Zero-Cost Linkerd at Adidas: Impossible Is Nothing
Talkat Linkerd Day Europe 2023 · on Tuesday, 2023-04-18· at 09:15· Hall 7, Room D | Ground Floor | Europe Complex·
summary
Five engineers integrate Linkerd into Adidas with a small operational footprint, connecting to VictoriaMetrics, Grafana, Venafi (CA per cluster), Kafka buffering (prompt-to-kafka / kafka-to-prom), OpenTelemetry → Tempo, and an external-secrets → cert-manager flow for cluster ECDSA certs. Target was one production service per quarter but timeline slips; proxies add ~2–3 ms latency; retries in the mesh cut critical checkout failures; multi-tenant dev cluster serves >1,000 users; contributed CLI fixes for ECDSA+RSA validation and reduced CLI permissions.
