Docker, a portable, lightweight runtime and packaging tool, is all the rage these days. It's hard to go to any sort of tech meetup without overhearing people gushing to each other about how cool it is. I'd written some Dockerfiles but wanted to start test driving them. It's actually fairly straightforward using RSpec and ServerSpec. Here's how to TDD a Dockerfile that installs Node on Ubuntu.
Designing and developing VMs as code is at last mainstream. This post is in fact a presentation I give to highlight that we can treat infrastructure code just as we would regular code.
We use TDD/BDD and monitors to spec, implement, test and monitor the resulting VM, keeping its code close to the app's code and as an integral part of it.
DevOps is een reactie op de onderlinge afhankelijkheid van software development (Dev) en operations (Ops). De spreekwoordelijke muurtjes tussen de Dev en Ops afdeling bestaan niet meer binnen DevOps.

They are mostly free, developed by experienced professionals and teachers, and nicely structured. Most courses include hands-on labs that you can perform on the Cloud, on Docker, or VMWare images, or by locally installing the required software. Pass the course test to print your certificate of completion, and to receive and industry-recognized badge!
