 # This created a container called ubuntuDev using the 'ubuntu:14.04' image from docker hub and runs bash interactively. 
 # -e ensures your networks are mapped correctly
 # Also '-v' ensures that your local directory at ~/Code is mounted as /Code within the container, 
 #   so you can actually write code in your OS and compile within docker. 
 
 # Now, once you exit the bash session that was created, to resume and reload the same container, do this
