I'm trying to simplify main.go files but this would better be taking baby steps.

this very first step is to try to clean up spec.

Hi @jimexist. Thanks for your PR.

I'm waiting for a kubernetes or tensorflow 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.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Would be nice to update the PR description with a bit more detail.

LGTM but the pre-submit failed.

Please sync so that we rerun the tests using Argo. The presubmits should be much easier to debug if needed since logs should be publicly accessible via the Argo UI.

@jimexist Any chance you could sync? Would be great to get this committed?

[jimexist]

@jlewi haven't been following closely recently, any docs on running Argo e2e test and ksonnet?

The tests are triggered automatically and they ran successfully.
