Does K8s support in-place autoscaling, which means update cpu resource on the fly. I want to change the cpu utilization of a pod without any termination(restarting or evcting).

I have look for this anwser for a long time. I see that the [enhancement](https://github.com/kubernetes/kubernetes/pull/102884) in K8s menting it is achieved in K8s, but when I asked this issue in slack of `sig-autoscaling`, they told me it is not achieved now as in the [PR](https://github.com/kubernetes/enhancements/issues/1287), and it waits for other components(like kubelet or CRI) to supports auto-scaling on the fly.

Now I can’t tell whether K8s supports in-place autoscaling or not. Who can tell me the exact answer？  
Thanks a lot!

It’ll be alpha in 1.27 (the release slated for next month). Details are here: [In-Place Update of Pod Resources · Issue #1287 · kubernetes/enhancements · GitHub](https://github.com/kubernetes/enhancements/issues/1287)

Thanks!  
Now, I think the K8s supports the in-place vertical scaling without termination!
