Add Files to the Container

[RaRam]

Hello,

I have set up jupyterhub for our students using docker.
I want each student who runs a container to open files and data that I upload?
How can I do that?
I guess I have to create a docker image for every change that I make, right?
c.Dockerspawner.container_image= '...' did not work.

Thank you very much!
