What it is
Traefik is a reverse proxy that discovers routes from Docker labels, Kubernetes Ingress/CRDs, or config files. Built-in Let’s Encrypt and dashboard.
Usage
TLS termination; dynamic routing for containers and K8s; load balancing; middlewares (auth, headers, retry).
Pros and cons
| Pros | Cons |
|---|---|
| Dynamic config from labels/CRDs | Less battle-tested than Nginx at huge scale |
| Automatic HTTPS | |
| Good K8s/Docker integration | |
| Single binary, easy to run |
Alternatives
Nginx, Caddy. Why Traefik: Best when you want label/CRD-driven config and automatic TLS in container/K8s environments.
