It is good practice to run your go web server in a non-root environment. However, if your web server isn’t root then it can’t bind to port 80. One solution is to use nginx as a proxy to listen on ports 80 and 443 for http/https traffic and forward them to your go server running on a higher port such has 8000, 8080 or 9000. Digital Ocean has a good tutorial on how to install Nginx.
