Pyspark kernel not found in Quay.io/jupyter/pyspark-notebook docker image

Hi,

I launch Jupyter with docker:

%docker pull Quay
%docker run -p 10000:8888 Quay

Once I open the browser, the %pyspark magic is not recognized and “Kernel | Change Kernel” does not give me pyspark as option.

Thoughts ?
