<![CDATA[Jupyterhub - single user notebook servers shuts down]]>I would like to use the Jupyter Scheduler extension.

https://jupyter-scheduler.readthedocs.io/en/latest/users/index.html#installation

The installation is working fine.
I then set up a job that runs once a day. This also works without any problems.

However, I have noticed one issue. If I don't use the app for a few days, my notebook server is shut down and thus the job will not run again until I start the notebook server.

Is there a way to prevent the Notebook Server from shutting down in the Jupyterhub settings?

Do you see any logs that it is removing a container ? Cloudron itself doesn't remove any containers.

I could not find jupyterhub-idle-culler in the list of 'pip list' in the terminal of the Jupyterhub container.

The default package doesn't enable all that, so I am just asking if you have enabled it in your own.

This is not the case.
There must be something running in the background of Jupyterhub that stops the notebook server/Docker container as soon as there is a certain amount of inactivity.

When the app gets updated to use the latest notebook, the existing notebooks are shutdown so that they can be started with the newer image. I suspect that maybe the app is getting updated in the middle and thus the notebook is getting shutdown.

Is your job able to start up the notebook server automatically?

The Cloudron package has no code to shutdown notebooks
