Facing connection refused issue due to unavailability of opendatahub/jovyan/api while testing jupyter-minimal-ubi8-python-3.8 notebook image on Power

[someshmlad]

We have built the jupyter-minimal-ubi8-python-3.8 notebook image on Power(ppc64le), the make deploy command for this notebook image is working fine and the pods are up and running:

# oc get all

But while performing make test for the same notebook, we are getting the following issue:

# make test-jupyter-minimal-ubi8-python-3.8
# Running tests for jupyter-minimal-ubi8-python-3-8 notebook...
bin/kubectl wait --for=condition=ready pod -l app=jupyter-minimal-ubi8-python-3-8 --timeout=600s

exit ${EXIT_CODE}
curl: (7) Failed to connect to localhost port 8888: Connection refused

make: *** [Makefile:289: test-jupyter-minimal-ubi8-python-3.8] Error 7

Any suggestions on how we can resolve the following issue would be helpful. Also, if anyone could provide some reference doc or source repo for jovyan/api, that would be helpful. Thanks

@someshmlad Thanks for opening the issue. We are working on gathering resources for powerpc testing. I'll reach out to you soon.

if possible, can you share if you are able to set a route for the service and test the notebook from there ?

Also some information, the notebook are kept in standard of kubeflow notebooks, so they function as required on notebook controller. https://www.kubeflow.org/docs/components/notebooks/container-images/#image-requirements
