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.
Name: Your report or celebration
[name=Min (not here)] just published JupyterHub 2.0
RBAC (role-based access control): More fine grained permissions in the hub
How parameters are passed by the spawner, now environment variables only: may be a breaking change for some. But it’s a lot more future-proof
JupyterLab is the default
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.
All: Standing project items:
Batchspawner check-in: Issues and PRs
Wrapspawner check-in: Issues and PRs
Having to vivify the
Start a PR to fix this (Rollin will)
Tag all relevant issues in that PR
Have discussion in the PR about this to see if there’s a better fix
JupyterHub 2.0 tests
Felix tested w/BatchSpawner. Didn’t need any code changes to work! How encouraging!
Folks will test with WrapSpawner
JupyterLab 3 and Batchspawner - status?
Need to redo how we do singleuser launch?
Notebook servers on login nodes
Can you put remote kernels on compute nodes
Use kernel gateway to connect
BatchSpawner for this?
Not set out to support this…
Could be modified
Job would run kernel gateway
Lab needs to know how to find it
What if there are multiple jobs running
Notebook on the login node
Job is running another notebook server for the kernels
Could be hacked, but is this a thing?
