Ran:

Quick version:

helm repo add jupyterhub https://jupyterhub.github.io/helm-chart/
helm repo update
kubectl create namespace jhub
kubectl apply -f storage.yaml
# On july 21, 2023, 2.0.0 didn't work, so tried the beta (which worked)
#helm upgrade --cleanup-on-fail --install jhub jupyterhub/jupyterhub --namespace jhub --create-namespace --version=2.0.0 --values config.yaml
helm upgrade --cleanup-on-fail --install jhub jupyterhub/jupyterhub --namespace jhub --create-namespace --version=3.0.0-beta.3 --values config.yaml
kubectl apply -f jhub-ingress.yaml

... but not working. Not sure why.

And the rest are old notes:

  You have successfully installed the official JupyterHub Helm chart!

Installation info

  - Kubernetes namespace: jhub
  - Helm release name:    jhub
  - Helm chart version:   2.0.0
  - JupyterHub version:   3.0.0
  - Hub pod packages:     See https://github.com/jupyterhub/zero-to-jupyterhub-k8s/blob/2.0.0/images/hub/requirements.txt

Followup links

  - Documentation:  https://z2jh.jupyter.org
  - Help forum:     https://discourse.jupyter.org
  - Social chat:    https://gitter.im/jupyterhub/jupyterhub

Post-installation checklist

  - Verify that created Pods enter a Running state:

  kubectl --namespace=jhub get pod

  If a pod is stuck with a Pending or ContainerCreating status, diagnose with:

  kubectl --namespace=jhub describe pod <name of pod>

  If a pod keeps restarting, diagnose with:

  kubectl --namespace=jhub logs --previous <name of pod>

  - Verify an external IP is provided for the k8s Service proxy-public.

  kubectl --namespace=jhub get service proxy-public

  If the external ip remains <pending>, diagnose with:

  kubectl --namespace=jhub describe service proxy-public

  - Verify web based access:

  You have not configured a k8s Ingress resource so you need to access the k8s
  Service proxy-public directly.

  If your computer is outside the k8s cluster, you can port-forward traffic to
  the k8s Service proxy-public with kubectl to access it from your
  computer.

  kubectl --namespace=jhub port-forward service/proxy-public 8080:http

  Try insecure HTTP access: http://localhost:8080
  ```

  Then I did a lot of shit with storage, and it wouldn't let me modify it, so I uninstalled, redid the storage, then reinstalled:

  ```
  helm uninstall jhub jupyterhub/jupyterhub --namespace jhub
  kubectl delete -f storage.yaml
  kubectl -n jhub get pv
  kubectl -n jhub delete pv pvc-1aa270e4-e14f-4425-b10d-e1b18861bb1f
  kubectl apply -f storage.yaml
  ```

  Then reran the apply:

  ```
  $ helm upgrade --cleanup-on-fail --install jhub jupyterhub/jupyterhub --namespace jhub --create-namespace --version=2.0.0 --values config.yaml
