The results are in - containers are hot hot HOT! Everyone's talking about containers, and you've got a pretty good idea of how they work - but here's your opportunity to take that knowledge to the next level and actually get your hands dirty. In this session we'll cover the basics: when and where to use containers, the benefits and limitations, and even get some hands-on experience with the Docker command line.
