From PIDs to Pods - The Life Cycle of an eBPF-Autoinstrumented Kubernetes App

Explore the technical journey of integrating eBPF-based observability with Kubernetes abstractions in this 22-minute conference talk from DevConf.CZ 2025. Learn how to bridge the gap between low-level eBPF kernel inspection capabilities and high-level Kubernetes concepts like Pods, Deployments, and Services. Discover the architectural decisions and implementation strategies used in Grafana Beyla, an eBPF-based instrumentation tool, to create a unified observability experience that spans application, platform, and infrastructure layers. Understand the challenges of matching process-level data from eBPF with Kubernetes entities, and examine practical solutions for making eBPF tooling Kubernetes-native while maintaining its ability to run as a simple OS-level process. Gain insights into designing observability tools that allow Kubernetes users to maintain their familiar abstractions without needing to understand underlying operating system constructs.
