If do not know much about Docker, then here is a simple explanation I have for you.

Docker

Portable Application Virtualization.

  • Gives similar results independent of OS Envir

  • Works like VM Images. Miniature VM, just for an Application.

  • Lightweight containers, with all batteries loaded/libraries attached at once.

Once you have basic docker system is ready, you can dock anything you got. Every dock is its own, no dependency on your OS or other dockers. More like Plug and Play.

In BSD we have a similar approach but in layman terms, this is what is called a Docker or a Jail does.

I found this article that explains how to use python as docker for Data Science. So good luck fellows.
