How To Install Docker on Debian 9

In this article, we will be installing and setting up Docker on a Debian 9 VPS.

Docker is an open-source application that provides lightweight operating-system-level virtualization through the use of containers. It is specially designed to increase the productivity of most IT operations by making virtualization easy to use. Containers are in essence a set of software packages that run as one application that’s isolated from other applications. Developers, System Administrators, and the like take advantage of this feature by spawning containers wherein they can create, deploy, and run applications without needing to create another virtual machine, which greatly affects productivity and cost.
