k8s: Kubernetes v1.35: Mutable PersistentVolume Node Affinity (alpha)

Kubernetes Official Blog

2026-01-08

Kubernetes v1.35 (alpha) makes PersistentVolume.spec.nodeAffinity mutable. This allows administrators to update PV node affinity to match changes in underlying storage (for example zonal→regional migrations or disk-generation upgrades) without recreating the PV. The feature is gated (MutablePVNodeAffinity), disabled by default, and requires updating the storage provider first. Be aware of scheduling race conditions when tightening affinity; future kubelet/CSI integration and VolumeAttributesClass automation are planned. Feedback is requested via SIG Storage channels.

k8s: Kubernetes v1.35: Watch Based Route Reconciliation in the Cloud Controller Manager

Kubernetes Official Blog

2025-12-30

Kubernetes v1.35 introduces an alpha feature gate (CloudControllerManagerWatchBasedRoutesReconciliation) in k8s.io/cloud-provider that changes the CCM route controller from a fixed-interval reconciliation to a watch/informer-based trigger model. The change reduces unnecessary cloud API calls by reconciling routes only when relevant node or CIDR/address fields change, with an additional randomized periodic reconcile every 12–24 hours. The reconciliation logic itself is unchanged and the feature is enabled via --feature-gate.

k8s: Kubernetes v1.34: Pod Level Resources Graduated to Beta

Kubernetes Official Blog

2025-09-22

Kubernetes v1.34 graduates Pod Level Resources to Beta and enables it by default. The feature lets you declare CPU, memory and hugepages for an entire Pod (in addition to per-container settings), with pod-level requests used for scheduling and pod-level limits acting as an absolute runtime cap; it improves intra-pod sharing and QoS handling but has several platform and feature limitations.

k8s: Kubernetes v1.34: DRA Consumable Capacity

Kubernetes Official Blog

2025-09-18

Kubernetes v1.34 introduces the alpha feature DRAConsumableCapacity for Dynamic Resource Allocation (DRA). It enables finer-grained, consumable device capacity so multiple ResourceClaims or DeviceRequests (even across namespaces) can share portions of a device. The scheduler enforces total consumable capacity, drivers can opt into multiple allocations and define request policies, and a ShareID in allocation status distinguishes individual shared slices. The feature requires enabling a feature gate on control plane and kubelet components and complements other DRA improvements like partitionable devices and device status.
