Hubble Beyond Cilium
Talkat Cilium + eBPF Day North America 2024 · on Tuesday, 2024-11-12· at 15:20· Salt Palace | Level 1 | Grand Ballroom B·
summary
Shows how Hubble runs without Cilium by keeping Hubble server code untouched and feeding it flow objects from a new Retina agent with plugin API that attaches eBPF programs, enriches flows via a cached Cilium identity cache, and exports Prometheus metrics and Hubble UI/CLI outputs. Demonstrates feature parity for L4, drop and DNS metrics, a live comparison where policy-denied → iptables rule drop is identified, performance hits ~2.5–3 ms intra-node and ~10 ms inter-node, and scale tests with 20K pods, memory flat.
