I want to deploy my own image on JuPyter-hub. However, I need to deploy it to some registry so that the image puller of JHub can pull it from there. In my case, the registry is private. Although I am able to push the image to my registry, I don't know how will I make the jupyterhub release and deployment be able to pull the image.

I tried reading this doc (https://github.com/jupyterhub/jupyterhub-deploy-docker) but it could not help me understand how am I to add authentication in the jupyter hub deployment.

I deploy jhub with this command:

#  Suggested values: advanced users of Kubernetes and Helm should feel
# free to use different values.
RELEASE=jhub
NAMESPACE=jhub

helm upgrade --install $RELEASE jupyterhub/jupyterhub \
  --namespace $NAMESPACE  \
  --version=0.8.0 \
  --values jupyter-hub-config.yaml

where the jupyter-hub-config.yaml is as follows:

proxy:
  secretToken: "abcd"
singleuser:
  image:
    name: jupyter/datascience-notebook
    tag: some_tag
  lifecycleHooks:
    postStart:
      exec:
        command: ["/bin/sh", "-c", 'ipython profile create; cd ~/.ipython/profile_default/startup; echo ''run_id = "sample" ''> aviral.py']

The helm chart is available here: https://jupyterhub.github.io/helm-chart/jupyterhub-0.8.2.tgz

And the tree of this helm chart is:

All I want to do is to make jupyterhub access my private repo using secrets. In this case, I do not know how to make this available to it.
