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!

How to suppress comments when performing git diff on .po files.

Taken from: http://stackoverflow.com/questions/2006351/gettext-po-files-under-version-control

Changes in the codebase can alter line numberings given in .po 'comments'. While such changes should be committed they make obsecure the actual translation changes made, and make auditing them difficult.

1. Create /usr/local/bin/strippocomments as given in this gist.
