In this tutorial we will show you how to install and configure Docker on Debian 8 Jessie server. For those of you who didn’t know, Docker is an open-source project that automates the deployment of the application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets etc. Docker is written in a Go Programming language and is developed by Dotcloud. It is basically a container engine which uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS.
