Python 部署到 Azure 应用服务失败且没有错误

Question

我有一个 Python 应用程序，可以通过 vscode 并使用 flask run 在本地运行，不会出现任何问题。

当我尝试以下命令将应用程序推送到 Azure 时，失败:

(.venv) C:\MOS>az webapp up --sku B1 --name mechanics-of-search-api --location "North Europe" -g "mechanics-of-search"
The webapp 'mechanics-of-search-api' doesn't exist

Please run the command az webapp log deployment show -n mechanics-of-search-api -g mechanics-of-search

当我尝试打开 https://mechanics-of-search-api.scm.azurewebsites.net/api/deployments/latest/log 处的日志时:

{"ClassName":"System.IO.FileNotFoundException","Message":"No log found for 'latest'.","Data":null,"InnerException":null,"HelpURL":null,"StackTraceString":"   at Kudu.Core.Deployment.DeploymentManager.GetLogEntries(String id) in /tmp/KuduLite/Kudu.Core/Deployment/DeploymentManager.cs:line 112\n   at Kudu.Services.Deployment.DeploymentController.GetLogEntry(String id) in /tmp/KuduLite/Kudu.Services/Deployment/DeploymentController.cs:line 432","RemoteStackTraceString":null,"RemoteStackIndex":0,"ExceptionMethod":null,"HResult":-2147024894,"Source":"Kudu.Core","WatsonBuckets":null,"FileNotFound_FileName":null,"FileNotFound_FusionLog":null}

如果我执行 az webapp logDeployment show -nmechanis-of-search-api -gmechanis-of-search

我不知道运行了什么或如何查找错误所在。我成功部署了 sample project 。该项目大约140MB。

一般来说，故障排除的第一步是使用应用服务诊断:

在 Web 应用的 Azure 门户上，从左侧菜单中选择诊断并解决问题。选择可用性和性能。检查应用程序日志、容器崩溃和容器问题选项中的信息，其中会出现最常见的问题。

其他注意事项

1. 确保您位于正确的文件夹中。 az webapp up 应该运行从包含您的代码的本地文件夹。最常见的错误正在父目录中运行命令。
2. 确认您的项目结构符合“自动下面的“运行时检测逻辑”部分。
3. 还有问题吗？创造我们的存储库中的一个问题: https://github.com/Azure/app-service-linux-docs/issues
