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

The blog post announces the graduation of the Pod Level Resources feature to Beta in Kubernetes v1.34, where it is now enabled by default. This feature offers a new level of flexibility by allowing CPU and memory resources to be specified at the Pod level, rather than just at the container level. This approach simplifies resource management by reducing the need for per-container resource specifications, especially in multi-container Pods. It also allows for more efficient resource sharing within Pods, preventing performance bottlenecks from sidecar containers. Pod-level resource requests and limits take precedence over container-level specifications, providing a consolidated method for enforcing resource boundaries and influencing Quality of Service (QoS) classes. The feature is designed to integrate smoothly with existing Kubernetes functionalities, though it does not support in-place resizing for running Pods or apply to Windows Pods. Users are encouraged to provide feedback as the feature progresses through its Beta phase. 👉 Read more
