Question

如果数组参数中有4个以上的条目，则需要部署特定的资源。我能够使用5个（或更多）条目来执行此操作，但是我还需要部署不因3个或更少的条目而失败，而根本不要创建该资源。现在，我收到3个或更少条目的以下错误：

错误：代码= InvalidTemplate； Message =部署模板验证失败：“第56行”和“ 19”列的“模板”副本定义的副本数无效。复制计数必须为正整数值，并且不能超过“ 800”。请参阅https://aka.ms/arm-copy 使用情况的详细信息。'。

我尝试为资源添加条件：

...
  "resources": [
    {
      "condition": "[greater(length(parameters('apps')),4)]",
      "name": "[concat(parameters('apps')[copyIndex(4)].name,'-webtest')]",
...

甚至：

...
  "resources": [
    {
      "condition": false,
      "name": "[concat(parameters('apps')[copyIndex(4)].name,'-webtest')]",
...

，但仍然出现相同的错误。这是模板：

Answer 1

尝试这样做：

"condition": "[greater(length(parameters('apps')),4)]",

并设置您要复制到的位置：

"copy": {
  "name": "createWebTests",
  "count": "[if(greater(length(parameters('apps')),4), sub(length(parameters('apps')),4), 1)]"
}

这应该可以解决以下情况：在您的情况下，计数为负，并且当阵列中的项目少于4个时仍不部署任何东西
