@riendeau is like that, but then there are 2 additional steps

1. make the changes
2. promote the image that has been built with the postsubmit job
3. update the repo to use the new image

More detail in https://github.com/kubernetes/kubernetes/tree/master/test/images#promoting-images

If you want to try, please make sure you are going to follow up with all the steps, you can see other promotions PRs too #123655

@aojea Thank you for this information! Is the manual building and testing of images described in that same document something that you would consider a prerequisite for a proposed change like this? Or is it safe to assume that the automated PR test bucket(s) would provide sufficient test coverage?
