Bootstrapping an Ubuntu Server on Rackspace Using Cloud-Init and Fog

Recently at work I needed to figure out how to bootstrap a server image on Rackspace, preferably using Ubuntu’s Cloud-Init package since we already had that working on EC2. I couldn’t find a single person who had done this before, so after struggling for a day or two and finally figuring out that it does indeed work (and it turns out to be pretty simple) I thought I would share the knowledge on how to do it.
