Kubernetes Observability with eBPF
summary
Covers the actual eBPF execution path: C source compiles to bytecode, goes through the kernel verifier, JITs to native instructions and runs on hooks; demonstrates toolchains BCC and libbpf and introduces BumbleBee’s workflow to B build an OCI image and B run it on a node where a shim loads bytecode and exposes BPF maps as Prometheus metrics; contrasts eBPF/Cilium routing vs iptables; demo compilation hits an error but BumbleBee’s build → push → load pattern and Prometheus integration are shown end to end.
