Docker image selection dropdown not rendering

[jgerardsimcock]

I am running a deployment that is based on the "v0.7-4c22c3d " jupyterhub helm-chart. I am trying to add additional docker images to my notebook for my users following the merge of #137 . From my understanding, I just add c.KubeSpawner.profile_list to the extraConfig and specify the images I want to use? Am I missing anything?

hub:
    extraConfig: |
      from kubernetes import client
      def modify_pod_hook(spawner, pod):
          pod.spec.containers[0].security_context = client.V1SecurityContext(
              privileged=True,
              capabilities=client.V1Capabilities(
                  add=['SYS_ADMIN']
              )
          )
          return pod
      c.KubeSpawner.modify_pod_hook = modify_pod_hook
      c.JupyterHub.logo_file = '/usr/local/share/jupyter/hub/static/custom/images/logo.png'
      c.JupyterHub.template_paths = ['/usr/local/share/jupyter/hub/custom_templates/',
                                    '/usr/local/share/jupyter/hub/templates/']

      c.KubeSpawner.profile_list = [
        {
        'display_name': 'Dask-Hub - Python',
        'kubespawner_override': {
            'singleuser_image_spec': 'rhodium/notebook:2018-04-17',
        }
        },
        {   
        'display_name': 'R Notebook',
        'kubespawner_override': {
            'singleuser_image_spec': 'civisanalytics/datascience-r:latest',
        }
        }
        ]

Did you update the kubespawner rev listed in z2jh's images/hub/requirements.txt?

Thank you @clkao

after adding the requirements.txt file we'll also need to update our Dockerfile with the lines below and then redeploy our helm chart:

ARG JUPYTERHUB_VERSION=0.8.*

ADD requirements.txt /tmp/requirements.txt
RUN pip3 install --no-cache-dir \
         jupyterhub==${JUPYTERHUB_VERSION} \
         -r /tmp/requirements.txt

Do I understand this right?
