Step by Step Kubernetes Observability with eBPF
Talkat Cloud Native eBPF Day Europe 2022 · on Monday, 2022-05-16· at 14:05· Pavilion 4 | Room A | Level 2 | Central Forum·
summary
Shows a concrete pipeline that writes a kernel eBPF probe (tcp connect), compiles it with libbpf or packages only the kernel object into an OCI image via the Bumblebee CLI, pushes with b build / b push and runs with b run, deploys it as a DaemonSet across three nodes (master, worker1, worker2), exposes counters as Prometheus metrics, correlates pod IPs to service/pod names via the Kubernetes API to build a live service graph, and the demo works end to end.
