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: Extended Toleration Operators to Support Numeric Comparisons (Alpha)

Kubernetes Official Blog

2026-01-05

Kubernetes v1.35 introduces Extended Toleration Operators (alpha) that add numeric comparison operators Gt and Lt to spec.tolerations. This lets tolerations compare numeric taint values (e.g., failure-probability, gpu-compute-score, disk-iops, cost-per-hour) so schedulers can make threshold-based placement decisions while preserving taint/toleration semantics (centralized node-side policy and eviction via NoExecute). The feature is gated, supports all taint effects, has specific numeric format rules, and is experimental — feedback and further enhancements (CEL, autoscaling integration, graduation) are planned.

k8s: Kubernetes v1.35: New level of efficiency with in-place Pod restart

Kubernetes Official Blog

2026-01-02

Kubernetes v1.35 introduces an alpha feature, Restart All Containers (enabled with the RestartAllContainersOnContainerExits feature gate), which adds a RestartAllContainers action to container restart rules to perform a fast, in-place full Pod restart that preserves Pod UID, IP, sandbox and volumes while re-running init, sidecar and application containers.

k8s: Announcing Changed Block Tracking API support (alpha)

Kubernetes Official Blog

2025-09-25

Kubernetes announces alpha support for a Changed Block Tracking API that lets CSI drivers report allocated and changed blocks between snapshots to enable faster, incremental backups for block volumes. The feature requires a SnapshotMetadataService CRD, an external-snapshot-metadata sidecar, and CSI SnapshotMetadata gRPC RPCs (GetMetadataAllocated and GetMetadataDelta) with streaming responses.

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.
