Singleuser won't use any images except the default

JupyterHub Zero to JupyterHub on Kubernetes
1

Hi.

I’m getting a problem with my Jupyterhub deployment on k8s. No matter what image I’ve supplied it, it still boots up the default single image server.

Here is my config.yaml file:

proxy:
  secretToken: <some_token>
singleuser:
  image:
    name: jupyter/datascience-notebook
    tag: latest
#    pullSecrets:
#    - "regcred"
hub:
  config:
    Authenticator:
      admin_users:
        - <ome_users>
      allowed_users:
        - <some_users>
    GitHubOAuthenticator:
      client_id: "<some_id>"
      client_secret: "<some_secret>"
      oauth_callback_url: "<my_url>/hub/oauth_callback"
    JupyterHub:
      authenticator_class: github

However, when I update the hub with

helm upgrade --cleanup-on-fail \
--install jhub jupyterhub/jupyterhub   \
--namespace=jhub  \
--version=0.11.1  \
--values config.yaml

The subsequent singleuser sessions don’t have any of the datascience’s packages installed. If I instead uncomment the pullSecrets and use my own docker image as in the tutorial:

FROM jupyter/datascience-notebook:latest

# create a user, since we don't want to run as root
ARG JUPYTERHUB_VERSION=1.3.0
RUN pip3 install --no-cache \
    jupyterhub==$JUPYTERHUB_VERSION

CMD ["jupyterhub-singleuser"]

The same problem persists. When I launch these pods outside of jupyterhub and inspect the installed conda environment, I’ve found that they contain the packages. So jupyterhub has a bug that is preventing it from using jupyter/datascience-notebook:latest image or else I have donfigured something wrong. Advice is appreciated. Thanks.
