Intro
Traefik Fundamentals
Traefik is a proxy for application traffic. It listens at the edge of a system, decides which configured route matches a request, applies any requested middleware, and forwards the request to a backend service.

Traefik can also learn that information from a provider such as Docker, Kubernetes, a key-value store, or a file. When the provider reports a change, Traefik updates its dynamic routes.
