On Tuesday, August 21st, DreamHost is hosting a couple of Chef-specific presentations. First up is Aaron:
Chef's New Existential Angst: Exploring Whyrun Mode
Aaron J. Peterson - Consulting Technical Evangelist and Chef Instructor
"Whyrun" is a new feature in Chef - and is one of the oldest and most requested features - see CHEF-13 at tickets.opscode.com (http://tickets.opscode.com/) - argued about and discussed often. While similar to the concept of a "no-op" or "dry run" mode in other tools, it addresses some of the real concerns that arise when trying to "fake it". To quote Dan DeLeo,
"...in addition to checking the state of the system and telling you what it would do, Chef now also has a system for providers to declare explicitly a set of assumptions they'll make about the system, and to inform the user when these assumptions don't hold..."
You not only see what Chef would do with a particular resource, but what it assumes earlier actions *should* do in order for that resource to succeed.
Interesting stuff, and we'll take it for a test drive.
There will also be a presentation by Carl Perry of DreamHost, but we'll fill in details later.
Deploying OpenStack Using Chef
Carl Perry - DreamHost Cloud Architect
(more details to come)
We're teaming up with our friends from OpenStack LA, who are hosting a OpenStack Cookbook Hackathon on the same day at the same Downtown location: http://www.meetup.com/OpenStack-LA/events/75878692/
The presentations above start at about 6:30, after that Hackathon.
Chefs should attend both events!
Aaron Peterson may also hold a Chef training session (beginner-intermediate level) near the end of that week. As above, we'll update with information as we get it.
(We still plan to hold our regular meetup on our regular day: Monday, August 27th. We'll update if that changes and we make this event this month's only meetup.)
