The following is a blog post version of a talk presented at pyconau 2018. Slides for the presentation can be found here (as Microsoft powerpoint, or as PDF), and a video of the talk (thanks NextDayVideo!) is below: OpenStack is an orchestration system for setting up virtual machines and associated other virtual resources such as…

The last week for linux.conf.au 2019 proposals!
Dear humans of the Internet — there is ONE WEEK LEFT to propose talks for linux.conf.au 2019. LCA is one of the world’s best open source conferences, and we’d love to hear you speak! Unsure what to propose? Not sure if your talk is what the conference would normally take? Just want a chat?…
Rejected talk proposal: Design at scale: OpenStack versus Kubernetes
This proposal was submitted for pyconau 2018. It wasn’t accepted, but given I’d put the effort into writing up the proposal I’ll post it here in case its useful some other time. The oblique references to OpensStack are because pycon had an “anonymous” review system in 2018, and I was avoiding saying things which directly…
Accepted talk proposal: Learning from the mistakes that even big projects make
This proposal was submitted for pyconau 2018. It was accepted, but hasn’t been presented yet. The oblique references to OpensStack are because pycon had an “anonymous” review system in 2018, and I was avoiding saying things which directly identified me as the author. Since 2011, I’ve worked on a large Open Source project in python….
Adding oslo privsep to a new project, a worked example
You’ve decided that using sudo to run command lines as root is lame and that it is time to step up and do things properly. How do you do that? Well, here’s a simple guide to adding oslo privsep to your project!
How to make a privileged call with oslo privsep
Once you’ve added oslo privsep to your project, how do you make a privileged call? Its actually really easy to do. In this post I will assume you already have privsep running for your project, which at the time of writing limits you to OpenStack Nova in the OpenStack universe.
On Selecting a Well Engaged Open Source Vendor
Aptira is in an interesting position in the Open Source market, because we don’t usually sell software. Instead, our customers come to us seeking assistance with deciding which OpenStack to use, or how to embed ONAP into their nationwide networks, or how to move their legacy networks to the software defined future. Therefore, our most common role is as a trusted…
So you want to setup a Ceph dev environment using OSA
Support for installing and configuring Ceph was added to openstack-ansible in Ocata, so now that I have a need for a Ceph development environment it seems logical that I would build it by building an openstack-ansible Ocata AIO. There were a few gotchas there, so I want to explain the process I used. First off,…
Things I read today: the best description I’ve seen of metadata routing in neutron
I happened upon a thread about OVN’s proposal for how to handle nova metadata traffic, which linked to this very good Suse blog post about how metadata traffic is routed in neutron. I’m just adding the link here because I think it will be useful to others. The OVN proposal is also an interesting read.
Nova vendordata deployment, an excessively detailed guide
Nova presents configuration information to instances it starts via a mechanism called metadata. This metadata is made available via either a configdrive, or the metadata service. These mechanisms are widely used via helpers such as cloud-init to specify things like the root password the instance should use. There are three separate groups of people who…
