What this PR does / why we need it:

Reserving resources helps to improve the stability of the cluster components. In my opinion, the resource consumption of the kbelet also changes with the load of the node (Scheduled Pods), so there should also be a possibility to reserve the system resources relative to the node size.

Hi @Payback159. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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/test-infra repository.

Hello @yankay, Hello @mzaian,

I have fixed the variable problem and CI seems to be fine now. May I ask you for a review, maybe the PR will even make it into the v2.25.0 release?

thank you and kind regards! :-)

Hello,

I wanted to drop by here again. Do you have anything against including the PR? 😊

I think it's too late for v2.25 but maybe the PR will make it into the next release. 😁
