When running the Krkn Scenario, they run inside container environment (like podman or docker). In that case, if the kubeconfig.yaml used for testing has reference to ca.crt instead of direct embedding, then I guess we will run into this issue.

When I was trying out the minikube setup on my system I was able to generate one with this command:

kubectl config view \
  --context=minikube \
  --minify \
  --flatten \
  --raw > kubeconfig.yaml

Also captured this in documentation here.

Hi @rh-rahulshetty , I’ve submitted a PR addressing this issue #197. Whenever you get a chance, I’d appreciate your review and feedback.
