Azure 部署失败：Django Azure Web 应用程序

Question

我正在运行 Django Web 应用程序 - 它在本地运行，并且已成功部署到 Azure。

我现在在日志流上看到以下错误：

这是我的启动命令：

gunicorn --bind=0.0.0.0 --timeout 600 trplbackend.wsgi:application

我的项目结构经检查似乎是正确的。在本地运行此命令也有效。

我检查了 docker 日志并尝试重新部署，但似乎没有任何效果。就上下文而言，过去我的 Azure Web App 部署也很不稳定。只需通过 Azure Pipelines 重新部署而不进行任何更改似乎就有效。

关于如何调查或修复此错误并使部署更加稳健有什么想法吗？

谢谢你。

Answer 1

我尝试将 Django 应用程序部署到 azure 应用程序服务，没有任何问题。

为了避免您遇到的错误消息：

确保在部署期间正确配置并激活安装 Django 项目依赖项的虚拟环境。
确保
```
trplbackend
```
模块存在于您的项目结构中并且可以访问。错误的路径或错误配置的模块名称可能会引起问题。

这是我的项目结构：

project_root/
├── myapp/        
├── trplbackend/   
├── venv/          
├── manage.py      
├── Procfile       
└── requirements.txt

过程文件：

web: gunicorn --bind=0.0.0.0 trplbackend.wsgi:application

设置.py：

BASE_DIR = Path(__file__).resolve().parent.parent
SECRET_KEY = 'your secretkey'
