Hi @ScorpioCPH. 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.

Looks good. Just waiting to see if the tests pass.

[ScorpioCPH]

@jlewi Sorry, tf-k8s-presubmit failed, but i can't see the err logs.

Here are the logs

I don't actually see the build/ dir in the repo so I think the files build/images/... are actually missing from the PR. Looks like build/ is ignored by .gitignore.

[jlewi]

I was looking around to see what other projects do.
prow has in images directory in prow/cmd.

I actually like that as it means the image leaves close to the directory. Could we do the same thing and
move build/images/tf_operator/Dockerfile -> pkg/cmd/images/tf_operator
?

[ScorpioCPH]

@jlewi Maybe it's a little weird putting some Dockerfiles in cmd, and pkg is directory for library in golang, i think there is no pkg/cmd sub directory.

Like kuberneres repo, there is a build directory for Dockerfiles. I will take a look at gitignore.

And another thing: can we attach the building logs in the details link? so PR author can debug the building errors.

[jlewi]

I don't feel too strongly about the location. If you think build is best I can live with that.

Short answer is the test infrastructure is a pain point and its something I plan on fixing.

• We will copy logs to Gubernator
• We will open up the Argo UI

But this is blocked on migrating off Airflow to Argo. Its not worth fixing with Airflow since I want to get rid of Airflow.

@jlewi Hi, is there any thing i can help about e2e stuff? I'm happy to take a look at this :)

We need to get #293 fixed before we can trust the tests again.

@jlewi Tests passed, PTAL, thanks!

[jlewi]

Tests did not pass. Due to #315 you need to actually click on the details for tf-k8s-presubmit. There you see there is 1 test failure which should be fixed by #308.

[jlewi]

Head should be fixed. Can you sync and push so the tests rerun?
