🔹 Kubernetes - Kubernetes v1.34: Pod Level Resources Graduated to Beta

The blog post announces that the Pod Level Resources feature in Kubernetes has reached Beta status with the release of Kubernetes v1.34 and is enabled by default. This feature allows for specifying CPU and memory resources at the Pod level, providing a new layer of flexibility in resource management. It simplifies resource allocation by reducing the need for granular per-container specifications, promoting efficient resource sharing within Pods, and preventing performance bottlenecks caused by sidecar containers. Pod-level requests and limits take precedence over container-level specifications, ensuring a robust way to enforce resource boundaries. Additionally, this feature affects Quality of Service (QoS) class determination and Out-Of-Memory (OOM) score adjustments. The post includes examples of how to specify resources for Pods and discusses the feature’s limitations, such as the lack of support for in-place resizing and Windows Pods. It encourages users to provide feedback as the feature progresses through its Beta phase. 👉 Read more
