RTC support for Jupyterhub

[Atharex]

There have been recent updates to jupyterlab's real-time collaboration (RTC) which seems to be in a working state now: https://jupyterlab.readthedocs.io/en/stable/user/rtc.html

Are there any plans to include this also in ZTJH?

There was already a discussion on the Jupyterlab forums and a blueprint of a working example created for a standalone jupyterhub: https://discourse.jupyter.org/t/plans-on-bringing-rtc-to-jupyterhub/9813/7 https://github.com/ktaletsk/jupyterhub-rtc-config-wrapper

Yes, absolutely. I think it will be roughly:

• release JupyterHub 2.0 with RBAC (this month or next)
• identify access patterns, custom scopes/requests required to use these scopes to manage granting sharing access to users
• implement necessary support, likely on both the jupyter_server and jupyterhub side

It's unclear if there will be anything specifically required in z2jh or not. My initial inclination is no, but we'll see.

One thing we will probably want, which is a JupyterHub 2.1 or 2.2 goal, is the ability to manage role assignments via REST API (or if sharing ends up being its own endpoint) so that a user can grant other users access to their own server via an API request. That's an admin-level operation right now.

Changing roles at runtime gets complicated, because then the configuration is necessarily inconsistent with the database, but we need to determine which should win - an updated configuration, or a deliberate rest-api change.

+1 !

Any updates on this?

There's a Discourse thread linked in the original post: https://discourse.jupyter.org/t/plans-on-bringing-rtc-to-jupyterhub/9813

Since this involves multiple Jupyter components it's probably best to continue the discussion there.

FWIU, RTC also works with JupyterLite?

There's a BinderLite effort: https://github.com/manics/binderlite-builder

For schools, BinderHub with auth and instructor-manageable RTC would probably be enabling for teachers

Hello,

I was planning to enable RTC on my jupyterhub environment running in Kubernetes, but after reading the discourse thread I realized that it's not yet fully supported for this type of installation.

Any plan to add support of this in the near future ?

RTC works with JupyterHub as long as the permissions are relatively static (users cannot yet manage access to their own servers). If users have the access:servers permission for a given server, installing jupyter-collaboration with jupyterlab 4 should enable RTC.

Okay I will take a look, thank you !

Does RTC work with JupyterLite; such that JupyterLite users can replay a collaborative notebook without installing libraries?
