Document how to connect a JupyterHub to a binderhub with jupyterhub-fancy-profiles

[yuvipanda]

This is part of the work with the GESIS grant, following up on https://2i2c.org/blog/2024/jupyterhub-binderhub-gesis/.

This is a follow-up to https://github.com/2i2c-org/binderhub-service/pull/72.

Me and @simaattar2003 worked through this in a video session a few weeks ago. I need to encode that in a document, so she can try it out end to end herself. We have a meeting scheduled for Thurdsay Feb 8, so this needs to be done before that.

Things that would need to be documented:

• [ ] How to connect a jupyterhub to the binderhub by setting up the appropriate service entry as well as base_url
• [ ] How to get jupyterhub-fancy-profiles enabled on the hub - this may involve a custom image, or something else. tbd.
• [ ] Set up a sample profile to make sure the setup in imagebuilding-demo is replicatable

When we were testing this, we just used the hub image that is built by 2i2c for use in our hubs. However, I don't think this is a good long term plan. So I'm going to autobuild images based on the z2jh hub image but with fancy-profiles setup.

This went great! Here are some notes on changes to make in the docs

• Note that you may also use a LoadBalancer instead
• Turn the paranthetical into a sentence in the paragraph about creating the artifact registry
• It says 'click next' in the service account, but it's actually a button named 'continue' now
• Clarify how to indent the service account key correctly
• Formatting on the sub-bullet points on z2jh service account stuff is not formatted correctly
• Add that we're going to shared loadbalancer
• -o name will put service/ in front of the names of services, and we should clarify that
• Clarify how exactly to find latest version of the helm chart
• Make a note that you must add a slash at the end of /services/binder
• Clarify how the latest tag or appropriate tag for z2jh-fancy-profiles is to be set up
• Note about using quotations in the yaml around tag
• Remove YAML anchor in the config
• Note about how folks may validate config?
• Clarify that the services part should still be there under hub.config - not be replaced
• Should clarify that you should not go to /services/binder for final test
• Document that any username & any password will get you in

I've incorporated most of these suggestions into https://github.com/2i2c-org/binderhub-service/pull/82 now.
