Real Time Collaboration

[betolink]

Is there a way to enable the real time collaboration if I'm using the base image?

https://jupyterlab.readthedocs.io/en/stable/user/rtc.html

Maybe overriding the start entry point to add the --collaborative flag?

@betolink agreed this is a neat feature. I assume you mean using one of these images in a JupyterHub context, and I'm pretty sure that has to be set via JupyterHub/DaskHub helm chart configuration... Pinging @consideRatio and @sgibson91 who might be able to point to the right docs describing how this could be done.

Thanks Scott, looks like it's possible but the hub needs to be configured a bit differently. See: 2i2c-org/infrastructure#810 (comment)

Z2JH based config:

singleuser:
  cmd:
    - jupyterhub-singleuser
    - --LabApp.collaborative=True

General JupyterHub config:

c.Spawner.cmd = ["jupyterhub-singleuser", "--LabApp.collaborative=True"]

Note you may also want to install jupyterlab-link-share extension for a button in the JupyterLab UI for users to use, depending on your setup, it may or may not work for it to fetch a token that grants other access via link sharing.

Sounds resolved, close issue?

Thanks for the guidance, just for future reference it would probably be useful to mention that real time collaboration can be enabled for Pangeo deployments.

I agree, not sure where to document this though without it being written in too many separate places which we end up failing to maintain if something changes.
