Adding Image of Cookie Cutter Analogy

[sstevens2]

The below feedback includes an image I think would be good to include in the lesson. @mkuzak did you make this image? Would you like to contribute it to the lesson?

Was this taught as a stand alone workshop or as part of another workshop / conference? stand alone
What feedback do you have on the lesson?
Most of the things we shared elsewhere. One thing that was not captured anywhere is the analogy we used was that Dockerfies are like a design for the 3D printed cookie cutter, the 3D printed cookie cutter is the image and the cookie is the running container. Djura Smits made a graphic for it.

I think this was @dsmits, Djura can you confirm?

It would be great if we could include this graphic in the lesson material. @dsmits, if you're happy for us to include this, can you let us know if there are any attributions that we need to include for any of the images used in the graphic, or are they all under a CC0 or public domain-style licence? (and we'll of course give you attribution as the author of the complete graphic). Thanks.
