Kubernetes v1.34: Autoconfiguration for Node Cgroup Driver Goes GA
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…
Kubernetes v1.34: Mutable CSI Node Allocatable Graduates to Beta
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…
Kubernetes v1.34: Use An Init Container To Define App Environment Variables
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…
Kubernetes v1.34: Snapshottable API server cache
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…
Kubernetes v1.34: VolumeAttributesClass for Volume Modification GA
The VolumeAttributesClass API, which empowers users to dynamically modify volume attributes, has officially graduated to General Availability (GA) in Kubernetes v1.34. This marks a significant milestone, providing a robust and stable way…
Kubernetes v1.34: Pod Replacement Policy for Jobs Goes GA
In Kubernetes v1.34, the Pod replacement policy feature has reached general availability (GA). This blog post describes the Pod replacement policy feature and how to use it in your Jobs. About Pod Replacement Policy By default, the Job…
Kubernetes v1.34: PSI Metrics for Kubernetes Graduates to Beta
As Kubernetes clusters grow in size and complexity, understanding the health and performance of individual nodes becomes increasingly critical. We are excited to announce that as of Kubernetes v1.34, Pressure Stall Information (PSI)…
Kubernetes v1.34: Service Account Token Integration for Image Pulls Graduates to Beta
The Kubernetes community continues to advance security best practices by reducing reliance on long-lived credentials. Following the successful alpha release in Kubernetes v1.33, Service Account Token Integration for Kubelet Credential…
Kubernetes v1.34: Introducing CPU Manager Static Policy Option for Uncore Cache Alignment
A new CPU Manager Static Policy Option called prefer-align-cpus-by-uncorecache was introduced in Kubernetes v1.32 as an alpha feature, and has graduated to beta in Kubernetes v1.34. This CPU Manager Policy Option is designed to optimize…
Kubernetes v1.34: DRA has graduated to GA
Kubernetes 1.34 is here, and it has brought a huge wave of enhancements for Dynamic Resource Allocation (DRA)! This release marks a major milestone with many APIs in the resource.k8s.io group graduating to General Availability (GA),…
Kubernetes v1.34: Finer-Grained Control Over Container Restarts
With the release of Kubernetes 1.34, a new alpha feature is introduced that gives you more granular control over container restarts within a Pod. This feature, named Container Restart Policy and Rules, allows you to specify a restart…
Kubernetes v1.34: User preferences (kuberc) are available for testing in kubectl 1.34
Have you ever wished you could enable interactive delete, by default, in kubectl? Or maybe, you'd like to have custom aliases defined, but not necessarily generate hundreds of them manually? Look no further. SIG-CLI has been working hard…
