I have Django application with Docker, nginx and gunicorn.

I am trying to use nginx to serve the static files but I am getting 404.

here is my nginx.conf:

events {
    worker_connections  1024;
}

http {

    upstream backend {  
        ip_hash;
        server backend:8000;
    }

    server {

        location /static {    
            autoindex on;    
            alias /api/static; 
        }

        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_pass http://backend;
        }
        listen 80;
    }

}

kubernetes manifest file: Nginx and app are two separate containers within the same deployment.

settings.py

STATIC_URL = '/static/'

STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)

Dockerfile for nginx:

FROM nginx:latest

ADD app/api/static /api/static

ADD config/nginx /etc/nginx

WORKDIR /api

I checked in the nginx container, all static files are present in the /api directory.
