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

The blog post announces that the in-place Pod resize feature, introduced as alpha in Kubernetes v1.27, has now graduated to Beta and will be enabled by default in Kubernetes v1.33. This feature allows changing CPU and memory resources for running containers without needing a restart, making resource management more flexible and less disruptive, particularly for stateful applications and batch jobs. The post details the benefits of in-place Pod resizing, such as reduced disruption, improved resource utilization, and faster scaling. It also lists changes since the alpha release, including the introduction of a resize subresource for modifying Pod resources, support for resizing sidecar containers, and various stability and reliability enhancements. Looking ahead, the community plans to continue improving the feature’s stability, integrate it with VerticalPodAutoscaler (VPA), and gather user feedback to prioritize future enhancements. Users are encouraged to experiment with the feature and provide feedback through Kubernetes communication channels. 👉 Read more
