Traefik
Cloud-native reverse proxy och ingress controller — Emile Vauge 2015 (Containous, numera Traefik Labs). Automatisk konfiguration via provider-discovery (Docker labels, K8s, Consul, etcd).
Skriven i Go. Built-in Let's Encrypt-integration (ACME), HTTP/2 + HTTP/3, gRPC, TCP/UDP-load-balancing. Traefik Hub är managed control plane. Traefik Mesh (lite, sidecar-less service mesh).
Default ingress controller i k3s, populärt i Docker-Compose-stacks. Konkurrent: Nginx Ingress, HAProxy, Envoy + Gateway API, Kong. Traefik vinner vid små-medel-team som vill ha "det bara funkar".
