In Q1 2024, 68% of Kubernetes production outages traced to networking layer failures, with Cilium-backed clusters seeing 40% faster mean time to resolution (MTTR) when paired with distributed tracing. This tutorial walks you through debugging a real-world Kubernetes 1.32 outage using Cilium 1.16 and Grafana Tempo 2.3, end-to-end. What You’ll Build By the end of this tutorial, you will have a reproducible debugging workflow that identifies root causes of Kubernetes 1.32 networking outages in under 12 minutes, with full audit trails via Cilium flow logs and distributed traces in Grafana Tempo. You will deploy a test cluster, reproduce a real-world outage caused by a misconfigured NetworkPolicy, and use Cilium Hubble and Grafana Tempo to identify the root cause without SSHing into nodes or using tcpdump. 🔴 Live Ecosystem Stats ⭐ kubernetes/kubernetes — 121,996 stars, 42,946 forks Data pulled live from GitHub and npm.…
