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

The blog post announces that the in-place Pod resize feature, initially introduced as an alpha feature in Kubernetes v1.27, has been promoted to Beta and will be enabled by default starting with Kubernetes v1.33. This feature allows users to adjust CPU and memory resources for running Pods without requiring a restart, which is particularly beneficial for stateful applications, long-running batch jobs, and workloads sensitive to restarts. The in-place Pod resize offers reduced disruption, improved resource utilization, and faster scaling. Key changes from alpha to beta include the introduction of a resize subresource for modifying Pod resources, new conditions for reporting resize status, and support for resizing sidecar containers. Enhancements have been made to improve stability, reliability, and performance. The Kubernetes community will continue to focus on hardening the feature, addressing current limitations, and integrating with the VerticalPodAutoscaler. Users are encouraged to provide feedback as the feature progresses through Beta. 👉 Read more
