QuintupleO

Status

It's been a while since my last OVB update, and I've been meaning to post a network diagram for quite a while now so I figured I would combine the two.

In general, the news is good. Not only have I continued to use OVB for my primary TripleO development environment, but I also know of at least a couple other people who have done successful deployments with OVB. There is also some serious planning going on around how to switch the TripleO CI cloud over to OVB to make it more flexible and maintainable.

Because every decent project related to OpenStack has to go through at least one rename. ;-)

Actually there are practical reasons behind this rename. First, it turns out a lot of people think you're joking if you start talking about QuintupleO (and to be fair, the name started out as a very tongue-in-cheek thing). More importantly, OpenStack Virtual Baremetal has applications outside of just TripleO, which is a fact that tends to get lost in the Stack-ception of the old name.

As promised, here is the demo video for QuintupleO.

Yep, that's right. I've successfully deployed a cloud in a cloud using a third cloud. I have a video, but I'm not sharing it just yet because it was done using some slightly broken pre-release overcloud images. On the plus side they had exactly the same issues as the non-QuintupleO environments so I'm declaring success. :-) As soon as I have a chance to re-record with a fully functioning overcloud I'll post it here.

As discussed in my last update on QuintupleO, the biggest blocker for getting that working was a way to allow Ironic to control OpenStack instances. Since then I have been made aware of the pyghmi project, which provides a way to implement IPMI interfaces that do arbitrary things on the back end. It currently includes a couple of examples in its bin directory for noop and virsh implementations.

Edit: Updated 2015/3/19 with more current diffs of my changes.

At the Atlanta OpenStack Summit we had a session on something called QuintupleO, otherwise known as "TripleO wasn't confusing enough, let's add another layer" :-) Barring a few specific concerns from other teams, which I believe have now been addressed to their satisfaction, everyone seemed to be on board with the idea. But what exactly is QuintupleO, and where does it stand today? Read on to find out.
