# Script: rebuild.sh
# Purpose:  This script is simply a collation of all the steps needed to create the 
#           kubernetes environment on ec2, in a single script.  It was only written for testing
#           purposes, so the environment could be quickly torn down and spun up again during testing.

#This is just a function to create a more visible title
