本文介紹AHAS服務關聯角色AliyunServiceRoleForAHAS以及如何刪除該角色。

背景信息

AHAS服務關聯角色AliyunServiceRoleForAHAS是AHAS在某些情況下，為了完成自身的某個功能，需要獲取其他云服務的訪問權限而提供的RAM角色。更多關于服務關聯角色的信息請參見服務關聯角色。

應用場景

AHAS架構感知的資源拓撲、流量防護等功能需要訪問負載均衡SLB（Server Load Balancer）、專有網絡VPC（Virtual Private Cloud）、云服務器ECS（Elastic Compute Service）等云服務的資源時，可通過自動創建的AHAS服務關聯角色AliyunServiceRoleForAHAS獲取訪問權限。

權限說明

AHAS服務關聯角色AliyunServiceRoleForAHAS具備的云服務的訪問權限如下所示，更多權限說明請參見權限策略管理。

刪除AHAS服務關聯角色

如果您需要刪除AHAS服務關聯角色AliyunServiceRoleForAHAS，請注意刪除AliyunServiceRoleForAHAS后，會影響您AHAS數據的獲取。刪除AliyunServiceRoleForAHAS的操作步驟如下。

說明 如果當前賬號下還存在ACK集群，則需先刪除這些集群，才能刪除AliyunServiceRoleForAHAS，否則提示刪除失敗。
  1. 登錄RAM控制臺，在左側導航欄中單擊身份管理 > 角色。
  2. 在角色頁面的搜索框中，輸入AliyunServiceRoleForAHAS，自動搜索到名稱為AliyunServiceRoleForAHAS的RAM角色。
  3. 在右側操作列，單擊刪除。
  4. 在刪除角色對話框，單擊確定。
    重要 刪除服務關聯角色后會影響您AHAS數據的獲取，請謹慎刪除！

常見問題

問：為什么我的RAM用戶無法自動創建AHAS服務關聯角色AliyunServiceRoleForAHAS？

答：您需要擁有指定的權限才能自動創建或刪除AliyunServiceRoleForAHAS。因此，在RAM用戶無法自動創建AliyunServiceRoleForAHAS時，您需為其添加以下權限策略。
{
    "Statement": [
        {
            "Action": [
                "ram:CreateServiceLinkedRole"
            ],
            "Resource": "acs:ram:*:主賬號ID:role/*",
            "Effect": "Allow",
            "Condition": {
                "StringEquals": {
                    "ram:ServiceName": [
                        "ahas.aliyuncs.com"
                    ]
                }
            }
        }
    ],
    "Version": "1"
}
說明 請將主賬號ID替換為您實際的阿里云賬號（主賬號）ID。
