Docker is a powerful way to deploy application and server on top of an existing host. Not like traditional virtualization, Docker offers a more sophisticated way to do virtualization. Docker can be installed on almost any modern operating system including Windows and Linux. Today, we are going to learn how to install Docker on Ubuntu 18.04 Bionic Beaver.
