Thanks for the summary. A couple of comments inline. On 02/24/2015 08:48 AM, James Slagle wrote: > Hi Everyone, > > TripleO held a midcycle meetup from February 18th-20th in Seattle.

I should note that just nova booting doesn't get you all the way to a working devtest. You'll still have networking issues running Neutron inside of an OpenStack instance. Also, Devananda pinged me recently about the Ironic IPMI listener service that would probably let us start using this in CI, even if it requires patches that wouldn't be available on real public clouds. As you noted, I haven't had a chance to followup with him about it though. :-( > > We moved onto talking about diskimage-builder.

It's worse than that. The half session was actually in Atlanta. ;-) Again, time. I started implementing some test code and it's even being used in dib already , but I just haven't had time to look into what other functionality will be required for more complete test coverage. : https://github.com/openstack/diskimage-builder/blob/master/diskimage_builder/tests/base.py > > The tripleo-heat-templates was the next topic of discussion.
