• Kubernetes Configuration Good Practices 2025-11-25
  Configuration is one of those things in Kubernetes that seems small until it's not. Configuration is at the heart of every Kubernetes workload. A missing quote, a wrong API version or a misplaced YAML indent can ruin your entire deploy. This blog brings together tried-and-tested configuration best practices. The small habits that make your Kubernetes […]
• Ingress NGINX Retirement: What You Need to Know 2025-11-11
  To prioritize the safety and security of the ecosystem, Kubernetes SIG Network and the Security Response Committee are announcing the upcoming retirement of Ingress NGINX. Best-effort maintenance will continue until March 2026. Afterward, there will be no further releases, no bugfixes, and no updates to resolve any security vulnerabilities that may be discovered. Existing deployments […]

  Ready to rock your Kubernetes networking? The Kubernetes SIG Network community presented the General Availability (GA) release of Gateway API (v1.4.0)! Released on October 6, 2025, version 1.4.0 reinforces the path for modern, expressive, and extensible service networking in Kubernetes. Gateway API v1.4.0 brings three new features to the Standard channel (Gateway API's GA release […]
• 7 Common Kubernetes Pitfalls (and How I Learned to Avoid Them) 2025-10-20
  It’s no secret that Kubernetes can be both powerful and frustrating at times. When I first started dabbling with container orchestration, I made more than my fair share of mistakes enough to compile a whole list of pitfalls. In this post, I want to walk through seven big gotchas I’ve encountered (or seen others run […]
• Spotlight on Policy Working Group 2025-10-18
  (Note: The Policy Working Group has completed its mission and is no longer active. This article reflects its work, accomplishments, and insights into how a working group operates.) In the complex world of Kubernetes, policies play a crucial role in managing and securing clusters. But have you ever wondered how these policies are developed, implemented, […]
• Introducing Headlamp Plugin for Karpenter - Scaling and Visibility 2025-10-06
  Headlamp is an open‑source, extensible Kubernetes SIG UI project designed to let you explore, manage, and debug cluster resources. Karpenter is a Kubernetes Autoscaling SIG node provisioning project that helps clusters scale quickly and efficiently. It launches new nodes in seconds, selects appropriate instance types for workloads, and manages the full node lifecycle, including scale-down. […]
• Announcing Changed Block Tracking API support (alpha) 2025-09-25
  We're excited to announce the alpha support for a changed block tracking mechanism. This enhances the Kubernetes storage ecosystem by providing an efficient way for CSI storage drivers to identify changed blocks in PersistentVolume snapshots. With a driver that can use the feature, you could benefit from faster and more resource-efficient backup operations. If you're […]
• Kubernetes v1.34: Pod Level Resources Graduated to Beta 2025-09-22
  On behalf of the Kubernetes community, I am thrilled to announce that the Pod Level Resources feature has graduated to Beta in the Kubernetes v1.34 release and is enabled by default! This significant milestone introduces a new layer of flexibility for defining and managing resource allocation for your Pods. This flexibility stems from the ability […]
• Kubernetes v1.34: Recovery From Volume Expansion Failure (GA) 2025-09-19
  Have you ever made a typo when expanding your persistent volumes in Kubernetes? Meant to specify 2TB but specified 20TiB? This seemingly innocuous problem was kinda hard to fix - and took the project almost 5 years to fix. Automated recovery from storage expansion has been around for a while in beta; however, with the […]
• Kubernetes v1.34: DRA Consumable Capacity 2025-09-18
  Dynamic Resource Allocation (DRA) is a Kubernetes API for managing scarce resources across Pods and containers. It enables flexible resource requests, going beyond simply allocating N number of devices to support more granular usage scenarios. With DRA, users can request specific types of devices based on their attributes, define custom configurations tailored to their workloads, […]
• Kubernetes v1.34: Pods Report DRA Resource Health 2025-09-17
  The rise of AI/ML and other high-performance workloads has made specialized hardware like GPUs, TPUs, and FPGAs a critical component of many Kubernetes clusters. However, as discussed in a previous blog post about navigating failures in Pods with devices, when this hardware fails, it can be difficult to diagnose, leading to significant downtime. With the […]
• Kubernetes v1.34: Moving Volume Group Snapshots to v1beta2 2025-09-16
  Volume group snapshots were introduced as an Alpha feature with the Kubernetes 1.27 release and moved to Beta in the Kubernetes 1.32 release. The recent release of Kubernetes v1.34 moved that support to a second beta. The support for volume group snapshots relies on a set of extension APIs for group snapshots. These APIs allow […]
• Kubernetes v1.34: Decoupled Taint Manager Is Now Stable 2025-09-15
  This enhancement separates the responsibility of managing node lifecycle and pod eviction into two distinct components. Previously, the node lifecycle controller handled both marking nodes as unhealthy with NoExecute taints and evicting pods from them. Now, a dedicated taint eviction controller manages the eviction process, while the node lifecycle controller focuses solely on applying taints. […]
• Kubernetes v1.34: Autoconfiguration for Node Cgroup Driver Goes GA 2025-09-12
  Historically, configuring the correct cgroup driver has been a pain point for users running new Kubernetes clusters. On Linux systems, there are two different cgroup drivers: cgroupfs and systemd. In the past, both the kubelet and CRI implementation (like CRI-O or containerd) needed to be configured to use the same cgroup driver, or else the […]
• Kubernetes v1.34: Mutable CSI Node Allocatable Graduates to Beta 2025-09-11
  The functionality for CSI drivers to update information about attachable volume count on the nodes, first introduced as Alpha in Kubernetes v1.33, has graduated to Beta in the Kubernetes v1.34 release! This marks a significant milestone in enhancing the accuracy of stateful pod scheduling by reducing failures due to outdated attachable volume capacity information. Background […]
• Kubernetes v1.34: Use An Init Container To Define App Environment Variables 2025-09-10
  Kubernetes typically uses ConfigMaps and Secrets to set environment variables, which introduces additional API calls and complexity, For example, you need to separately manage the Pods of your workloads and their configurations, while ensuring orderly updates for both the configurations and the workload Pods. Alternatively, you might be using a vendor-supplied container that requires environment […]
• Kubernetes v1.34: Snapshottable API server cache 2025-09-09
  For years, the Kubernetes community has been on a mission to improve the stability and performance predictability of the API server. A major focus of this effort has been taming list requests, which have historically been a primary source of high memory usage and heavy load on the etcd datastore. With each release, we've chipped […]
