Ask quick dev questions about JupyterHub, the multi-user server for Jupyter notebooks. Use discourse.jupyter.org for user questions, support, and discussion.
i want to fetch uid and gid from LDAP and map the uid as a variables in the chart to single-user pod like this username variables

Traefik can be used to do soo many things, but if you have Traefik acting as an Ingress controller, that inspects k8s Ingress resources, and routes traffic based on that --- then absolutely, you just make z2jh create the Ingress resource. Then you can make it handle the TLS termination for example, which otherwise z2jh can do for you by deploying a Traefik running in a pod named autohttps.

I wrote a medium article how to deploy JupyterHub On-Premise on Kubernetes and which technologies can be chosen. Z2JH has a very detailed documentation how to do it on Cloud, therefore thought to share some of my experience how I did it On-Premise.
Maybe it will be helpful for some :)

We have an issue on our JupyterHub setup causing sometime a user no more able to save it's notebook.
When the problem come, a dirty fix is for the user to:
- don't close the notebook tab,
- switch to another tab,
- access any other page of her/his JupyterHub server,
- re-switch to the notebook tab,
- save is working again.
The log messages when doing this workflow are like:
Is this problem something already known? Is there a way to fix it?[W 2021-09-24 10:25:15.554 SingleUserNotebookApp auth:314] No Hub user identified for request [W 2021-09-24 10:25:15.555 SingleUserNotebookApp auth:552] Token stored in cookie may have expired [W 2021-09-24 10:25:15.556 SingleUserNotebookApp handlers:617] Forbidden ... starting from here, all save/edition of the notebook failed ...

jupyter notebook command?
@gaelle:gluten.space yes, it is possible, but I probably wouldn't recommend doing that since the link would continue to work and allow anyone to become the target user if they visited the link. Issuing a token for the user and then visiting /hub/user-redirect/?token=... should work, though.
We don't have expire-after-use tokens like most magic-link login emails do, which I think would be the best way to do something like this.

get_token(self) in the Handler class to look in the url param, you can call user = self.get_current_user_token() and be off.
