I'm the author of one of the popular docker images with mkdocs and was wondering if we maybe should join forces on that front and I could help/lead an official docker image for mkdocs if you feel this is something you would like to offer to the community.

I have lead many opensource docker images projects and can offer my assistance with this. Please see the links to my repos and docker hub.
