阿里云权限管理机制包括访问控制（简称RAM）和安全凭证管理（简称STS），灵活使用RAM和STS，可以极大地提高管理的灵活性和安全性。本文介绍如何在不同的场景下配置仓库的访问控制。

背景信息

默认情况下，主帐号对自己的资源拥有完整的操作权限。借助RAM和STS，可以使不同的子账号拥有访问镜像资源的不同权限，同时也支持为用户提供临时的访问授权。在了解如何配置授权策略前，请先详细阅读RAM产品文档。

系统策略配置

  • AliyunContainerRegistryFullAccess

    子用户拥有该授权后，对于镜像资源的权限等同于主账号，可以做任意操作。

    {
  "Statement": [
    {
      "Action": "cr:*",
      "Effect": "Allow",
      "Resource": "*"
    }
  ],
  "Version": "1"
}
  • AliyunContainerRegistryReadOnlyAccess

    子用户拥有该授权后，对于所有镜像资源有只读权限，例如：可以查看仓库列表，Pull镜像等。

    {
  "Statement": [
    {
      "Action": [
        "cr:Get*",
        "cr:List*",
        "cr:Pull*"
      ],
      "Effect": "Allow",
      "Resource": "*"
    }
  ],
  "Version": "1"
}

典型场景策略配置

若用户子账号需要调用容器镜像服务开放的 OpenAPI，需要参照镜像服务鉴权规则授予子账号相应的操作权限；若用户子账号需要使用容器镜像服务控制台，建议为子账号配置额外的权限策略： 

{
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "cr:ListInstance*",
                "cr:GetInstance*"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cr:GetInstance*",
                "cr:ListInstance*"
            ],
            "Resource": "acs:cr:$regionid:$accountid:instance/$instanceid"
        }
    ],
    "Version": "1"
}

RAM说明

在使用RAM对子账号授权时，请特别关注下面的说明，以免您为子账号授予过大的权限。

如果您通过RAM为某一个子账号授予阿里云所有资源的管理权限（即AdministratorAccess），无论您之前是否为该子账号授予过镜像服务的权限，该子账号都将拥有对镜像服务的全部权限。

镜像服务鉴权规则

  • 资源描述

    在通过RAM进行授权时，资源的描述方式如下表所示：

    资源类型 授权策略中的资源描述
    * acs:cr:$regionid:$accountid:*
    instance acs:cr:$regionid:$accountid:instance/$instanceid
    repository

    acs:cr:$regionid:$accountid:repository/$instanceid/*

    acs:cr:$regionid:$accountid:repository/$instanceid/$namespacename/*

    acs:cr:$regionid:$accountid:repository/$instanceid/$namespacename/$repositoryname

    acs:cr:$regionid:$accountid:repository/$instanceid/$namespacename
    chart

    acs:cr:$regionid:$accountid:chart/$instanceid/*

    acs:cr:$regionid:$accountid:chart/$instanceid/$chartnamespacename/*

    acs:cr:$regionid:$accountid:chart/$instanceid/$chartnamespacename

    acs:cr:$regionid:$accountid:chart/$instanceid/$chartnamespacename/<br>$chartrepositoryname

    参数说明，如下表所示：

    参数名称 说明
    $regionid 地域 ID，可用*代替。
    $accountid 云账号数字 ID，可用 * 代替。
    $instanceid 容器镜像服务企业版实例 ID
    $namespacename 命名空间名称。
    $repositoryname 镜像仓库名称。
    $chartnamespacename Chart 镜像命名空间名称。
    $chartrepositoryname Chart 镜像仓库名称。
  • 鉴权规则

    子账号或者STS方式访问镜像服务API时，镜像服务会向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：

    API 鉴权Action 鉴权Resource
    GetAuthorizationToken cr:GetAuthorizationToken *
    GetChartNamespace cr:GetNamespace acs:cr:$regionid:$accountid:chart/$instanceid/$chartnamespacename
