Hi!  
I’m trying to make it so that users that has spawned a jupyterpod can host webapplications.  
I have two ideas:

1. Edit so that each pod spawns with a service.
2. Edit so the pod spawns with two URL’s, one that consits with the jupyter application and one that is empty so the user can host webapp on it.

Thank you! I have built jupyter-server-proxt:4.1.2 into an image based on this image “jupyter/datascience-notebook:hub-4.0.2” but the extension doesn’t seem to work… I tried to host a basic flask app on 127.0.0.1:4567 but i couldnt connect to it. And i can’t seem to find the Rstudio and Shiny extension 😕

I have checked the pip versions off notebook and jupyter lab and they are  
notebook 7.1.2  
jupyterlab 4.1.5

/user/name-here/proxy/8888

With jupyter-server-proxy installed and enabled as a jupyter server extension, that takes you to a localhost webserver if listening to port 8888.
