Question

我正在尝试使用https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-multiple#serial-copy

中提到的带有复制选项的嵌套资源

我在嵌套资源变量块中定义了“lbApiVersion”，但是有些嵌套变量块无法识别。

下面是我正在尝试的ARM模板，这只是实际场景中的示例我想将数组传递给arm模板然后在循环中创建多组资源，所以在这种情况下我需要嵌套变量块。

错误 - “消息”：“无法处理资源的模板语言表达式”/subscriptions/*************/resourceGroups/cluv2/providers/Microsoft.Resources/deployments/loop-在'14'行和'10'列'0'。'模板找不到变量'lbApiVersion'。

Answer 1

根据我的经验，当您内联定义嵌套模板时（在现有模板的代码中），他们从父模板中获取参数和变量值，因此只需将变量定义移动到父模板

Answer 2

不幸的是，您无法在嵌套模板中将变量和参数用作indicated by the documentation。您可以在外部模板中使用它们。

如果要在嵌入式模板中部署多个资源，请在主模板中声明对象类型的变量或参数，如下所示：

"variables" : {
    "loadBalancers": [
      {
        "version": "2015-06-15"
      },
      {
        "version": "2015-06-15"
      }
    ]
}

您在Microsoft.Resources / deployments资源上的副本将如下所示：

  "copy": {
    "name": "loadBalancerLoop",
    "count": "[length(variables('loadBalancers'))]"
  }

然后，在您的嵌套资源中，使用copyIndex（）来获取版本

"apiVersion": "[variables('loadBalancers')[copyIndex()].version]"
