授权信息

访问控制(RAM)是阿里云提供的管理用户身份与资源访问权限的服务。使用RAM可以让您避免与其他用户共享阿里云账号密钥,并可按需为用户授予最小权限。RAM中使用权限策略描述授权的具体内容。
本文为您介绍块存储(ebs)为RAM权限策略定义的操作(Action)、资源(Resource)和条件(Condition)。块存储(ebs)的RAM代码(RamCode)为[{"popCode":"ebs","ramCodes":["ebs"]}],支持的授权粒度为RESOURCE

权限策略通用结构

权限策略支持JSON格式,其通用结构如下:
{
  "Version": "1",
  "Statement": [
    {
      "Effect": "<Effect>",
      "Action": "<Action>",
      "Resource": "<Resource>",
      "Condition": {
        "<Condition_operator>": {
          "<Condition_key>": [
            "<Condition_value>"
          ]
        }
      }
    }
  ]
}
各字段含义如下:
  • Effect:权限策略效果。取值:Allow(允许)、Deny(拒绝)。
  • Action:授予允许或拒绝权限的具体操作。具体信息,请参见操作(Action)
  • Resource:受操作影响的具体对象,您可以使用资源ARN来描述指定资源。具体信息,请参见资源(Resource)
  • Condition:指授权生效的条件。可选字段。具体信息,请参见条件(Condition)
    • Condition_operator:条件运算符,不同类型的条件对应不同的条件运算符。具体信息,请参见权限策略基本元素
    • Condition_key:条件关键字。
    • Condition_value:条件关键字对应的值。

操作(Action)

下表是块存储(ebs)定义的操作,这些操作可以在RAM权限策略语句的Action元素中使用,用来授予执行该操作的权限。下面对表中的具体项提供说明:
  • 操作:是指具体的权限点。
  • API:是指操作对应的API接口。
  • 访问级别:是指每个操作的访问级别,取值为写入(Write)、读取(Read)或列出(List)。
  • 资源类型:是指操作中支持授权的资源类型。具体说明如下:
    • 对于必选的资源类型,用背景高亮的方式表示。
    • 对于不支持资源级授权的操作,用全部资源表示。
  • 条件关键字:是指云产品自身定义的条件关键字。该列不体现适用于任何操作的通用条件关键字
  • 关联操作:是指成功执行操作所需要的其他权限。操作者必须同时具备关联操作的权限,操作才能成功。

资源(Resource)

下表是块存储(ebs)定义的资源,这些资源可以在RAM权限策略语句的Resource元素中使用,用来授予对该资源执行具体操作的权限。 其中,资源ARN是资源在阿里云上的唯一标识。具体说明如下:
  • {#}为变量标识,需要您替换为实际值。例如:{#ramcode}需要您替换为实际的云服务RAM代码。
  • *表示全部。例如:
    • {#resourceType}*时:表示全部资源。
    • {#regionId}*时:表示全部地域。
    • {#accountId}*时:表示全部阿里云账号。
