I Ran Traefik in Production for a Year Before I Really Understood It
The questions I should have asked before copying my first Middleware: how Traefik differs from NGINX beyond the YAML, which traffic it actually sees, what happens to a request between the entrypoint and the pod, why some changes need a restart, what a TLS 1.3 handshake really does with the certificate, and why we run more than one instance per cluster.
