azure - ARM 模板应用程序服务配置 - 竞争条件/行为不一致

Question

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，从模板部署我们的应用程序服务后，间歇性地不会分配 appSettings，但会分配诊断设置。

如果有更好的方法来定义应用服务的 logs 和 appSettings 的配置，以提供更一致的站点输出，有人可以指导我们吗？我们每天为 PR 构建构建和拆卸数十个应用程序服务，因此这一点非常明显。

创建应用服务时，appSetting WEBSITE_LOAD_USER_PROFILE 将被随机删除。我们是否缺少 dependsOn 还是需要升级 apiVersion？

您应该将应用设置与 functionApp 资源 一起配置，而不是在单独的资源中定义设置。我已经使用了它并定义了各种应用程序设置，并且运行良好。请尝试像下面的示例一样。

{
      "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'))]"
        ]
      }
    }
