We want kubetest2-kops to dynamically create a temporary s3 bucket when the presubmit is running, similar to this code
https://github.com/kubernetes/kops/blob/master/tests/e2e/kubetest2-kops/gce/gcs.go

I made the IAM changes, but it allows presubmits to write to our CI bucket which isn't ideal(existing behaviour we should change).

Yes I see the migrated job on your PR passed, using k8s-staging-kops:

https://prow.k8s.io/view/gs/kubernetes-jenkins/pr-logs/pull/kops/16648/pull-kops-e2e-k8s-aws-calico-k8s-infra/1809653969442574336

I believe this means we could migrate all presubmit jobs to use this, but you're right giving presubmit jobs write permissions to the same bucket used for post-merge artifacts like version markers is not great.

We have the k8s-infra-kops-ci-results bucket created in kubernetes/k8s.io#2678, is that in the correct project and can we use it for either presubmit artifacts or version markers, and then revoke permissions for presubmits to whichever bucket we choose for version markers?

For now, let's retain the existing behaviour as AWS presubmits have been writing to the k8s-staging-kops bucket and let's try to switch to dynamic buckets on AWS.

As for gs://k8s-infra-kops-ci-results, I don't want to use this bucket and we should delete it.

We do also have hack/upload, which might make this easier?

cmd.SetDir(b.KopsRoot)
exec.InheritOutput(cmd)
if err := cmd.Run(); err != nil {
return nil, err
}

// Get the full path (including subdirectory) that we uploaded to

It might be nice to spell out the two tasks here (assuming we can't combine them), to make it more explicit and to help with searching...

This actually LGTM. We're probably holding this PR for now (given that the test-infra one is closed), but I think a good reason to upload artifacts to S3 would be to cut down on bandwidth etc costs for testing. But I guess they aren't that large....

We do need to ship this to fix the AWS presubmits publishing to the k8s-staging-kops bucket. We carried over that practice when the jobs were migrated to the community cluster.
