Kubernetes v1.36 introduces In-Place Pod-Level Resources Vertical Scaling, now in Beta and enabled by default. This feature allows users to dynamically adjust the aggregate resource limits of a running Pod. This is particularly useful for Pods with shared resources and no container-specific limits. The Kubelet determines the update method based on each container's `resizePolicy`, deciding between in-place updates or restarts. When a resize happens, the Kubelet first checks if the node has enough resources. It then sequences cgroup updates to prevent resource overshoot, expanding the pod-level cgroup before individual container cgroups are enlarged. Pod conditions, like `PodResizeInProgress`, track the resize's progress and status. The feature requires cgroup v2, CRI support, specific feature gates, and Linux-based nodes. The next step is integrating this with the Vertical Pod Autoscaler (VPA). Users are encouraged to test this feature and provide feedback through the community channels.
