I have a JupyterHub with a  
[dockerspawner](https://github.com/jupyterhub/dockerspawner).  
I only partly trust the users so that I want to restrict their access to the system as long as it is connected with a reasonable amount of effort.  
Is there a way how I can forbid the default user ‘jovyan’ to install new packages/libraries/…, use the network, open a shell and/or issue commands, including all the standard tools of python (os.system, subprocess, etc.)? Is there any project you are aware of?
