在该操作指定的资源类型，则必须在具有该操作的SCP语句中指定该资源的URN，SCP仅作用于此资源；如未指定，Resource默认为“*”，则SCP将应用到所有资源。您也可以在SCP中设置条件，从而指定资源类型。

DCS定义了以下可以在自定义SCP的Resource元素中使用的资源类型。

表3 DCS支持的资源类型

资源类型

URN

instance

dcs:<region>:<account-id>:instance:<instance-id>

migrationTask

dcs:<region>:<account-id>:migrationTask:<task-id>

条件（Condition）

条件（Condition）是SCP生效的特定条件，包括条件键和运算符。

  • 条件键表示SCP语句的Condition元素中的键值。根据适用范围，分为全局级条件键和服务级条件键。
    • 全局级条件键（前缀为g:）适用于所有操作，在鉴权过程中，云服务不需要提供用户身份信息，系统将自动获取并鉴权。 详情请参见：全局条件键。
    • 服务级条件键（前缀通常为服务缩写，如dcs:）仅适用于对应服务的操作，详情请参见表4。
    • 单值/多值表示API调用时请求中与条件关联的值数。单值条件键在API调用时的请求中最多包含一个值，多值条件键在API调用时请求可以包含多个值。例如：g:SourceVpce是单值条件键，表示仅允许通过某个VPC终端节点发起请求访问某资源，一个请求最多包含一个VPC终端节点ID值。g:TagKeys是多值条件键，表示请求中携带的所有标签的key组成的列表，当用户在调用API请求时传入标签可以传入多个值。
  • 运算符与条件键、条件值一起构成完整的条件判断语句，当请求信息满足该条件时，SCP才能生效。支持的运算符请参见：运算符。

DCS定义了以下可以在自定义SCP的Condition元素中使用的条件键，您可以使用这些条件键进一步细化SCP语句应用的条件。
