Docker has become the essential technology for building/packaging our applications in images and running them in containers. But understanding Docker can be difficult or time-consuming.

Two years ago I asked myself how I imagined the concepts of Docker: an image, a layer, a registry… and then I created a new way of explaining Cloud technologies.

In the first part of the talk, I will tell you a story, I will tell you my story. How, during more than two years, I worked every evening/nights/wee-end to explaining Docker in sketchnotes, in blog posts, videos and finally published everything (and more) in an illustrated book of more than 250 pages (with all the concepts included Docker compose and extensions) and why I continue to do it.

And in the second part, I will explain Docker concepts to you ... in a visual way :-).
