Kubernetes v1.37 promotes the metrics.k8s.io API to stable (v1). This API provides CPU and memory usage for nodes and Pods, and is the API behind commands such as kubectl top and resource-metrics-based autoscaling. For cluster operators and application developers, this graduation means that the API now has the stability guarantees associated with a Kubernetes stable API. The v1 API has the same resource types and fields as v1beta1; this is an API-version graduation, not a change to the metrics that are collected or returned. A long-lived API reaches stableThe resource Metrics API was introduced as alpha in Kubernetes v1.6 and became beta in …

The Kubernetes SIG Network community is thrilled to share the release of Gateway API v1.6.0, which was released on June 30th of this year! Gateway API has become the standard for modern, role-oriented, and expressive service networking in Kubernetes. In previous releases, Gateway API established a production-grade foundation for HTTP and TLS layer 7 traffic. With version 1.6.0, Gateway API takes a major step forward by expanding standard layer 4 protocol routing and introducing cleaner API boundaries for experimental innovation. Here is a quick summary of what's new in Gateway API v1.6.0: TCPRoute and UDPRoute Graduate to Standard: Raw L4 TC…

As we get closer to the release date for Kubernetes v1.37, the project develops and matures, features may be deprecated, removed, or replaced with better ones for the project's overall health. This blog outlines some of the planned changes for the Kubernetes v1.37 release that the release team feels you should be aware of for the continued maintenance of your Kubernetes environment and keeping up to date with the latest changes. The information below reflects the current status of the v1.37 release and may change before the actual release date.

Kubernetes ships with built-in awareness of CPU and memory, but most real-world scaling decisions depend on signals that live entirely outside that narrow window: how many messages are waiting in a queue, how long the last batch job took, how many active WebSocket connections a pod is holding. When the built-in metrics are not enough, a metrics exporter bridges that gap. This post walks through writing one from scratch, packaging it as a container, and wiring it into a cluster so that Prometheus — and ultimately the HorizontalPodAutoscaler — can consume it. What a metrics exporter actually doesAn exporter is a small HTTP server with a single…

In our ongoing SIG Spotlight series, we shine a light on the groups that keep the Kubernetes project moving forward. This time, we catch up with SIG Storage, the group responsible for persistent data, volume management, and the interfaces that connect Kubernetes workloads to the storage systems beneath them. We spoke with Xing Yang, Co-Chair of SIG Storage and Software Engineer at VMware by Broadcom, about the SIG's history, the features shipping in recent Kubernetes releases, and where storage in Kubernetes is headed as AI workloads become the norm. IntroductionsCould you introduce yourself and share your role(s) within SIG Storage? My name…

This article was originally published with the wrong date. It was later republished, dated the 15th of May 2026. Kubernetes v1.36 introduces a new alpha counter metric route_controller_route_sync_total to the Cloud Controller Manager (CCM) route controller implementation at k8s.io/cloud-provider. This metric increments each time routes are synced with the cloud provider. A/B testing watch-based route reconciliationThis metric was added to help operators validate the CloudControllerManagerWatchBasedRoutesReconciliation feature gate introduced in Kubernetes v1.35. That feature gate switches the route controller from a fixed-interval loop to a …

AI/ML and batch workloads introduce unique scheduling challenges that go beyond simple Pod-by-Pod scheduling. In Kubernetes v1.35, we introduced the first tranche of workload-aware scheduling improvements, featuring the foundational Workload API alongside basic gang scheduling support built on a Pod-based framework, and an opportunistic batching feature to efficiently process identical Pods. Kubernetes v1.36 introduces a significant architectural evolution by cleanly separating API concerns: the Workload API acts as a static template, while the new PodGroup API handles the runtime state. To support this, the kube-scheduler features a new Pod…

Since its original implementation in the Linux kernel in 2018, Pressure Stall Information (PSI) has provided users with the high-fidelity signals needed to identify resource saturation before it becomes an outage. Unlike traditional utilization metrics, PSI tells the story of tasks stalled and time lost, all in nicely-packaged percentages of time across the CPU, memory, and I/O. With the recent release of Kubernetes v1.36, users across the ecosystem have a stable, reliable interface to observe resource contention at the node, pod, and container levels. In this post, we will dive into the improvements and performance testing that proved its r…

Volume group snapshots were introduced as an Alpha feature with the Kubernetes v1.27 release, moved to Beta in v1.32, and to a second Beta in v1.34. We are excited to announce that in the Kubernetes v1.36 release, support for volume group snapshots has reached General Availability (GA). The support for volume group snapshots relies on a set of extension APIs for group snapshots. These APIs allow users to take crash-consistent snapshots for a set of volumes. Behind the scenes, Kubernetes uses a label selector to group multiple PersistentVolumeClaim objects for snapshotting. A key aim is to allow you to restore that set of snapshots to new vol…
