Workshop: A Gentle Introduction to Docker for Rubyists by Jason Swett Have you heard about how great Docker supposedly is, but you're not sure exactly what all the fuss is about, or even what Docker is or why people use it? Or maybe you understand what Docker is but you've never worked with it before. In this workshop, you'll learn exactly what Docker is and why you'd want to use it, and you'll come away with your own fully Dockerized Ruby application.
