NB Grader on Kubernetes

[Jason Kuruzovich]

Hello,

I’m trying to utilize NB grader with an instance of Jupyterhub on Kubernetes, created using Helm (https://github.com/jupyterhub/helm-chart). 

 

I’ve rebuild the singleuser docker image to include the latest version of NB grader, adding the nbgrader extension. 

 

As far as I can tell, NB grader seems to be installed and functioning appropriately.  However, I've realized that nbgrader requires a directory to exchange files between users that is writeable by everyone but not readable, by default /srv/nbgrader/exchange.

Any idea how this might be possible?  My understanding is that each individual is getting customized data storage linked to their container but that there is nothing which could currently be used to connect them.  I just created an issue and the project has been really responsive, but I thought I'd bing this group to see if anyone had already developed solutions.

Best,
Jason

Hi Jason,

I am not sure if anyone is currently using nbgrader with Kubernetes, and I haven't used Kubernetes myself so I can't speak to that. When I used nbgrader with docker swarm, we were using NSF on all of our node servers which gave the students access to the exchange directory. You might be able to do something similar by having a shared data container that is linked to all the student containers, but I am not totally sure if that would work.

Hope that helps!

Cheers,

Jess

Jessica,

Thanks for the reply.  

So no problem…I just need an alternate way to distribute and collect files.  So it seems that the LMS is obviously one way, but I’m curious whether anyone has done it with Github Classroom?  https://classroom.github.com

Thanks again. 

Best,

Jason

Jason, what do you mean by "the LMS"?

Have you considered CoCalc for distributing and collecting files?

By the way CoCalc recently moved to using Kubernetes.

Here is a tutorial on Teaching with CoCalc:
