ARM 模板应用服务配置 - 竞争条件/不一致的行为答案

【问题标题】：ARM Template App Service Config - Race Condition / Inconsistent BehaviorARM 模板应用服务配置 - 竞争条件/不一致的行为
【发布时间】：2018-10-26 17:04:52
【问题描述】：

使用下面的 ARM 模板，我们 enabled diagnostic settings for our app service 以及在 resources 元素下定义 appSettings 配置。问题是在从模板部署我们的应用服务后间歇性地 - appSettings 没有被分配，但诊断设置是。

如果有更好的方法为logs 和appSettings 定义配置以提供更一致的站点输出的应用服务，有人可以指导我们吗？我们每天为 PR 构建和拆除数十个应用程序服务，因此这一点非常明显。

appSetting WEBSITE_LOAD_USER_PROFILE 将在创建应用服务时随机删除。我们是缺少dependsOn 还是需要升级apiVersion？

【解决方案1】：

您应该将应用设置与functionApp Resource 一起配置，而不是在单独的资源中定义设置。我已经使用它并定义了各种应用程序设置，它工作正常。试试下面的例子。

{
      "apiVersion": "[variables('sitesApiVersion')]",
      "type": "Microsoft.Web/sites",
      "kind": "functionapp",
      "location": "[resourceGroup().location]",
      "name": "[parameters('functionAppName')]",
      "scale": null,
      "properties": {
        "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', parameters('functionApp_appServicePlanName'))]",
        "siteConfig": {
          "appSettings": [
            {
              "name": "WEBSITE_LOAD_USER_PROFILE",
              "value": "1"
            }
           ]
        },
        "dependsOn": [
          "[resourceId('Microsoft.Web/serverfarms', parameters('functionApp_appServicePlanName'))]",
          "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"
        ]
      }
    }
