Json 使用Azure Devops部署Azure策略ARM模板失败

我们已经为“允许的位置”构建了一个Azure策略。创建所需的template.json和parameter.json，如下所示： Template.json

在将json文件上载到Azure repos后尝试使用Azure管道运行时，出现以下错误

[错误]请求内容无效，无法反序列化：“在JSON中找不到必需属性”resources“。路径“properties.template”，第1行，位置222“。 尽管在template.json中提到了资源，但由于此错误，它失败了。任何人都能给出任何见解

   {
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
   "contentVersion": "1.0.0.0",
  "parameters": {
      "listOfAllowedLocations": {
  "type": "array"
    }
  },
  "variables": {},
  "resources": [
   {
  "type": "Microsoft.Authorization/policyDefinitions",
  "name": "policylocation",
  "apiVersion": "2018-03-01",
  "properties": {
    "policyType": "Custom",
    "displayName": "policylocation",
    "description": "",
    "mode": "all",
    "parameters": {
      "listOfAllowedLocations": {
        "type": "array",
        "metadata": {
          "description": "The list of locations that can be specified when deploying resources.",
          "displayName": "Allowed locations"
        }
      }
    },
"policyRule": {
  "if": {
    "allOf": [
      {
        "field": "location",
        "notIn": "EastUS"
      },
      {
        "field": "location",
        "notEquals": "global"
      },
      {
        "field": "type",
        "notEquals": "Microsoft.Compute/virtualMachines"
      }
    ]
  },
  "then": {
    "effect": "deny"
  }
}
  }
}
  ]
}

Parameter.json

   {
 "$schema": "https://schema.management.azure.com/schemas/2015-01- 
  01/deploymentParameters.json#",
 "contentVersion": "1.0.0.0",
 "parameters": {
"listOfAllowedLocations": {
  "type":"array",
  "value": "EastUS"
   }
   }
 }

问题是策略没有利用listOfAllowedLocations参数。我将删除它，并使参数仅为空brakets

---

以下是一些原因：

当我尝试使用给定的模板和参数文件部署策略时，我收到以下错误

{
    "error": {
        "code": "InvalidDeploymentParameterType",
        "message": "The type of deployment parameter 'listOfAllowedLocations' should not be specified. Please see https://aka.ms/resource-manager-parameter-files for details."
    }
}

这意味着您有一个未使用的参数（listOfAllowedLocations）。虽然对于大多数语言模式来说，有一个未使用的参数是可以的，但对于策略来说则不是。首先删除此参数或将此参数添加到策略中以便使用

接下来，根据您收到的误导性错误消息，我对您的部署方法感到好奇。策略可以以多种不同的方式部署。门户、Powershell、RESTAPI等等。我更喜欢RESTAPI方法，因为它在定义和使用方面提供了相当大的灵活性和简单性。如果您选择RESTAPI，实际上您可以分别选择两种不同的方法（作为Azure部署或策略定义），它们是以下端点

PUT https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.Resources/deployments/{deploymentName}?api-version=2019-10-01

我更喜欢部署路由，因为它使用azure部署机制来部署策略，该策略提供了一致且用户友好的故障排除、重试和检查方法。它还允许您将策略部署为模板文件和参数文件，在部署中嵌套部署（这在更复杂的用例中非常有用），并在部署范围和策略范围中指定参数。但是，部署也有一些限制，例如每个订阅和资源组配额（目前为800）。定期打扫一下房子会有帮助的

使用Azure部署REST API方法，我鼓励您尝试以下操作之一，具体取决于您的意图

选项1a：您希望保留“listOfAllowedLocations”作为参数，并在策略中使用它。您还希望在部署范围应用该参数，以便生成的部署策略具有静态定义的允许位置列表

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/Microsoft.Resources/deployments/{deploymentName}?api-version=2019-10-01

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/Microsoft.Resources/deployments/{deploymentName}?api-version=2019-10-01

正文：

选项1b：您希望保留“listOfAllowedLocations”作为参数，并在策略中使用它。您还希望在策略定义范围中应用该参数，以便在分配时可以操作生成的已部署允许位置列表。请注意，在策略资源定义（“[]”）中，参数的作用域和参数的转义存在细微差异

正文：

选项2：允许位置的静态定义。这将基本上避免通过部署或策略分配传递参数的过程

我们修复了使用powershell而不是通过devops部署策略的问题。我们的ARM模板与您在上面提供的模板匹配。感谢您的帮助谢谢！如果这解决了问题，请不要忘记向上投票。如果您有任何问题，请在向下投票前留下评论。谢谢！
