One of the most common ways to expose a Go application to the world is through a reverse proxy.
NGINX makes this very easy. This NGINX configuration serves 2 different applications listening on port 8001 and 8002 respectively.
server {
listen 80 default_server;
server_name your-domain;
location /go-service-1 {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://localhost:8001;
}
location /go-service-2 {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://localhost:8002;
}
}
Using proxy_set_header X-Real-IP $remote_addr
ensures that you’ll have the visitor’s real address in http.Request.Header.Get("X-Real-IP")
The 8081 and 8082 ports can now stay private, and NGINX serves them from a single point of entry.
