In Fudcon Pune 2015 we had conducted a Docker introductory workshop. It was well attended and we got positive feedback about it. While preparing for the Linux container track in Fudcon we had decided that we will put all the documentation in github. The idea was to keep the content open for collaboration so that others can contribute and reuse the content. Thanks to Neependra for the idea.
Here is the github link which has the workshop content.
The github project also contains some useful material e.g. Hands on Kubernetes which you might useful.
This workshop will take around 3 hours to complete. This is really useful If you are new to docker and wants to learn by doing some hands on.
