InstaDMG Issues, and Workflow Automation via Your Friendly Butler, Jenkins

Thursday, January 17th, 2013

“It takes so long to run.”

“One change happens and I need to redo the whole thing”

“I copy-paste the newest catalogs I see posted on the web, the formatting breaks, and I continually have to go back and check to make sure it’s the newest one”

These are the issues commonly experienced with those who want to take advantage of InstaDMG, and to some, it may be enough to prevent them from being rid of their Golden Master ways. Of course there are a few options to address each of these, in turn, but you may have noticed a theme on blog posts I’ve penned recently, and that is:

BETTER LIVING THROUGH AUTOMATION!

(We’ll get to how automation takes over shortly.)¬†First, to review, a customized InstaDMG build commonly consists of a few parts: the user account, a function to answer the setup assistant steps, and the bootstrap parts for your patch and/or configuration management system. To take advantage of the(hopefully) well-QA’d vanilla catalogs, you can nest it in your custom catalog via an include-file line, and you only update your custom software parts listed above in one place. (And preferably you keep those projects and catalog under version control as well.)

All the concerns paraphrased at the start of this post just happen to be discussed recently on The Graham Gilbert Dot Com. Go there now, and hear what he has to say about it. Check out his other posts, I can wait.

Back? Cool. Now you may think those are all the answers you need. You’re mostly right, you smarty you! SSDs are not so out-of-reach for normal folk, and they really do help to speed the I/O bound process up, so there’s less cost to create and repeat builds in general. But then there’s the other manual interaction and regular repetition parts – how can we limit it to as little as possible? Yes, the InstaDMG robot’s going to do the heavy lifting for us by speedily building an image, and using version control on our catalogs help us track change over time, but what if Integrating the changes from the vanilla catalogs was Continuous?
