Understanding Docker can be difficult or time-consuming. In order to spread knowledge about Cloud technologies I started to create sketchnotes about Docker. I think it could be a good way, more visual, to explain Docker (and other technologies like Kubernetes and Istio).

We continue the series of Docker sketchnotes with tips about Dockerfile: the difference in CMD instruction between string and JSON syntax.

As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-).

If you are interested, I published all the sketchnotes on Docker (and new ones!) to make a "book" of 93 pages: "Understanding Docker in a visual way".
