How to Deploy a Go App Behind Nginx as a Reverse Proxy

Configure Nginx to listen on port 80 and proxy_pass requests to your Go app's local port (e.g., 8080) using the proxy_pass directive.

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://127.0.0.1:8080;
        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;
    }
}

Nginx acts as a traffic cop that sits in front of your Go application. It accepts incoming web requests from the internet and forwards them to your Go app running on a private port. This setup allows you to secure your app, handle SSL certificates, and manage traffic efficiently.
