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 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, 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

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