🔹 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 status in Kubernetes v1.33, where it will be enabled by default.

The update includes several enhancements since its alpha release, such as a new resize subresource for modifications, improved resource management, sidecar support, and better integration with the Container Runtime Interface (CRI). Looking ahead, the Kubernetes community plans to focus on further stabilizing the feature, integrating it with the VerticalPodAutoscaler (VPA), and gathering user feedback. Users can start experimenting with this feature and provide feedback through standard Kubernetes communication channels. 👉 Read more
