🔹 Kubernetes - Kubernetes v1.33: In-Place Pod Resize Graduated to Beta

The blog post announces that the in-place Pod resize feature, also known as In-Place Pod Vertical Scaling, has progressed to Beta status and is enabled by default in Kubernetes v1.33. This feature allows CPU and memory resources of running Pods to be adjusted without requiring a restart, reducing disruption for stateful applications and improving resource utilization. Notable updates from its alpha version include the introduction of a “resize” subresource for modifying resources, status conditions indicating resize progress, and support for sidecar containers. Enhancements in stability, reliability, and faster resize detection have been made, along with numerous bug fixes. The community is focusing on further improving the feature, addressing limitations, integrating with VerticalPodAutoscaler, and gathering user feedback. The post encourages users to experiment with the feature and provide feedback through official Kubernetes channels. 👉 Read more
