From #10:

• Building the Dockerfile
• Putting together the GitHub authenticator and Docker spawner
• Mounting the Docker socket and certificates
• TLS

@smashwilson Should we do this in time for PyCon?

FYI I am working on something very similar. https://github.com/jupyterhub/jupyterhub-carina/issues/3

There are two aspects to this:

1. Run JupyterHub on Carina. This involves a lot of fun with let's encrypt, etc. That's what I'm doing now.
2. Spawn user servers on their own cluster. This work is done and is in the jupyterhub-carina python package. See that repo's readme for instructions.

@everett-toews I have an initial prototype of #1 at jupyter/jupyterhub-carina#5. Still needs more work but it does work and there's enough there to talk about.

@carolynvs I'll give this a shoutout tomorrow. Thanks!
