我正在尝试将 Django 项目移植到 Docker-Compose 以进行部署。
我在网上学习了各种教程，据我了解，我的应用程序所需的唯一服务是 Django 和 Postgres。这是我的 docker-compose.yml 文件:
db:
image: postgres:latest
ports:
- "5432"
environment:
POSTGRES_PASSWORD: postgres
POSTGRES_USER: postgres
web:
build: .
ports:
- "8000:8000"
volumes:
- .:/code
links:
- db
command: python3 manage.py runserver 0.0.0.0:8000
我已经在我的 virtualenv 中本地测试了 python 命令并且服务器启动了，但是，当我在应用程序副本所在的文件夹中运行“docker-compose up”时，我得到以下输出:

没有关于服务器启动或类似内容的消息，我知道由于有关弃用的警告消息，它正在编译我的代码，但我在这里很困惑。谁能看到我的错误吗？
更新:
经过仔细检查并更改 DJango 服务器的端口，我发现访问网页会返回“加载页面时与服务器的连接已重置”错误。这表明该页面上正在设置某些内容。但我仍然无法访问它。我知道 Docker-Compose 正在像教程中的简单 Django 应用程序一样工作得很好。
最佳答案
您是否EXPOSE django 容器的端口？
关于python - Django 服务器不会在 Docker-Compose 中启动，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33570701/
