在 Azure ARM 部署模板中复制元素内的复制元素以创建资源的多个实例

Question

我正在尝试通过 copy element feature to create multiple instance of the same resource type (Microsoft.Web/sites/hostnameBindings 在我的 Azure ARM 部署模板中创建 "nested for loop"）

更具体地说，我正在尝试将多个主机名绑定到多个应用程序（Azure 应用程序服务网站）。

这可能吗？或者我需要走 linked templates 路径吗？

这是我到目前为止的尝试，但我无法让它发挥作用。

        { "appName": "app2", "hostNames": [ "app2.qqq.example.com" , "app2.ttt.example.com" ] },
        { "appName": "app3", "hostNames": [ "app3.qqq.example.com", "app3.ttt.example.com" ] }    
      ]
    }    
  }
}

      "copy": [
        {
          "name": "webAppCopy",
          "count": "[length(parameters('appList'))]"
        }        
      ],

    }
  ],
  "outputs": {}
}

Answer 1

我从未在文档中看到任何关于直接支持嵌套的内容循环。但是您可能可以使用 numeric functions 解决此问题，如下所示：

定义一个模板变量，它是应用程序数 * 每个应用程序的地址数。我们称这个变量为 bindingCount
使用 bindingCount 作为 "copy"
构造资源名称时，使用div和mod函数获取copyIndex并将其转回"app index"和"hostname"索引。我认为您必须在构造名称的公式中进行内联数学运算。

我最终采用了一种不同的方法来解决这个问题，这导致了稍微重复的名称，但给了我更好的灵活性和可读性
