I'm running a nginx container where it maps to another backend container. When I tried adding upstream block in nginx.conf which is like

upstream backend_servers {
    server backend:8000;
}

The error that is occuring is

[emerg] 1#1: host not found in upstream "backend:8000" in /etc/nginx/nginx.conf:2
nginx: [emerg] host not found in upstream "backend:8000" in /etc/nginx/nginx.conf:2

But If I place the same block in default.conf it works the container is running successfully. What is the issue with nginx.conf file

Is the backend container linked properly in docker? – Gerald Schneider Apr 22 '23 at 20:00
Where do you put default.conf and is the folder you're putting it to included in nginx.conf (like this: `include /etc/nginx/sites-enabled/*;`)? – Radosław Serba Apr 23 '23 at 15:04
