How can I configure Django, Nginx, and Docker to serve media files in production with DEBUG off?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm running a Django DRF backend with a Svelte frontend, using Nginx as a proxy and Docker for containerization. All static files (like admin styles) are served correctly, but images in the MEDIA folder aren't loading when DEBUG is set to False. I've added the URL configuration for media files in urls.py and defined MEDIA settings in settings.py. My current Nginx, docker-compose, and Dockerfile configurations are below. If someone could point me in the right direction, it would be much appreciated!

urls.py

PYTHON
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

settings.py:

PYTHON
LOCALE_PATHS = (os.path.join(BASE_DIR, "locale"),)
STATIC_URL = "/static/"
STATIC_ROOT = os.path.join(BASE_DIR, "static")

MEDIA_URL = "/media/"
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

nginx.conf

NGINX
worker_processes 1;

events {
  worker_connections 1024;
}

http {
    upstream backend {
        server back:7000;
    }

     server {
        listen 80;

        location /api {
            proxy_pass http://backend;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_redirect off;
        }

        location /sitemap.xml {
            proxy_pass http://front:8080/sitemap.xml;
            # proxy_pass http://front:3000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }

        location / {
            proxy_pass http://front:8080;
            # proxy_pass http://front:3000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }

        location /admin {
            proxy_pass http://backend;  
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_redirect off;
        }

        location /static/ {
            alias /back/static/;
        }

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

Fixing Media Files Not Loading in Django with Nginx and Docker

The issue with your media files not loading when DEBUG is set to False is likely due to how Nginx is configured to handle media files. Here are the key problems and solutions:

Main Issues

Your Nginx configuration is trying to proxy media requests to Django instead of serving them directly
The media directory isn't properly mounted as a volume in your Docker setup
When DEBUG is False, Django doesn't serve media files by default

Solution

1. Update Nginx Configuration

Change your media location block in nginx.conf to serve files directly instead of proxying:

NGINX
location /media/ {
    alias /back/media/;  # Point to the actual media directory
}

This is similar to how you're handling static files, which is working correctly.

2. Update Docker Compose

You need to ensure the media directory is properly mounted as a volume. Add it to your back service:

YAML
services:
  back:
    # existing configuration...
    volumes:
      - ./back:/back
      - ./back/media:/back/media  # Explicitly mount media directory
    # rest of configuration...

  nginx:
    # existing configuration...
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./back/media:/back/media  # Mount media directory in nginx container
    # rest of configuration...

3. Ensure Media Directory Exists

Make sure the media directory exists in your project structure:

BASH
mkdir -p ./back/media

4. Additional Considerations

Make sure your media files have proper permissions
If you're uploading files through Django, ensure the upload path is correctly set
You might need to add a volume for media in your Dockerfile or ensure it's created during build

Complete Nginx Media Configuration

For completeness, here's how your media location block should look:

NGINX
location /media/ {
    alias /back/media/;
    expires 30d;  # Optional: Add caching for media files
    add_header Cache-Control "public, max-age=2592000";  # Optional
}

This approach will serve your media files directly through Nginx rather than proxying the requests to Django, which is more efficient and works when DEBUG is False.
