nginx server name path routing

README.md

nginx server name path routing

This example nginx configuration will enable subdomain routing to a single backend path based on the subdomain.

It shows both catch-all routing and specific subdomain routing.

cmd.sh

#!/bin/bash

# use host networking to enable forward to another port on localhost
docker run -v $PWD/nginx.conf:/etc/nginx/nginx.conf:ro --network=host nginx

nginx.conf

events {
  worker_connections  512;
}

http {
    server {
        # route any subdomain to localhost/subdomain
        listen 8080;
        server_name ~^(?<name>\w+)\.example\.com$;
        location / {
            proxy_pass      http://127.0.0.1:8081/$name;
        }

    }
    server {
        # route app3 subdomain to localhost/app3-specific
        listen 8080;
        server_name app3.example.com;
        location / {
            proxy_pass      http://127.0.0.1:8081/app3-specific;
        }
