Network, expose port

by default the 80 port is only exposed inside the CT, we have to export/expose it outside the CT by binding it to an external port, option -p 8080:80 (a privilege dialog might open to allow firewall access)

it is more convenient to name CT instead of using random IDs, option –name

C:\Users\jehan>docker run -d --name webApp -p 8080:80 nginx:1.27.2
