How can I forward ports 80 and 443 from an external request through Nginx to ports 81 and 444, respectively?

Question

I have docker containers with my own site and I would like to create external ports 444 and 81 from docker and connect it to a user request from my domain from external nginx on my linux machine. How do I organize the nginx.example1.conf file, I created the containers, I just have to connect the ports, how can this be done in the nginx.example1.conf file and am I doing the right thing?

In short, how do I write the nginx.example1.conf file correctly?

Answer 1

Same as any other reverse proxy configuration for nginX , the only difference will be that the endpoints are on localhost

This is trivial example:

server {
    listen 80;
    server_name foobar.net www.foobar.net test.io www.test.io;

    location / {
        proxy_pass http://localhost:81;
        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_set_header X-Forwarded-Proto $scheme;
    }
}

First, expose the ports on docker (which means they will be visible and accessible from your host on the same ports) Then configure your host nginx as a reverse proxy going to localhost:444 and localhost:81 on the / requests
