Move Rackspace Cloud Servers between Regions (Automation)

Hey!

So I wrote a piece of software (basic) using BASh which exports Rackspace Cloud Servers between regions. It’s pure API CALLS using curl and I’m particularly proud of this piece, since it only took a day. (once I spent the whole of the next day figuring out an issue with the JSON and bash expansion for parameters to export the cloud server image to cloud files).

This is a super rough example of an automation-in-progress for cloud-servers between regions. Once you’ve set the script up, you simply change the serverid, and the script can do the rest, and you can migrate server by server, or perform batch migrates with this.

I’m going to refactor and rewrite it when I have time, but for now, here you are! Enjoy 😀

I hope that this is useful to people, particularly our customers.. when I release a finely tuned version that has commandline arguments support.
