- You cannot set ACCESS-CONTROL to '* for jupyterhub', it is not working - See https://github.com/jupyterhub/jupyterhub/issues/1087
- don't change port 8000 or 8081, JupyterHub will talk to these two ports and there is no clear way to setup.
possible issue if you change: kernel not found. - DO NOT USE latest singleuser image, THIS DOES NOT WORK
see https://github.com/jupyterhub/dockerspawner/issues/155
Known working images: jupyterhub/singleuser:0.7, jupyter/r-notebook:93b880cb801c - get error: Permission failure checking authorization, I may need a new token jupyterhub.
no other solution besides restart. it is not related to jupyter/r-notebook. make sure all the user containers are deleted, using "docker ps -a"
