Last week, around 30 people from around the world met in Darmstadt, Germany to discuss various things about OpenStack and its automatic testing mechanisms (CI).
The meeting was well-organized by Marc Koderer from Deutsche Telekom.
We were shown plans of what the Telekom intends to do with virtualization in general and OpenStack in particular and the most interesting one to me was to run clouds in dozens of datacenters across Germany, but have a single API for users to access.
There were some introductory sessions about the use of git review and gerrit, that mostly had things I (and I guess the majority of the others) already learned over the years. It included some new parts such as tracking “specs” – specifications (.rst files) in gerrit with proper review by the core reviewers, so that proper processes could already be applied in the design phase to ensure the project is moving in the right direction.
On the second day we learned that the infra team manages servers with puppet, about jenkins-job-builder (jjb) that creates around 4000 jobs from yaml templates. We learned about nodepool that keeps some VMs ready so that jobs in need will not have to wait for them to boot. 180-800 instances is quite an impressive number.
And then we spent three days on discussing and hacking things, the topics and outcomes of which you can find in the etherpad linked from the wiki page.
I got my first infra patch merged, and a SUSE Cloud CI account setup, so that in the future we can test devstack+tempest on openSUSE and have it comment in Gerrit. And maybe some day we can even have a test to deploy crowbar+openstack from git (including the patch from an open review) to provide useful feedback, but for that we might first want to move crowbar (which is consisting of dozens of repos – one for each module) to stackforge – which is the openstack-provided Gerrit hosting.

Overall for me it was a nice experience to work together with all these smart people and we certainly had a lot of fun
