- Kubernetes v1.34: Recovery From Volume Expansion Failure (GA) 2025-09-19Have 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 2025-09-18Dynamic Resource Allocation (DRA) is a Kubernetes API for managing scarce resources across Pods and containers.

- Kubernetes v1.34: Decoupled Taint Manager Is Now Stable 2025-09-15This 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 2025-09-12Historically, 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 2025-09-11The 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 This marks a significant milestone in enhancing the accuracy of stateful pod scheduling by reducing failures due to outdated attachable volume capacity information.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 2025-09-10Kubernetes 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 2025-09-09For 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 […]
