🔹 Kubernetes - Kubernetes v1.33: Mutable CSI Node Allocatable Count

The blog post discusses a new alpha feature in Kubernetes v1.33 called “mutable CSI node allocatable count,” which enhances the scheduling of stateful applications by allowing Container Storage Interface (CSI) drivers to dynamically update the maximum number of volumes a node can handle. Traditionally, CSI drivers report static volume limits, which can lead to scheduling issues when actual capacities change. The new feature allows for more accurate pod scheduling by supporting periodic and reactive updates to node capacity information. To enable this feature, the MutableCSINodeAllocatableCount feature gate must be activated in the kube-apiserver and kubelet components, and CSI drivers configured accordingly. This feature aims to reduce scheduling failures and improve cluster health by ensuring up-to-date resource availability information. Users are encouraged to test the feature and provide feedback to help guide its development. 👉 Read more
