Docker – Static Files not being served by NGINX, instead it passes the request to Django app

I have created a django app and running it using docker and docker compose, but the static files are not getting served by nginx, instead the request get passed to django server. Please help, I was trying docker compose for first time🥲

}

server {
    listen 80;

    location /static/ {
        alias /app/static/;
    }

    location /media/ {
        alias /app/media/;
    }

    location / {
        proxy_pass http://django_server;
    }
}
  • settings.py
...

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

...

Observations

  • all containers started successfully
  • upon visiting to localhost i saw the django app but without static files
  • by checking logs i came to see that /static/..... requests were passed on to django instead of being served by nginx
  • i checked that volumes are mounted correctly between django and nginx, I also cross checked by creating a file from django’s interactive shell in static folder and it was visible in nginx’s /app/static folder and vice versa
  • django logs

    I found the solution, By including proxy headers in nginx conf file, requests were handled correctly.

    upstream django_server {
    server django:8000;
}

server {
    listen 80;

    location /static/ {
        alias /app/static/;
    }

    location /media/ {
        alias /app/media/;
    }

    location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_pass http://django_server;
    }
}

    So I’m not sure but maybe instead of alias you could use root and rewrite the request on NGINX. It can be like:

    location /static{
    rewrite /static/(.*) /static/$1 break;
    root /path/to/project;
}

    First try without the rewrite, just setting the root for the static files, if it doesn’t work try to set the root to the path of the project and rewrite to static.
