I have a django container and an Ngix container. they work fine with docker-compose, and now im trying to use the images with kubernetes. Everything works fine, except the fact that the nginx container cannot connect to the uwsgi upstream. No response is being returned.

Here are my configuration:

# Nginx congifuration
upstream django {
    server admin-api-app:8001 max_fails=20 fail_timeout=10s;  # for a web port socket (we'll use this first),
}

server {
    # the port your site will be served on
    listen  80;
    server_name server localhost my-website-domain.de;
    charset     utf-8;


    location / {
        uwsgi_pass django;
        include     /etc/nginx/uwsgi_params;
    }
}

# Uwsgi file
module          = site_module.wsgi

master          = true
processes       = 5
socket          = :8001
enable-threads  = true
vacuum=True
