Hello!
I want to run Jupyterhub with the SystemUserSpawner in the Docker container.
I used the following example for this (https://github.com/jupyterhub/dockerspawner/tree/main/examples/simple)
and only added the following lines to jupyterhub_config.py:
from dockerspawner import SystemUserSpawner
c.JupyterHub.spawner_class = SystemUserSpawner
After starting the JupyterHub container, I created a user “abc” inside the JupyterHub container:
useradd -m abc
After that I logged into the JupyterHub with “abc” and wanted to start a notebook. Here came the following error message:
