Understanding Docker can be difficult or time-consuming. In order to spread knowledges about Cloud technologies I started to create sketchnotes about Docker. I think it could be a good way, more visual, to explain Docker (and others technologies like Kubernetes and Istio).
We continue the serie of Docker Sketchnotes with a focus about a useful (internal) tool: Scan.
It's not a tool you can find in Github, or in a Git repository, but it's a feature in Docker (only in Beta in Docker Desktop Edge for the moment).
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".
As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-).
