Juju Charmer Summit: Design For Success

Jorge O. Castro

on 23 February 2016

This talk from Juju Charmer Summit 2015 provides a comprehensive introduction to the pieces that make Juju magic happen. We recommend that anyone interested in writing Charms or the process of charming watch this talk as, like Juju itself, it distills best practices into a repeatable formula for success. Topics covered in this video include the basics, the juju dictionary, charm structure, actions, configurations, and testing.

Happy charming!
