Understanding Docker Networking<\/h2>\n

Prima di addentrarsi nelle reti esterne, \u00e8 fondamentale comprendere le basi del networking Docker. Docker utilizza per default un modello di rete bridge, dove ogni container<\/a><\/span>Containers are lightweight, portable units that encapsulate software and its dependencies, enabling consistent execution across different environments.
