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

The blog post announces that the “in-place Pod resize” feature, introduced as an alpha feature in Kubernetes v1.27, has graduated to Beta and is enabled by default in Kubernetes v1.33. This feature allows CPU and memory resources for running Pods to be adjusted without requiring a restart, which is beneficial for stateful applications and workloads sensitive to disruptions. Key changes from alpha to beta include the introduction of a “resize” subresource, improved resource management, and sidecar support. The feature enhances resource utilization, reduces disruption, and accelerates scaling. Moving forward, the community plans to enhance the feature’s stability, address limitations, integrate it with the VerticalPodAutoscaler (VPA), and gather user feedback. Users are encouraged to experiment with the feature and provide feedback through Kubernetes communication channels. 👉 Read more
