Error: module 'kubernetes.client' has no attribute 'V1Subject'

When I use the 3.2.3 image, I encountered this error when spawning a kernel:

[I 2024-05-31 08:44:21.065 EnterpriseGatewayApp] Created kernel namespace: jovyan-b4ca16d6-eb9f-431e-abef-e4f5ac9b344d

using the server image: jupyter/base-notebook:python-3.9.7

Greetings! I ran into the same problem today. The fastest way to solve it for me was to build a new container with minimal changes:

FROM elyra/enterprise-gateway:3.2.3

USER root

RUN sed -i 's/V1Subject/RbacV1Subject/g' /opt/conda/lib/python3.10/site-packages/enterprise_gateway/services/processproxies/k8s.py

USER jovyan

As you can see the problem is in the line.

enterprise_gateway/enterprise_gateway/services/processproxies/k8s.py

Line 352 in d01e84a

binding_subjects = client.V1Subject(

It uses V1Subject, which is not supported by kubernetes library version 29

I have also created a pull request that should solve this problem - #1384

I hope this issue gets fixed soon. Just change V1Subject to RbacV1Subject.
