Looks like a huge improvement from the older version. Thanks for working on it.

I works great in my initial test, and will try use this setup more often, going forward we can look to dockerize the mkdocs as well.

I've left minor cosmetic suggestions.

In my experience, the --watch command doesn't sync the file properly. I changed a html file and it didn't update until I built the image again.

I don't much experience with it, saw it here first time.

@theskumar I have attempted to mount the hypha sub dir and sync everything else. Seems to work. Please try it out when you have time.
