issues shutting down the hub

[lwasser]

@kcranston i'm running into authentication issues when trying to shut down the nbgrader-hub.

i've tried this both in google cloud console and locally and get the same certificate issue. Do you have any idea what this may be about?

i found this but am not sure what this means in terms of implementation

lewa8222@cloudshell:~ (ea-jupyter)$ kubectl get  pods --namespace=nbgrader-hub
Unable to connect to the server: x509: certificate signed by unknown authority

I wonder if your default gcloud / kubectl connection is pointing to the old cluster (jhub) rather than the new cluster (jhub2). That command works for me:

kubectl get  pods --namespace=nbgrader-hub

You may need to regenerate credentials using get-credentials:

gcloud container clusters get-credentials jhub2

ok making progress @kcranston in our docs here

it shows more than the two pods. I see what you printed above which includes 9 lines vs two lines of things running. is this correct?

ALSO helm list doesn't seem to work as it used to. i guess i can wait until you redo the docs as well :)

(base) leahwasser$ helm list
