See the "Kubernetes on NVIDIA DGX Servers User Guide" for Kubernetes usage examples:

Jupyterhub

https://github.com/jupyterhub/jupyterhub

With JupyterHub you can create a multi-user Hub which spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server.

Project Jupyter created JupyterHub to support many users. The Hub can offer notebook servers to a class of students, a corporate data science workgroup, a scientific research project, or a high performance computing group.

Label nodes where you want the notebook pods to run:

kubectl label nodes dgx01 gpu=true

Modify config/jupyterhub-config.yml if needed and deploy with Helm:

kubectl create ns jh
helm repo add jupyterhub https://jupyterhub.github.io/helm-chart/
helm repo update
helm install jupyterhub/jupyterhub --name=jupyterhub --namespace=jh -f config/jupyterhub-config.yaml --set prePuller.enabled=false

Remove:

helm del --purge jupyterhub

You may have to install/delete/re-install if there are RBAC errors. You can also try deleting the proxy pod so it's re-created

If you make changes to the config file:

helm upgrade jupyterhub jupyterhub/jupyterhub --version=v0.6 -f config/jupyterhub-config.yaml
