Question

我有一个部署到我的 Azure Web 应用程序的管道，但大多数情况下会出错，因为它无法部署到我的 Web 应用程序。任务大约需要 25 分钟：

...
Copying file: 'frontend/.gitignore'
Copying file: 'frontend/README.md'
Copying file: 'frontend/package.json'
Copying file: 'frontend/tsconfig.json'
Copying file: 'frontend/yarn.lock'
Omitting next output lines...
An error has occurred during web site deployment.
Kudu Sync failed
\n/opt/Kudu/Scripts/starter.sh "/home/site/deployments/tools/deploy.sh"
##[error]Failed to deploy web package to App Service.
##[error]To debug further please check Kudu stack trace URL : https://$someapp:***@someapp.scm.azurewebsites.net/api/vfs/LogFiles/kudu/trace
##[error]Error: Package deployment using ZIP Deploy failed. Refer logs for more details.
...

当我启用：system.debug = true 时，在开始复制工件文件之前，我看到这些日志重复了很多次：

此任务仅在 myweb 应用程序中的特定插槽失败，作者插槽和生产插槽工作正常，工作大约需要 6 分钟

有什么想法可能出问题了吗？

Answer 1

根据执行 here 的讨论和故障排除，我尝试在 Standard S1 定价层上设置 Linux 应用服务，启用 5（最大）插槽，并通过 Azure Pipelines 配置 CI/CD .不幸的是，尽管进行了多次不同的试验，我还是无法重现与您相同的错误。

我建议您尝试以下操作：

Kudu Sync failed 类似于大约一年前的未解决问题：ZipDelpoy on azure web app linux fails during kudu sync #2972。请检查 kudu 上 https://<appname>.scm.azurewebsites.net/api/vfs/LogFiles/kudu/trace 或 /deployment 或 Kudu 的 DebugConsole (/LogFiles/kudu/\*) 上的跟踪/部署日志文件，并检查这是否是由部署锁定失败引起的。在这种情况下，请检查 this wiki 以在部署期间处理锁定的文件。
尝试不同的部署方法，例如 run from package（以避免资源锁定）、使用 FTP/S 或 local git deployment。这应该可以帮助您进一步缩小问题的范围，无论是由应用服务/部署方法引起的，还是由 ADO 管道/任务引起的。
扩展到下一个更高层并重新触发您的管道。如果成功，您可以缩减到原始层。这也会间接重启您的 SCM 站点。

如果上述解决方法没有帮助，您可以检查以下内容：

使用 TakeAppOfflineFlag、DeploymentType 或 RenameFilesFlag 等选项自定义部署任务以简化部署。
尝试在部署前重新启动应用/插槽以回收应用池。
检查您的应用是否正在运行到您的层级的任何 prescribed limits（例如：文件系统存储）。
深入了解您的应用的 available metrics 以识别任何 CPU/内存异常。
尝试使用 Diagnose and solve problems 工具获取有关您的应用的任何其他见解。
如果您的环境允许，请尝试设置并部署到您的应用服务中的新槽，或尝试验证这是否发生在不同区域的另一个应用中。
