Distributed tracing for CI pipelines without touching a single workflow file
You’ve probably felt this one: GitHub Actions usage creeps up across your org, and your actual visibility into it doesn’t keep pace. Which workflows are slow? Which are flaky? How long are jobs sitting queued for…
Handling vulnerability reports: Recipe card
Recipe Handling Vulnerability Reports Target audience (the chef) This recipe is aimed at small and medium non-security focused projects. Maintainers of a high-risk security sensitive project, you probably need a more sophisticated approach (check out https://alpha-omega.dev/) Scope…
Metal3 meets KubeVirtBMC: Provisioning KubeVirt VMs like bare metal
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…
Observability in Kubernetes: From metrics to meaning
Kubernetes 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…
Scale before the spike: Predictive autoscaling for GPU workloads on Kubernetes
The 3 AM Call We got paged one Tuesday morning. A critical production service had crashed under traffic—not gradually degraded, but crashed. Hundreds of pending pods. Users were seeing 15–20% error rates. The incident postmortem was…
Building an AI factory on Kubernetes
An AI factory is not just a model or a cluster. It is a pool of GPUs that many teams draw from at once: one team fine-tuning, another serving inference, a third running evaluations, all on…
The lazy developer’s guide to observing your own code
It’s no secret that developers are increasingly being asked to shift left. It seems there’s always something new to shift left on. And now developers are being asked to shift left on observability. This means that…
How to turn slow queries into actionable reliability metrics with OpenTelemetry
Slow SQL queries degrade user experience, cause cascading failures, and turn simple operations into production incidents. The traditional fix? Collect more telemetry. But more telemetry means more things to look at, not necessarily more understanding. Instead…
A practical guide to solving when zero+zero=two in mesh observability
A Service Mesh like Istio, together with Kiali gives you a lot on day one. You install the mesh, point Prometheus at it, and suddenly you have request rate, latency, error rate, and a fairly good…
Does Kubernetes DRA Replace HAMi?
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…
