- Kubernetes v1.35: Restricting executables invoked by kubeconfigs via exec plugin allowList added to kuberc 2026-01-09Did you know that kubectl can run arbitrary executables, including shell scripts, with the full privileges of the invoking user, and without your knowledge? Whenever you download or auto-generate a kubeconfig, the users[n].exec.command field can specify an executable to fetch credentials on your behalf. Don't get me wrong, this is an incredible feature that allows […]
- Kubernetes v1.35: Mutable PersistentVolume Node Affinity (alpha) 2026-01-08The PersistentVolume node affinity API dates back to Kubernetes v1.10. It is widely used to express that volumes may not be equally accessible by all nodes in the cluster. This field was previously immutable, and it is now mutable in Kubernetes v1.35 (alpha). This change opens a door to more flexible online volume management. Why […]
- Kubernetes v1.35: A Better Way to Pass Service Account Tokens to CSI Drivers 2026-01-07If you maintain a CSI driver that uses service account tokens, Kubernetes v1.35 brings a refinement you'll want to know about. Since the introduction of the TokenRequests feature, service account tokens requested by CSI drivers have been passed to them through the volume_context field. While this has worked, it's not the ideal place for sensitive […]
- Kubernetes v1.35: Extended Toleration Operators to Support Numeric Comparisons (Alpha) 2026-01-05Many production Kubernetes clusters blend on-demand (higher-SLA) and spot/preemptible (lower-SLA) nodes to optimize costs while maintaining reliability for critical workloads. Platform teams need a safe default that keeps most workloads away from risky capacity, while allowing specific workloads to opt-in with explicit thresholds like "I can tolerate nodes with failure probability up to 5%". Today, […]
- Kubernetes v1.35: New level of efficiency with in-place Pod restart 2026-01-02The release of Kubernetes 1.35 introduces a powerful new feature that provides a much-requested capability: the ability to trigger a full, in-place restart of the Pod. This feature, Restart All Containers (alpha in 1.35), allows for an efficient way to reset a Pod's state compared to resource-intensive approach of deleting and recreating the entire Pod. […]
- Kubernetes 1.35: Enhanced Debugging with Versioned z-pages APIs 2025-12-31Debugging Kubernetes control plane components can be challenging, especially when you need to quickly understand the runtime state of a component or verify its configuration.

What are z-pages? z-pages are special […]
- Kubernetes v1.35: Watch Based Route Reconciliation in the Cloud Controller Manager 2025-12-30Up to and including Kubernetes v1.34, the route controller in Cloud Controller Manager (CCM) implementations built using the k8s.io/cloud-provider library reconciles routes at a fixed interval. This causes unnecessary API requests to the cloud provider when there are no changes to routes. Other controllers implemented through the same library already use watch-based mechanisms, leveraging informers […]
- Kubernetes v1.35: Introducing Workload Aware Scheduling 2025-12-29Scheduling large workloads is a much more complex and fragile operation than scheduling a single Pod, as it often requires considering all Pods together instead of scheduling each one independently. For example, when scheduling a machine learning batch job, you often need to place each worker strategically, such as on the same rack, to make […]
- Kubernetes v1.35: Fine-grained Supplemental Groups Control Graduates to GA 2025-12-23On behalf of Kubernetes SIG Node, we are pleased to announce the graduation of fine-grained supplemental groups control to General Availability (GA) in Kubernetes v1.35!

Issue summary Recently, the etcd community addressed an issue that may appear when […]
- Kubernetes 1.35: In-Place Pod Resize Graduates to Stable 2025-12-19This release marks a major step: more than 6 years after its initial conception, the In-Place Pod Resize feature (also known as In-Place Pod Vertical Scaling), first introduced as alpha in Kubernetes v1.27, and graduated to beta in Kubernetes v1.33, is now stable (GA) in Kubernetes 1.35! This graduation is a major milestone for improving […]
- Kubernetes v1.35: Job Managed By Goes GA 2025-12-18In Kubernetes v1.35, the ability to specify an external Job controller (through .spec.managedBy) graduates to General Availability. This feature allows external controllers to take full responsibility for Job reconciliation, unlocking powerful scheduling patterns like multi-cluster dispatching with MultiKueue. Why delegate Job reconciliation? The primary motivation for this feature is to support multi-cluster batch scheduling architectures, […]
