Developer News

The ballots for the Steering Committee Elections are due on October 24th. If you haven’t already, submit your Steering votes. If you have contributed to Kubernetes in the last year but haven’t met the eligibility requirements, you will need to submit an exception request to vote in the steering election, the deadline for which is October 22nd.

The CFP for Maintainer Summit: KubeCon + CloudNativeCon Europe 2026 is open. Please send in your submissions before 14th December 2025.

SIG-Testing is continuing to improve alpha/beta feature coverage, including moving kind-beta-features to release blocking and several other beta jobs to release-informing.

Release Schedule

Next Deadline: Docs Deadline for placeholder PRs, October 23

We are in PRR freeze. Enhancements Freeze will begin this week (16th October). If you are going to miss the deadline, please file an Exception.

Patch releases have been delayed until 22nd October.

Featured PRs

134433 : kubeadm print errors during control-plane-wait retries

This PR improves troubleshooting during control plane startup by ensuring that errors encountered while waiting for control plane components are printed during each retry at log verbosity level 5. Previously, these errors were not shown, which made it harder to identify issues when components failed to become ready. With this change, administrators can now see the actual errors without additional steps, making failure causes more visible and debugging faster.

KEP of the Week

KEP-4622: New TopologyManager Policy which configure the value of maxAllowableNUMANodes

This KEP introduces a new TopologyManager policy option called max-allowable-numa-nodes, allowing users to configure the maximum number of NUMA nodes supported by the TopologyManager. Previously, this value was hardcoded to 8 as a temporary measure to prevent state explosion. By making it configurable, the KEP enables better support for high-end CPUs with more than 8 NUMA nodes, without changing existing TopologyManager policies or addressing broader resource management aspects.

This KEP is tracked as stable in v1.35

The Data Engineer's guide to optimizing Kubernetes, with Niels Claeys

https://ku.bz/hGRfkzDJW

Niels Claeys shares how his team at DataMinded built Conveyor, a data platform processing up to 1.5 million core hours monthly. He explains the specific optimizations they discovered through production experience, from scheduler changes that immediately reduce costs by 10-15% to achieving 97% spot instance usage without reliability issues.

You will learn:

Why the default Kubernetes scheduler wastes money on batch workloads and how switching from "least allocated" to "most allocated" scheduling enables faster scale-down and better resource utilization

How to achieve 97% spot instance adoption through strategic instance type diversification, region selection, and Spark-specific techniques

Node pool design principles that balance Kubernetes overhead with workload efficiency

Platform-specific gotchas like AWS cross-AZ data transfer costs that can spike bills unexpectedly

Why Your Infrastructure AI Sucks (And How to Fix It)

Discover why your AI agent is completely failing at infrastructure management and learn to build an AI-powered Internal Developer Platform that actually works. Most organizations are treating AI like a search engine, asking vague questions and getting generic answers that break in production. This video reveals the five critical components that transform useless AI into intelligent infrastructure automation.

You'll learn to build capabilities discovery using Vector databases for semantic search across Kubernetes resources, capture organizational patterns from tribal knowledge and documentation, create enforceable policies that guide AI toward compliance, implement proper context management to avoid the bloated mess most systems become, and design intelligent workflows that guide users to the right solutions instead of relying on guesswork. Watch as we demonstrate the complete transformation from a generic AI response to a fully functional PostgreSQL deployment that follows organizational patterns, enforces compliance policies, and deploys correctly the first time.

Featured PRs

133697: Codify feature gate dependencies

With this PR, feature gate dependencies can be explicitly declared and enforced. This has been ad-hoc or implicit in the past. Components will now refuse to start if a feature is enabled without its required dependencies. Feature Owners should review the backfilled dependencies, while users who manually toggle feature gates must ensure dependent features are also enabled—especially noting that AllAlpha=true now requires AllBeta=true or equivalent beta features to be set.

KEP of the Week

KEP 859: Include kubectl command metadata in http request headers

This KEP aims to add extra HTTP headers to kubectl requests sent to the Kubernetes apiserver. These headers would share details such as which kubectl command was used, the flags included, a session ID, and whether the command is deprecated. This would help cluster administrators understand how users interact with the cluster, making it easier to debug issues, track usage, and gather insights, without exposing any sensitive data.

This KEP is tracked for GA in v1.35

Other Merges

Disable SchedulerAsyncAPICalls feature gate to prevent scheduler performance issues under high API server load.

Add path normalization to error matcher for improved field validation.

DeviceClass now enforces a maximum of 32 selectors and configs via declarative validation.

Add declarative validation +k8s:maxItems tag to ResourceClaim

HPA controller now exposes desired_replicas metric to track scaling history.

Fix preemptor pod behavior to prevent endless scheduling loops during slow victim deletion.

Feature gate dependencies are now explicit and validated at startup, preventing enabling a feature if its dependencies are disabled.

kube-scheduler introduces lightweight AssumeCache in VolumeBinding plugin to fix occasional pod scheduling delays.

Version Updates

etcd to v3.6.5

Subprojects and Dependency Updates

cluster-api v1.11.2 extends Kubernetes support to v1.34 for both management and workload clusters, adds CoreDNS migration v1.0.28, and introduces Metal3 as an IPAM provider.

cluster-api v1.10.7 adds Kubernetes v1.33 compatibility and updates CoreDNS migration to v1.0.28.

coredns v1.13.1 updates Go to v1.25.2 to address security issues, improves performance, and enhances the sign plugin by rejecting invalid UTF-8 tokens.

Shoutouts

Drew Hagen – I’d like to take a moment to acknowledge @Matteo for the seriously impressive leadership of a newer release branch management shadow program for the 1.34 release, and all the amazing work putting together strong documentation for branch management!! I remember my experience releasing alpha 3 being very clear what to do and going really smooth. Very little tribal knowledge. And we did most releases async, which I think speaks to how strong this handbook is. I thank you for still being around to observe and help, even if it meant some later nights in your time zone. @xmudrii @jimangel Great work! Y’all have set the foundation for many more cycles to come. Thank you for all of your patience, guidance and support. It was really great learning and working with you all @Angelos Kolaitis @satyampsoni

Kubernetes Controllers Deep Dive: How They Really Work

Most people using Kubernetes know how to write YAML and run kubectl apply, but when things break, they're completely lost. The secret they're missing? Understanding controllers - the beating heart that makes Kubernetes actually work. Controllers are what automatically restart your crashed pods, scale your applications, and make custom resources feel native to the platform.

This video dives deep into the real mechanics of how Kubernetes controllers operate. You'll discover how controllers consume and emit events to coordinate with each other, how the reconciliation loop continuously maintains your desired state, and how the Watch API efficiently streams changes without overwhelming the system. We'll explore custom resource definitions that extend Kubernetes, controller communication patterns, and the event-driven architecture that makes everything self-healing. Whether you're debugging cluster issues or building your own controllers, this knowledge will transform how you think about Kubernetes from just throwing YAML at the wall to truly understanding the orchestration engine underneath.
