如何通過 ARM 模板在單個 azure 資源上添加多個 RBAC 角色

Question

我正在嘗試為單個資源中的用戶/組創建多個 RBAC 角色。我可以將單個組或用戶添加到資源中，但無法提供多個用戶（一個具有所有者權限，另一個組/用戶具有貢獻者權限）在同一資源上。 我開始知道“名稱”應該不同，但是當我提供不同的名稱時，它會顯示“無法找到資源。

我已將 principalid 和 rolegroup 聲明為 arrays。 我正在嘗試創建 Azure 分析服務。 下面是代碼。 我通過運行以下代碼得到的錯誤是“部署模板驗證失敗： '資源 Microsoft.AnalysisServices/servers/aascmigqa/providers/Microsoft.Authorization/roleAssignments/40ba7757-1e75-5eb7-b6ca-ea5a9ca77ce3'在第 1 行' 和列 '2237' 在模板中定義了多次。有關使用詳細信息，請參閱https://aka.ms/arm-template/#resources 。'。

這是語法錯誤還是不可能的事情。
提前致謝！

您需要為每個作業生成唯一的名稱 \ guid，您可以這樣做：

guid(uniqueString(variables('server_name'), copyIndex()))

這將確保每個資源都有自己的 guid
