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: th…

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 …

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 …

Dynamic Resource Allocation (DRA) has fundamentally changed how platform administrators handle hardware accelerators and specialized resources in Kubernetes. In the v1.36 release, DRA continues to mature, bringing a wave of feature graduations, critical usability improvements, and new capabilities that extend the flexibility of DRA to native resources like memory and CPU, and support for ResourceClaims in PodGroups. Driver availability continues to expand. Beyond specialized compute accelerator…

As Kubernetes clusters grow to tens of thousands of nodes, controllers that watch high-cardinality resources like Pods face a scaling wall. Every replica of a horizontally scaled controller receives the full stream of events from the API server, paying the CPU, memory, and network cost to deserialize everything, only to discard the objects it is not responsible for. Scaling out the controller does not reduce per-replica cost; it multiplies it. Kubernetes v1.36 introduces server-side sharded lis…

In Kubernetes v1.36, Declarative Validation for Kubernetes native types has reached General Availability (GA). For users, this means more reliable, predictable, and better-documented APIs. By moving to a declarative model, the project also unlocks the future ability to publish validation rules via OpenAPI and integrate with ecosystem tools like Kubebuilder. For contributors and ecosystem developers, this replaces thousands of lines of handwritten validation code with a unified, maintainable fra…

If you've ever tried to enforce a security policy across a fleet of Kubernetes clusters, you've probably run into a frustrating chicken-and-egg problem. Your admission policies are API objects, which means they don't exist until someone creates them, and they can be deleted by anyone with the right permissions. There's always a window during cluster bootstrap where your policies aren't active yet, and there's no way to prevent a privileged user from removing them. Kubernetes v1.36 introduces an…

Kubernetes v1.36 introduces Pod-Level Resource Managers as an alpha feature, bringing a more flexible and powerful resource management model to performance-sensitive workloads. This enhancement extends the kubelet's Topology, CPU, and Memory Managers to support pod-level resource specifications (.spec.resources), evolving them from a strictly per-container allocation model to a pod-centric one. Why do we need pod-level resource managers?When running performance-critical workloads such as machin…

Following the graduation of Pod-Level Resources to Beta in v1.34 and the General Availability (GA) of In-Place Pod Vertical Scaling in v1.35, the Kubernetes community is thrilled to announce that In-Place Pod-Level Resources Vertical Scaling has graduated to Beta in v1.36! This feature is now enabled by default via the InPlacePodLevelResourcesVerticalScaling feature gate. It allows users to update the aggregate Pod resource budget (.spec.resources) for a running Pod, often without requiring a c…

On behalf of SIG Node, we are pleased to announce updates to the Memory QoS feature (alpha) in Kubernetes v1.36. Memory QoS uses the cgroup v2 memory controller to give the kernel better guidance on how to treat container memory. It was first introduced in v1.22 and updated in v1.27. In Kubernetes v1.36, we're introducing: opt-in memory reservation, tiered protection by QoS class, observability metrics, and kernel-version warning for memory.high. What's new in v1.36Opt-in memory reservation wit…
