Creating a home OpenStack lab with RDO and a couple spare laptops

Since part of my daily job is related to maintaining the Packstack codebase, I routinely run OpenStack installations every day… in a single VM, in my laptop, just to delete them a couple hours later. But sometimes I need to test some script or code over a live OpenStack installation, and I’d like to have a more stable environment to play with. Sure, there are public environments like TryStack, but I had a couple old laptops lying around, so why not play with them?

So the plan for today is to take these two laptops, install RDO on them, and have them be part of my home network, so that instances can connect to the Internet and get packages from the official repositories, and I can connect to them from my laptop using a floating IP in the same IP range as my home network.

Writing Packstack plugins

As part of the onboarding process to the Packstack team, I had to understand how the Packstack internals work. There is no official documentation describing it, so when I learnt that some other colleagues would help us writing new plugins, I thought it would be a good idea to create something in written form. Using a series of blog posts by E.Nakai (available here) and some of my own reverse-engineering as a starting point, I have created this blog post.
