Docker Nginx Proxy: how to route traffic to different container using path and not hostname

Question

lets say that now I have different app running on the same server on different path:

• 10.200.200.210/app1
• 10.200.200.210/app2

Answer 1

Default bridge network has gateway on 172.17.0.1. You can use this IP address in your nginx.conf

server {
    listen 80;
    server_name example.com;

    location /app1 {
        proxy_pass  http://172.17.0.1:81;
    }
    location /app2 {
        proxy_pass  http://172.17.0.1:82;
    }
}

They will be accessible using port 80 from outside

You can check your bridge gateway IP address by running command docker network inspect bridge
