kubernetes jupyterhub HUB_CONNECT_IP

[Paul Mazzuca]

I am trying to get JupyterHub to work in Kubernetes by starting with MiniKube.  I have authentication working but am unable to spawn using the kubespawner.  I believe my issue is the HUB_CONNECT_IP env variable that I am using.

What exactly should this value be?  I am using a nodeport service with the following ip/port

jupyter-hub-service   10.0.0.161   <nodes>       8000:31176/TCP

Minikube has the dns add on, but am I still supposed to set HUB_CONNECT_IP to an IP?  Given that my nodeport service is as above, anyone have any guidance on what HUB_CONNECT_IP should be, or is there some other action that should be taken?

Take a look at https://github.com/jupyterhub/kubespawner/blob/master/SETUP.md which has a nice method for doing dev work on minikube.

Great thanks!  How about in the case that I were running this in production, and not on minikube? What should that HUB_CONNECT_IP be, given the same nodeport?

If you're running this in production, I'd recommend using
http://z2jh.jupyter.org/ which documents how to use our helm chart to
run on any k8s cluster.

If you wanna see how it does it, look at
https://github.com/jupyterhub/helm-chart/blob/master/images/hub/jupyterhub_config.py#L138.
We don't use node port at all - the hub runs inside the k8s cluster as
well and spawns the pods in there, and just uses the service IPs as
HUB_IP_CONNECT...
