k8s: Ingress NGINX Retirement: What You Need to Know

Kubernetes Official Blog

2025-11-11

Kubernetes SIG Network and the Security Response Committee announced the retirement of Ingress NGINX. Best-effort maintenance will continue until March 2026; after that there will be no further releases, bug fixes, or security updates. Users are advised to migrate to Gateway API or another Ingress controller.

k8s: Announcing the 2025 Steering Committee Election Results

Kubernetes Official Blog

2025-11-09

The 2025 Kubernetes Steering Committee election concluded. Four of seven seats were up for election; the incoming members begin two-year terms immediately. The post announces the newly elected members, continuing members, election officers, emeritus members, and gives ways for the community to follow and participate in Steering Committee work.

k8s: Gateway API 1.4: New Features

Kubernetes Official Blog

2025-11-06

Gateway API v1.4.0 (released Oct 6, 2025) advances Kubernetes service networking with three features promoted to Standard (BackendTLSPolicy, supportedFeatures in GatewayClass status, and named rule fields for Routes) and several experimental additions (Mesh/XMesh, default Gateways, and an ExternalAuth filter for HTTPRoute). The release also adds per-port TLS/client-certificate configuration to address connection coalescing security, introduces a couple of breaking validation changes, improves CI/docs, and is usable on Kubernetes >=1.26.

k8s: 7 Common Kubernetes Pitfalls (and How I Learned to Avoid Them)

Kubernetes Official Blog

2025-10-20

The article outlines seven common Kubernetes pitfalls the author encountered—missing resource requests/limits, inadequate liveness/readiness probes, overreliance on kubectl logs, treating dev and prod identically, leaving stale resources, jumping into advanced networking too early, and weak security/RBAC—and gives pragmatic, experience-based advice to avoid each one.

k8s: Spotlight on Policy Working Group

Kubernetes Official Blog

2025-10-18

The Policy Working Group (now completed) worked to standardize and simplify policy management across the Kubernetes ecosystem. Led by co-chairs Jim Bugwadia, Poonam Lamba, and Andy Suderman, the group produced documentation, whitepapers, a CNCF survey, and the Policy Reports API, and helped educate the community about built-in policy APIs and CNCF policy tools. The WG coordinated with SIG Auth and SIG Security, faced contributor-time and consensus challenges, and encouraged newcomers to join meetings and review materials to get involved.

k8s: Introducing Headlamp Plugin for Karpenter - Scaling and Visibility

Kubernetes Official Blog

2025-10-06

The Headlamp Karpenter Plugin integrates Karpenter autoscaling visibility into the Headlamp Kubernetes UI, providing real‑time maps, metrics, scaling decisions, pending‑pod diagnostics, and an editable, validated config editor to help users understand, debug, and tune node provisioning and autoscaling behavior.

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: 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: Recovery From Volume Expansion Failure (GA)

Kubernetes Official Blog

2025-09-19

Kubernetes v1.34 graduates automated recovery from failed persistent volume expansions to GA. Users can correct an over-sized PersistentVolumeClaim (PVC) by reducing the requested size (as long as the new request is still larger than the PV's original capacity) without cluster-admin intervention; consumed quota from a failed expansion is returned automatically. The release also introduces improved observability and error reporting for expansion operations, retries with reduced request rates, and several resizing workflow bug fixes.

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.

k8s: Kubernetes v1.34: Pods Report DRA Resource Health

Kubernetes Official Blog

2025-09-17

Kubernetes v1.34 introduces an alpha feature (ResourceHealthStatus) that lets Dynamic Resource Allocation (DRA) drivers report device health into a Pod's status via a new dra-health/v1alpha1 gRPC service, enabling the Kubelet to surface per-device health in v1.ContainerStatus. This improves debuggability for hardware-backed workloads by showing device health (Healthy/Unhealthy/Unknown) in allocatedResourcesStatus and requires enabling the feature gate and compatible DRA drivers.

k8s: Kubernetes v1.34: Moving Volume Group Snapshots to v1beta2

Kubernetes Official Blog

2025-09-16

Kubernetes v1.34 advances Volume Group Snapshots to v1beta2. The update adds a VolumeSnapshotInfo type and replaces VolumeSnapshotHandlePairList with VolumeSnapshotInfoList to fix restoreSize handling when CSI drivers do not implement ListSnapshots; objects are migrated from v1beta1 via a conversion webhook and the feature remains CSI-only with GA planned later.
