JupyterHub Zero to JupyterHub on Kubernetes
1

Hi,
we are planning to run pre configuration before the actual jupyter server starts.
Yes, We have init container, but we are passing some sensitive information as a configuration, inti container will stay inside the kubernetes.
My objective is run the pod and clean it once its succussed

could you please help me here ?

Also k8s jobs also fine

It’s not clear to me what your requirements are, e.g. what needs to be configured/modified? Is it the jupyter server that needs to be configured, or is it a separate external resource? Is it a problem for the init container to remain if the user can’t access it?

I would like to run a job before the jupyter notebook starts.

JupyterHub spawners support a pre_spawn_hook

Perhaps you could add a hook to create a K8s job?

Yes, I need create k8s job. Can use then pre_spawn_hook ?

It should be possible. pre_spawn_hook takes the spawner as it’s argument. This should give you access to a Kubernetes Client:

I think you should be able to create your own client in a similar way if necessary.
