Understanding Docker can be difficult or time-consuming. In order to spread knowledge about Cloud technologies I started to create sketchnotes about Docker, then I've auto-published a book and since now I've started a new serie of video! :-)

I imagined a serie of short videos with a mix of sketchnotes and speech.

I think it could be a good way, more visual, with audio & video to explain Docker (and others technologies).

The fourth episode is focused on another very important Docker object: Dangling images.

The video is in French BUT I done the subtitles in english (and french too).

And the bonus of this article, here you can find all the sketchnotes and illustrations of the video:

If you liked the video and are interested to watch another ones, please give me some feedbacks (and you can also subscribe to [my Youtube channel](https://www.youtube.com/c/AurelieVache), if you want to ❤️).

I can also give you, in an article, the full english transcript and sketchnotes in high quality, about this video, if you are interested.

If you are interested, I published all the sketchnotes on Docker (and new ones!) to make a "book" of 120 pages: ["Understanding Docker in a visual way"](https://aurelievache.gumroad.com/l/understanding-docker-visual-way).

If you like theses sketchnotes, you can follow me, I will publish others sketchs shortly :-).
