We're using beta APIs removed in k8s 1.26

[minrk]

got an email from GKE that we are using some beta APIs removed in 1.26 that will prevent upgrade.

Not a pressing issue (1.25 EOL is in 10 months), but writing it down so we don't forget. I don't know what beta APIs we are still using, but should be easy enough to find.

UPDATE: found relevant github issue for releasing new helm chart: jupyterhub/zero-to-jupyterhub-k8s#3091

UPDATE: verified that deploying 3.0.0-0.dev.git.6175.hf9af31a3 development version works on 1.27.2 k8s version

@minrk Getting this error when spawning singleuser container:

E0531 18:27:29.478156       1 reflector.go:138] k8s.io/client-go/informers/factory.go:134: Failed to watch *v1beta1.CSIStorageCapacity: failed to list *v1beta1.CSIStorageCapacity: the server could not find the requested resource

when deploying jupyterhub helm chart 2.0.0 on k8s version 1.27.2. I see that the has been deprecated in 1.27 (https://kubernetes.io/docs/reference/using-api/deprecation-guide/#csistoragecapacity-v127). Is this expected to be fixed in Jupyterhub 3.0.0? Is there a way I can disable jupyterhub from using CSIStorageCapacity?

@c3-viral-lakhani I think you can do (jupyterhub chart config) scheduling.userScheduler.enabled=False, or use 3.0.0-alpha.1 of the jupyterhub chart.
