Kubernetes v1.37 promotes the KubeletInUserNamespace feature gate to beta. With this feature enabled, all of the node components (kubelet, CRI and OCI runtimes, CNI plugins, and kube-proxy) can run as a non-root user on the host, using a Linux user namespace . This technique is also known as rootless mode . The work s…
Read at sourceAI infrastructure conversations often start with GPUs. Accelerators provide much of the compute behind model training and inference, so the focus is understandable. But a production AI workload rarely starts and ends on a GPU. Data...
Read at sourceKubernetes isn’t brand new anymore. Yet, for many teams, adopting it still feels intimidating. Even if you’ve watched Kubernetes become the default foundation for production software and AI workloads, it can still feel like a big...
Read at sourceKubernetes 1.37 is here and Dynamic Resource Allocation (DRA) keeps pushing past where it started! This release brings DRA Extended Resource support to GA, a milestone the team has been building toward for three straight releases. Several more features graduate to Beta or GA. A fresh batch of alpha features rounds out…

Read at sourceKubernetes v1.37 includes API support for horizontal autoscaling of workloads down to zero replicas. This feature is now Beta and enabled by default. A HorizontalPodAutoscaler (HPA) that uses a suitable object metric or external metric can now scale a workload to zero replicas, then bring it back when the metric chang…

Read at sourceI am excited to announce that etcd RangeStream is graduating to beta in Kubernetes v1.37. Paired with etcd v3.7, it reduces the memory the API server and etcd need to read a large collection, and makes peak usage more predictable. The cost of large reads The API server serves most list and watch requests from its in-m…

Read at sourceI am excited that storage version migration (SVM) has graduated to General Availability (GA) in Kubernetes v1.37! After a number of releases of work and testing, the built-in StorageVersionMigration API ( storagemigration.k8s.io/v1 ) and control plane controller are now fully stable and enabled by default across all v…

Read at sourceKubernetes made infrastructure more programmable, scalable, and resilient. It also made production systems harder to reason about. Workloads move, replicas churn, dependencies multiply, and a single user request can cross ingress, services, queues, storage, and background...

Read at sourceKubernetes has given platform teams a consistent way to deploy, scale, and operate containerized applications. Now, many of those same teams are being asked to support AI. The transition is already underway. According to the CNCF...
Read at sourceKubernetes v1.37 promotes the metrics.k8s.io API to stable ( v1 ). This API provides CPU and memory usage for nodes and Pods, and is the API behind commands such as kubectl top and resource-metrics-based autoscaling. For cluster operators and application developers, this graduation means that the API now has the stabi…
