Hi,
I’ve just open-sourced a new tool that is midway between Kubeflow’s notebooks and JupyterHub on Kubernetes notebooks, to deploy and manage notebooks on Kubernetes.
I want it to be simple and to take advantage of already existing Kubernetes ecosystem features (authn/authz, Helm, ingress-nginx, Horizontal autoscaler etc.).
Learn more about it at GitHub - machine424/notebook-on-kube: Create and manage your Notebooks on Kube using bare minimum code.. Give it a try and let me know 
Cheers,
