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 ( - 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,

" 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:

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.)
