How to run several web scripts on 1 hosting, on different subdomains?

Question

go

on a virtual host.
In particular interested in golang.

Answer 1

Write Go lang services that you need.
Each service listens on a different port.
Set up a web server, such as nginx, and set up virtual hosts that forward requests to Go lang services.
The nginx config will look something like this

server {
    listen *:80;
    server_name yourdomain1.com; # домен, который вам нужно
    ...
    location / {
        proxy_pass http://127.0.0.1:9000; # IP адрес и порт, на котором слушает сервис Go lang.
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

server {
    listen *:80;
    server_name yourdomain2.com; # домен, который вам нужно
    ...
    location / {
        proxy_pass http://127.0.0.1:9001; # IP адрес и порт, на котором слушает сервис Go lang.
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

You just run it and it works. It is possible without containers at all.
