In-place pod vertical scaling

Question

In-place pod vertical scaling

Doroftei Andrei 0

I want to have an estimate on when the feature gate used for the In-place pod vertical scaling will be enabled in AKS. It reached Beta and it's enabled by default. I would really benefit from this feature. I couldn't find anything related in the Roadmap.

Hi @Durga Reshma Malthi !
Yes, I've seen it. Thanks a lot for the info.

Maybe I'm wrong, but in the link I've provided, the feature is stated as Beta, not Alpha.

Edit:

I also found this: https://kubernetes.io/docs/tasks/configure-pod-container/resize-container-resources/

We would use it to give more CPU to Spring Applications at startup and lower it afterwards. We wanted to leverage https://github.com/google/kube-startup-cpu-boost

End Edit.

Could you "estimate" when it will become available on AKS? (days, weeks, months, years, etc)

I am really excited about this feature. That's why I am so eager to use it. :D

Answer 1

Hi Doroftei Andrei

The in-place pod vertical scaling feature is managed through a feature gate, and its availability depends on both the Kubernetes version supported by AKS and the feature's stability for production workloads.

In-Place Vertical Pod Scaling was introduced in Kubernetes 1.27, allowing for dynamic adjustments of CPU and memory resources without recreating pods. However, this feature is still in its alpha stage and requires a feature gate to be enabled before use.

At this time, there is no official release time for when specific feature gates like in-place pod vertical scaling will be enabled, as Microsoft and the Kubernetes community typically release features gradually, following extensive testing and a stable rollout process.

To stay updated on its progress:

Monitor Microsoft Learn and AKS documentation for future announcements.
Follow ongoing discussions and testing efforts on GitHub: https://github.com/kubernetes/autoscaler/issues/4016 https://github.com/kubernetes/autoscaler/pull/7673

Hope this helps!

Please Let me know if you have any queries.

Answer 2

Hi Doroftei Andrei

You're absolutely right—the feature is in Beta, not Alpha. Thanks for pointing that out!

Regarding the estimate for when In-place pod vertical scaling will be fully available in Azure Kubernetes Service (AKS), Microsoft hasn't announced a GA (General Availability) date yet. However, based on typical Kubernetes feature rollouts, here’s a rough estimate:

Beta Stage (Current) – The feature is enabled by default and is being tested at scale.
GA Timeline – If Microsoft follows standard Kubernetes release cycles, many Beta features transition to GA within 3–6 months, but this depends on stability, adoption, and feedback.
Monitoring Updates – The best way to track progress is through Azure Kubernetes Service release notes and Microsoft's AKS documentation for official updates.

We expect full AKS support by mid-to-late 2025, depending on testing and rollout.

Hi Doroftei Andrei,

Thanks for letting know that in-place pod auto scaling is available with AKS 1.33.00

We are also planning to use that feature in our project. Can you mention that how did you test this feature on your cluster.

Thanks.

Hi Nawagamuwa Thulitha,

We've used https://github.com/google/kube-startup-cpu-boost to remove the very high CPU limits from our JVM containers.
