NAME: What you’d like to update on
Rollin: Notes from last meeting on team-compass, PR/issue
Kevin: Hit another sysadmin blocking issue at NCAR, does anyone have interest in setting up a “mock HPC system” on AWS or GCP or otherwise for dev/testing of JupyterHub-based services? (e.g., Binder for HPC and more) If yes, then we can discuss below.
For another local test, I [name=rkdarst] used https://github.com/giovtorres/docker-centos7-slurm (also https://github.com/giovtorres/slurm-docker-cluster for multi-container)
For more elaborate setup, have a look at Magic Castle: https://github.com/computecanada/magic_castle which can setup a Slurm cluster + JupyterHub in AWS, Azure, GCP and OpenStack
Félix-Antoine: Where are we with batchspawner PR #187 - https://github.com/jupyterhub/batchspawner/pull/187 ?
Michael: Worked out the kinks in the CI for batchspawner, and there’s a release out on PyPI. Never had a wrapspawner release on PyPI but Michael is look at getting that out on PyPI (make sure no issues,
Richard: Made an action to check tag against version in the package to make sure they are the same. Seems like a common need, useful in his case.

No. Original PR was handling the unknown job state etc

Question about whether unknown state should be in JupyterHub: No, see https://github.com/jupyterhub/jupyterhub/issues/3171
Looks like it’s OK to merge…
How soon to do a release?
Merge (done now), give people a week to bang on it
