Docker Quick Tutorial

Docker Quick Guide:

Docker is a tool that is designed to benefit both developers and system administrators, making it a part of many DevOps (developers + operations) toolchains. 

For developers, it means that they can focus on writing code without worrying about the system that it will ultimately be running on. 

It also allows them to get a head start by using one of thousands of programs already designed to run in a Docker container as a part of their application.

1. Clean up cached containers and images and have a fresh/clean staring:

   Cleanup Expand source

   [xinzhang@localhost ~]$ docker container rm $(docker container ls -aq)
   
   
   [xinzhang@localhost ~]$ docker image rm $(docker image ls -aq)

2. Pull Docker image
