Azure YAML 部署失败并显示“错误：无法将 Web 包部署到应用服务。冲突（代码：409）”

Question

希望有人也看到了这一点。我们上一次成功构建是在 2019 年 12 月 6 日。新的部署尝试在部署步骤失败（构建和发布管道中存在相同问题）。

报错如下：

Got service connection details for Azure App Service:'OUR SITE'
Package deployment using ZIP Deploy initiated.
##[error]Failed to deploy web package to App Service.
##[error]Error: Error: Failed to deploy web package to App Service. Conflict (CODE: 409)
##[warning]Error: Failed to update deployment history. Error: Bad Request (CODE: 400)
App Service Application URL: OUR SITE

这是我们的部署YAML，抱歉这几天一直在做:(

# Node.js Express Web App to Linux on Azure

请注意：我曾尝试添加WEBSITE_WEBDEPLOY_USE_SCM = true到配置中，但这没有帮助。
上述构建没有任何更改，该构建YAML成功运行并提供给发布管道

谢谢你的帮助。

更新：使用 MS Dev-Ops 引发的票证您可以system.debug: true在变量部分中添加以获得更详细的日志记录。
这让我看到AppService返回409代码，因为它认为部署已经在进行中。如果我得到解决方案，我将编辑这篇文章。

这是调试信息：

票在这里：409 无法部署 web 包

Answer 1

重新启动应用服务解决了我的问题。

我的应用服务计划已经是付费订阅，容量没有问题。我刚刚重新启动了应用服务，一切正常。

Answer 2

因此，在与 MS 支持人员进行大量讨论后，这是票证

事实证明，真正的问题是我的应用程序服务计划已满。在开发过程中，我们使用免费服务，但存在限制。我们已经达到了这个限制，这个消息确实是转移注意力，根本不是真正的问题。

不管怎样，我升级到了第一层付费订阅，现在一切正常。

Answer 3

目前（2020 年 7 月/8 月），该问题实际上是 Microsoft 对支持某些区域的应用程序服务的虚拟机的更新，如本 github 问题所述：https ://github.com/projectkudu/kudu/issues/3042

解决方法（在此回复中列出：https://github.com/projectkudu/kudu/issues/3042#issuecomment-665997217）似乎有帮助。任何一个

1. 通过 SCM 门户重新启动 Kudu（通过 Process Explorer 选项卡终止 w3wp 进程）
2. 重新启动应用程序服务（导致停机）
3. 扩大和缩小您的服务（尽管有些人报告他们必须在其间进行部署）
