Since Docker was introducted to the market in 2012, it has become one of the fastest-growing technologies. For many Developers or system administrators, Docker is undeniably a staple in every toolchain, since its utility changes and adapts to every profile and need. Developers can focus on writing code without worrying about the final user’s system where it will be executed on, while also offering a potential gain of time by using already existing programs designed to run in Docker containers as a part of the final application. DevOps engineers can also benefit from the implementation of Docker for its flexibility, shareability and cost efficiency since it reduces the number of needed systems.

This technical note will introduce Docker tool and detail from scratch the installation and configuration steps, different ways of interacting with Docker hub and containers using Docker commands.
