Hi @nickstern2002. 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.

enable scale from zero in Coreweave cluster autoscaler

(sorry for the nitpicky release notes, but we have a lot of projects and providers in the monorepo and concision is easier for disambiguation)

[jackfrancis]

@ddymko @keedya are you willing to sign up as Kubernetes members? See:

• https://github.com/kubernetes/community/blob/master/community-membership.md#requirements

If not, we should probably have a plan to remove you from the official OWNERS file.

In the meantime if you could give @nickstern2002's PRs a review that would be great, I can land them if they look good from the coreweave side of things.

[ddymko]

@jackfrancis yeah totally open to it!

I'll also take a look at @nickstern2002 PR

@nickstern2002 @keedya @ddymko would you like this in the 1.34 branch for best results on k8s 1.34 clusters, or is this sufficient to wait for the 1.35 release of CA (and the guidance would be that for best results you should only run w/ a k8s 1.35 cluster)?

@jackfrancis if possible, could this be included in the 1.34 branch please?
