Docker is a free and open-source containerization software that helps to deploy, run applications in a container. The containers are similar to a virtual machine but consume fewer resource, easy to manage and can run anywhere regardless of operating environment it is running in.

Docker uses cgroups and namespace to allow the independent containers to run within a single Linux instance.

This guide will help you installing Docker on Debian 9 Stretch. This guide should also work on the previous version, i.e., Debian 8 (Jessie)

Note: Docker needs a 64-bit version of Debian OS and Kernel version should be at least 3.10.

Add the official Docker repository to the system by running below command in the terminal

echo "deb [arch=amd64] $(lsb_release -cs) stable" |  tee -a /etc/apt/sources.list.d/docker.list
