Integrate with jupyter/notebook with jupyter-nodejs

[jan-osch]

Hi ! I have been working on creating a docker image that would integrate jupyter/notebook with a node-js kernel. I am beginner in both jupyter and docker, so it is challenging for me.

I managed to install everything and get the notebook running. Jupyter recognizes the Node.js kernel but when I open a new notebook with it i get kernel error and a stacktrace like this:

This is my Dockerfile. Could you share some insights what am I doing wrong?

@jan-osch I am happy to hear that you are using jupyter-notebook and got node.js running. Might be interesting for some other people as well.

One note of caution: the containers are not completely stabilized yet, we are still fixing problems and errors (as you might have noticed). It will take a couple more days.
