从Visual Studio和App服务进行Web部署出了什么问题？

Question

突然,Web部署开始失败.

Could not find file 'D:\home\site\wwwroot\App_Offline.htm'.

我停止了服务,但部署仍然失败.

当我尝试从Kudu PowerShell UI中的wwwroot删除任何文件时,我收到错误"404 file not find",但刷新后仍然显示该文件.当我试图直接在powershell中删除文件时,我收到错误

Cannot remove item D:\home\site\wwwroot\Azure.Storage.dll: Invalid access to memory location.
At line:1 char:1
+ del .\Azure.Storage.dll
+ ~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : WriteError: (D:\home\site\wwwroot\Azure.Storage. 
   dll:FileInfo) [Remove-Item], IOException
    + FullyQualifiedErrorId : RemoveFileSystemItemIOError,Microsoft.PowerShell 
   .Commands.RemoveItemCommand

我删除了该服务,重新创建它,并且Visual Studio中的第一个部署是Ok.但第二天部署再次失败.这些部署之间唯一的事情就是从VSTS部署.但我之前能够以任何顺序从VSTS和Visual Studio部署而没有任何问题.

我是该应用服务的所有者.

Answer 1

突然之间,VSTS默认部署模式变为Run-From-Zip.

解决方案是在VSTS部署中设置" 选择部署方法"复选框,并确保选中" Web部署".

要"解锁"服务,您需要从应用程序设置页面删除设置WEBSITE_RUN_FROM_ZIP

Answer 2

我今天在Net Core 2.2上遇到了同样的问题，解决方案是删除天蓝色的appsettings中的设置“ WEBSITE_RUN_FROM_PACKAGE”

Answer 3

我们也遇到了同样的问题-文件系统在变为只读WEBSITE_RUN_FROM_PACKAGE=1。在最近的平台升级期间，Azure应用服务似乎正在自动添加此应用设置。

我确实建议通过Web部署使用“从程序包运行”-但您可以通过设置轻松还原其强制更新WEBSITE_RUN_FROM_PACKAGE=0。如果您使用的是Azure DevOps，则最新版本的App Service Deploy v4支持Run-From-Package。

Answer 4

这是因为Azure DevOps (VSTS) Pipeline 中的AzureWebApp任务将“WEBSITE_RUN_FROM_PACKAGE”更新为“1”。这主要由 Azure Functions 使用，我们需要在其中部署整个包（并将 wwwroot 设为只读）。虽然它在 Functions 中非常有用，但您会在普通 Web 应用程序中看到奇怪的东西（例如找不到 App_Offline、找不到 wwwroot/lib 文件夹、您会在 FTP 文件夹中看到旧文件但在 Kudu 控制台中看到最新文件等）。

最简单的解决方法是将 YAML 文件中的设置“deploymentMethod”更新为“zipDeploy”。

Answer 5

转到配置 -> azure 门户中的应用程序设置，将“ WEBSITE_RUN_FROM_PACKAGE ”的值从“1”更改为“0”。然后再次发布。

这解决了我的问题。
