服务关联角色

背景信息

服务关联角色是指与某个云服务关联的RAM角色。在某些场景下，为了完成云服务的某个功能，需要获取其他云服务的访问权限。通过服务关联角色，您可以更好地创建云服务正常操作所需的权限，避免误操作带来的风险。更多信息，请参见服务关联角色。

创建服务关联角色

创建CC时，如果服务关联角色不存在，系统会自动创建一个名称为AliyunServiceRoleForCCIoT的服务关联角色，并且为该角色添加名称为AliyunServiceRolePolicyForCCIoT的权限策略，授予CC访问其他云资源的权限，策略内容如下。

删除服务关联角色

常见问题

为什么我的RAM用户无法自动创建CC服务关联角色（AliyunServiceRoleForCCIoT）？

您需要拥有指定的权限策略，才能自动创建或删除CC服务关联角色（AliyunServiceRoleForCCIoT）。因此，在RAM用户无法自动创建CC服务关联角色（AliyunServiceRoleForCCIoT）时，您需为其添加以下权限策略。

{
    "Statement": [
        {
            "Action": "ram:CreateServiceLinkedRole",
            "Resource": "*",
            "Effect": "Allow",
            "Condition": {
                "StringEquals": {
                    "ram:ServiceName": "cciot.aliyuncs.com"
                }
            }
        }
    ],
    "Version": "1"
}
