Have you ever tried to get all of the necessary bits and pieces needed for a software program from one machine to another? Shipping a can of coffee beans half way around the world was easier. Then came Docker and solved that problem. Docker allows you to build, ship and run any app, anywhere. It automates the deployment of apps inside software containers using various features of the Linux operating system – works on Windows and Mac systems too.
Stop driving yourself crazy and learn the Docker concepts, tools, and commands. You will familiarize yourself with the Linux operating system, come to grips with Docker Hub, even create your own WordPress site with Docker.
