Reports and celebrations#

This is a place to make announcements (without a need for discussion). This is also a great place to give shout-outs to contributors! We’ll read through these at the beginning of the meeting.

Agenda items#

Let’s collect all potential agenda items here before the start of the meeting. We will then attempt to create a coherent agenda that fits in the 60m meeting slot. If there are similar items try and group them together.

  • Erik Sundell JupyterHub Helm chart 1.0.0-beta.1 / 1.0.0

  • Isabela Presedo-Floyd (10 min) What’s the status on binderhub #1287? What can I do to support a solution for the communities blocked by the bad (comments on the original issue)

    • Issue for context: jupyterhub/binderhub#1287

    • Alternate PR: jupyterhub/binderhub#1309

    • Supply build token for requests that come from our pages (not the /build API) and exclude requests that don’t have this token

    • Work towards all federation members signing/reading JWTs

  • Samuel Gaist JupyterHub for a reproducible research platform (more context)

    • Hook in kubespawner that allows you to modify the pod that’s about to be launch before it’s launched (?)

    • Yuvi berkeley-dsep-infra/datahub not my code, please don’t judge (copied from chat)

    • Many things can be set as Callables, rather than values, so can be modified for specific users

    • Multi-authentication paradigm: remote user auth, lightweight authenticator that only accepts requests that originate from your ingress point, get username from a header set by that proxy, make another API request to get further info

    • Jupyter Enterprise Gateway: you have a notebook server, and now you want to launch one notebook in an evironment

  • Min RK (5m) repo2docker conda-lock and micromamba

    • conda-lock jupyterhub/repo2docker#1024

      • Simplifies freeze step, faster builds

      • conda-lock only works with conda packages, no pip. solution is to make the pip install a separate step (with separate requirements.txt)

      • Review requested

    • micromamba jupyterhub/repo2docker#1038

      • should save time, related to package installs

      • no longer need to bootstrap a root env for the notebook server. Instead, download a single binary file.

        • right now we create a root environment, then another one for the notebook server and maybe another for a kernel (e.g. Python 2)

    • may cause conflicts since they both touch package installs

    • what are our promises about conda/mamba availability to users?

      • micromamba can install both conda and mamba

      • Tim thinks providing a conda executable out of the box makes sense for backwards compatibility/least surprise

  • Min RK (10m) roles and scopes are ready for main: jupyterhub/jupyterhub#3438

    • Review requested

  • Yuvi (5m) Common Grafana Dashboards for JupyterHub yuvipanda/jupyterhub-grafana

    • Min this sounds amazing!
