Corrugated Steel Garden Boxes

These corrugated steel garden boxes are a nice addition to our back yard.  We have a pretty big garden area, so these are fairly large (4 ft W x 10 ft L x 3 ft H), but they could be scaled to about whatever size you want. The only limitation is the manufactured dimensions of the corrugated

CentOS 6 to 7 Upgrades for OpenStack Hypervisor Hosts

We’ve published our Ansible playbook and associated scripts we used to handle upgrading our CentOS 6 OpenStack hypervisor hosts to CentOS 7: https://github.com/godaddy/centos7-upgrade-scripts The README describes how it all works, but you will almost certainly have to make some changes for it to work in your environment.  Use at your own risk!  But hopefully this

Nova Cells v1 Support for Server Groups

In a previous post, I described how we implemented Nova Cells v1 support for server group objects using MySQL triggers.  We’d been running that for a while, but needed a real solution (mostly because we created a new cell whose database was in on a different MySQL server.) The patch for Nova is here, and

Duct Tape, Bubble Gum, and Bailing Wire (OpenStack Mitaka Summit, Tokyo)

Here’s a fun talk I did with Matt Fischer, Eric Peterson, and Kris Lindgren at the Tokyo summit. This lightning round talk will present various operators horror stories on weird things needed to keep OpenStack running.  Audience participation is almost assured as we share feats of strength and airing of grievances.

OpenStack Architecture at Go Daddy

We have given a few “show and tell” talks at the last summits and operators’ meetups about the OpenStack architecture we’re running at Go Daddy. We thought we’d some more in-depth posts to dive into it further.

OpenStack Architecture at Go Daddy, Part 2: Neutron

As mentioned previously we do some customizations in Neutron in order to support our layer 3 networking model.  There are no tenant networks, tunneling or overlays.

OpenStack Architecture at Go Daddy, Part 3: Nova

After our first two posts detailing OpenStack architecture at Go Daddy, this third one in the series focuses on Nova.

Using nova policy.json to Enforce Availability Zone Selection

We recently had a requirement to enforce selection of an availability zone* when booting instances in nova.  There’s no way to do this in the stock API, we didn’t want to modify code, and a waffle seems like overkill.  So I spent some time playing with policy.json config to see if we could enforce this there:

Why the OpenStack Summit is Valuable for Me

The Liberty Summit going on this week in Vancouver is my third consecutive OpenStack Summit.  After working with OpenStack for almost two years, I no longer feel like a noob when I’m in the company of everyone else at the Summit. As things are winding down here (most of the operators sessions wrapped up yesterday),

Highlights from OpenStack Liberty Summit, Vancouver

My tally of favorite talks during the OpenStack Liberty Summit. Thursday By Thursday, you can start to feel the Summit winding down.  For the most part all the operators stuff is done, and many of the remaining time slots are project work sessions.  However, there are still some highlights from the general conference tracks.
