Full Stack Journey Episode #2: Matt Oswalt

In Episode #2 of the Full Stack Journey podcast, my guest is none other than Matt Oswalt. You may know Matt as the primary author at Keeping It Classless, or as @mierdin on Twitter or GitHub (he also has a YouTube channel and a podcast of his own).

In this post I’d like to show you how to use a JSON-formatted data file to create and configure multi-machine Vagrant environments.

I’m simply presenting it here as an alternative option to the approach of using YAML with Vagrant for multi-machine environments (some people may prefer JSON over YAML).

An Improved Way to use YAML with Vagrant

In this post, I’d like to share with you an improved way to use YAML with Vagrant.
