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

The tech blog post announces the graduation of the “in-place Pod resize” feature in Kubernetes to Beta status, starting from version 1.33. This feature, also known as In-Place Pod Vertical Scaling, allows for the adjustment of CPU and memory resources for running Pods without requiring restarts, reducing disruption for stateful applications and enhancing resource utilization. Key updates include the introduction of a “resize” subresource for modifying Pod resources, better status tracking through Pod conditions, and support for resizing sidecar containers. The feature has undergone significant improvements since its alpha version, enhancing stability, reliability, and efficiency. Future development will focus on stability, addressing limitations, integrating with VerticalPodAutoscaler, and gathering user feedback. The feature is enabled by default in Kubernetes v1.33, and users are encouraged to experiment with it and provide feedback. 👉 Read more
