Example of using host network

• !!! The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.
• Run Nginx from localhost:80 but other resources isolated from a host

docker run --rm -d --network host --name my_nginx nginx

• Access Nginx by browsing to http://locahost:80/.
