Continuous Integration with Jenkins on Amazon EC2

This documented is a slightly adapted version to this one: https://gist.github.com/jsuwo/9038610 by Jeff Shantz. He has a fantastic video series on setting up Jenkins on AWS EC2 here: https://www.youtube.com/watch?v=1JSOGJQAhtE&feature=youtu.be&ab_channel=JeffShantz

AWS EC2 set-up

• Choose 1-2GB Ubuntu Server
• Create new security group and Enable HTTP (& leave SSH open)
• Launch!
