Nginx + Django：ModuleNotFoundError：没有名为“app”的模块

Question

我正在尝试使用 Docker 中的 Nginx 和 Gunicorn 运行我的 Django 应用程序

在 docker 撰写日志中，我有以下错误：（完整日志： https://pastebin.com/EXd3Bsii ）

File "/usr/local/lib/python3.9/site-packages/gunicorn/util.py", line 359, in import_app
django_1  |     mod = importlib.import_module(module)
django_1  |   File "/usr/local/lib/python3.9/importlib/__init__.py", line 127, in import_module
django_1  |     return _bootstrap._gcd_import(name[level:], package, level)
django_1  |   File "<frozen importlib._bootstrap>", line 1030, in _gcd_import
...
django_1  |   File "<frozen importlib._bootstrap>", line 984, in _find_and_load_unlocked
django_1  | ModuleNotFoundError: No module named 'app'

我该如何解决这个问题？

我应该指定 wsgi 配置吗？

我的代码wsgi,py

import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'potok.settings')
application = get_wsgi_application()

nginx-conf.conf

upstream app {
    server django:8000;
}

server {
    listen:80;
    server_name: localhost;

    location / {
        proxy_pass http://app;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect_off;
    }

    location /staticfiles/ {
        alias /var/www/html/staticfiles/;
    }
}

你的nginx.conf有问题： proxy_pass http://django:8000;

upstream app {
    server django:8000;
}

server {
    listen:80;
    server_name: localhost;

    location / {
        proxy_pass http://django:8000;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect_off;
    }

    location /staticfiles/ {
        alias /var/www/html/staticfiles/;
    }
}

Nginx and django are in the same network, nginx can access the django instances generated by gunicorn using the name of the container and the port guniconr binds the workers to.

您还需要修改 docker-compose.yaml。 Gunicorn 无法访问应用程序，因为您将其命名为application而不是应用程序。

version: '3.9'

services:
  django:
    build: . # path to Dockerfile
    command: sh -c "gunicorn --bind 0.0.0.0:8000 wsgi:application"
    volumes:
      - .:/project
      - static_data:/project/static
    expose:
      - 8000
