Hi @prad9192. Thanks for your PR.

I'm waiting for a github.com 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.

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-sigs/prow repository.

@prad9192: Cannot trigger testing until a trusted user reviews the PR and leaves an /ok-to-test message.

Prow isn't built here anymore, I'm not sure if we should just be deleting these images now.

If your goal is to patch prow, this may not be the solution. see sigs.k8s.io/prow

Hi @BenTheElder

Thanks for your review, I see that Prow depends on base images which are sourced from this repo.

PR updates the source Dockerfiles that build k8s-staging-test-infra/* images, which are still built and pushed through the post submit jobs here - https://github.com/kubernetes/test-infra/blob/master/config/jobs/image-pushing/k8s-staging-test-infra.yaml

And having these updated images would allow me to open a follow up PR to make updates to base images referenced in prow

/hold

We should merge #35799 and create an autobumper config in the prow repo to pick up the new images automaticall.y

Thanks for your review, I see that Prow depends on base images which are sourced from this repo.

ACK ... that's been messy since prow was split out of this repo :-)

In most cases prow does not depend on this repo anymore, and shouldn't

For the images only used by prow, we should probably move them for clarity, but it's not important. This directory is highly overloaded and the other images have other considerations ...
