1. Create new container  
   a) docker run -i -t ubuntu /bin/bash
   b) docker run --name rails_dev_container -i -t ubuntu ubuntu /bin/bash
   The command line flags - i -t provide an interactive shell in the new container

2. Show running docker containers    ==> docker ps

3. Show list of current containers   ==> 
   a) docker ps -a   (Show all containers, both stopped and running)
   b) docker ps -n x (shows the last x containers, running or stopped, ex: docker ps -n 5)
