500 Error Jupyter notebook

[kstory8]

I tried to launch a jupyter notebook from a custom docker image. This failed (presumably because of permissions issues accessing the particular GCR). Now, jupyterhub keeps failing with the following error:

500 : Internal Server Error
Failed to reach your server. Please try again later. Contact admin if the issue persists.

You can try restarting your server from the home page.

instructions on customizing jupyterhub and notebook images:
https://github.com/kubeflow/kubeflow/tree/master/components/jupyterhub
https://github.com/kubeflow/kubeflow/tree/master/components/jupyterhub#notebook-image

If you've already followed the instructions on the above link to create notebook images, create a secret with the credentials and add it to the jupyterhub serviceaccount:
kubectl patch -n kubeflow serviceaccount jupyter -p '{"imagePullSecrets": [{"name": "secretname"}]}'

@jlewi Can you offer more instructions or the user practice to customize notebook images?

Can you provide the full JupyterHub logs?
I would also suggest deleting the JupyterHub pod to force it to restart.
You can also check for any jupyter pods and delete those.
