Container as kernel?

Hey all,
A customer has asked if it is possible to specify a container image with their python application as a kernel / to make a notebook out of a container image.

Off of the top of my head, this is not possible, and I recommended they just use the container via a console launcher (for those users who do not operate a workstation, etc).

However, I thought it worthwhile asking, in case this might be on the roadmap.

Many thanks

Would repo2docker help?
