Hi @roytman. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Thanks @roytman, the tests are passed now. Are you planning to refactor the two for loops for configmap mount and configmap env into functions?

Hi @Tomcli , sorry, I don't see how it can be done without changes in kubernetes_platform/proto/kubernetes_executor_config.proto and in k8s.io/api/core/v1 can we check it together?

I'm thinking more of refactoring the common pieces between configmap and secret volume mount into a common function. Since it involved some object abstraction for configmapRef/secretRef, we can defer this to a follow up PR.
