Custom containers on Jupyterhub / k8s

[Tony Hirst]

We've been using Jupyterhub on k8s (following the zero2 guide) using one of the official Jupyter docker containers as the base container.

Under the hood, what does Jupyterhub actually require in the container for it to be successfully launched by Jupyterhub?

Is there an example repo or set of docs for a minimum viable container runnable by Jupyterhub, cf the minimum viable Dockerfile for Binderhub?

--thanks
