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

The blog post announces the graduation of the “in-place Pod resize” feature to Beta in Kubernetes v1.33, which allows for changes to CPU and memory resources of a running Pod without requiring a restart. This feature, first introduced as alpha in v1.27, enhances resource management by reducing disruption and improving resource utilization. Key changes from the alpha stage include a new resize subresource to modify Pod resources, a revised status reporting system, and support for sidecar containers. Enhancements have been made for stability and reliability, including refined resource management and improved resize detection. The community aims to further stabilize the feature, integrate it with VerticalPodAutoscaler, and gather user feedback for future improvements. Users can start experimenting with this feature in v1.33 and are encouraged to provide feedback via Kubernetes communication channels. 👉 Read more
