In the previous post , we introduced KubeVirtBMC and showed how it provides virtual BMC endpoints for KubeVirt VMs. We tested it with raw IPMI and Redfish commands. That was fun, but the real power of...

In case you missed it: OpenTelemetry (OTel) has officially achieved CNCF graduated status! It now stands proudly alongside amazing open source projects such as Kubernetes and Prometheus, to name just a few. It’s been a long...

Dragonfly speeds up file and container image distribution using peer-to-peer (P2P) technology, but a standard installation deploys several components and dependencies. Beyond the Scheduler, Seed Client, and Client that move data, a traditional setup requires a...

Projects that want to share a GPU on Kubernetes have to work around an API instead of with it. The device plugin interface could count devices, and that was the whole vocabulary: nvidia.com/gpu: 1. It meant one...

Your GPU bill is rising. Your models are serving billions of tokens. Yet one question remains unanswered: what does each token actually cost? This is not a hypothetical problem. Platform teams today operate in a fog...

Every multi-region setup eventually meets the same awkward moment: a whole cluster goes away, and the identical copy of your service running two regions over might as well not exist, because nothing is wired to treat...

Kyverno is a Kubernetes-native policy engine that validates, mutates, and generates resources before workloads reach your cluster, enforcing security and compliance rules as code, without requiring a separate policy language. Enterprise teams running Kyverno policies in...

Dragonfly v2.5.0 is released! Thanks to all of the contributors who made this Dragonfly release happen.  New features and enhancements Direct repository downloads from Hugging Face and ModelScope Dragonfly Client now supports directly downloading model repositories...

As someone who’s been maintaining Jaeger, I’ve watched users request ClickHouse support consistently over the past few years. With Jaeger v2.18.0, we’ve finally delivered it. What excites me most isn’t just that ClickHouse is available—it’s that its architecture is...

I still remember the first time we lost sleep over something that wasn’t a bug. It was a Tuesday. Grafana dashboards showed blank panels for Cilium network metrics. Hubble was working fine — DNS visibility, TCP...

As software architectures evolve, observability tools must adapt. When the industry moved to microservices, distributed tracing became a necessity. Jaeger emerged as a core tool for engineers to understand those fragmented systems. Now, as organizations integrate...

Confidential Containers (CoCo) adds a critical security layer for containerized workloads, especially in environments where parts of the platform are not inherently trusted. However, deploying CoCo-enabled workloads often requires application teams to manage infrastructure-heavy details that...

Following our expansion into AI workflows in v2.0, Lima v2.1 introduces highly anticipated experimental support for macOS and FreeBSD guests and further hardens local environments against unpredictable AI agents. What is Lima ? Lima (Linux Machines)...

Overview Kubernetes has fundamentally transformed how enterprises deploy and manage business workloads. As organizations build production applications at scale on Kubernetes, cluster size and complexity continue to grow—creating unprecedented challenges in ensuring cluster security, compliance, and...

A production internals guide verified against Kubernetes 1.35 GACompanion repository: github.com/opscart/k8s-pod-restart-mechanics The terminology problem Engineers say “the pod restarted” when they mean four different things. Getting this wrong leads to flawed runbooks and bad on-call decisions....

As a high velocity project and one of the fastest-growing projects in the CNCF ecosystem, Meshery’s increasing scale and community contributions necessitates this recognition, which requires a revision to its governance and organizational structure that better...

Imagine you are running a bunch of microservices, each living within its own boundary. What are some of the challenges that come into mind when operating them? This is where Distributed Application Runtime (Dapr) comes into...

The Volcano community is proud to announce the launch of Kthena, a new sub-project designed for global developers and MLOps engineers. Kthena is a cloud native, high-performance system for Large Language Model (LLM) inference routing, orchestration,...

As we enter the new year, we’re excited to share the Q4 updates from the LitmusChaos community. Over the past few months, the chaos engineering ecosystem and the LitmusChaos community have continued to grow steadily, driven...

The Open Source Technology Improvement Fund is proud to share the results of our security audit of CRI-O. CRI-O is an implementation of the Kubernetes Container Runtime Interface (CRI) that is OCI-compliant (-O) that provides the...
