Web / Traefik Interview questions

What is the difference between Traefik's Ingress support and the IngressRoute CRD?

Traefik can act as an Ingress controller for standard Kubernetes Ingress resources, interpreting the common rules and tls fields, plus Traefik-specific behavior added through annotations.

IngressIngressRoute (CRD)
Portable across any Ingress controllerTraefik-specific, not portable to other controllers
Advanced features via annotations (limited, string-based)Advanced features as native, typed spec fields
Middleware reuse is awkwardMiddlewares are first-class, referenced by name

Teams that need to stay portable across ingress controllers tend to stick with Ingress plus annotations, while teams fully committed to Traefik often prefer IngressRoute for its cleaner expression of routers, weighted services, and middleware chains.

Both can run side by side on the same cluster, since Traefik's Kubernetes providers for Ingress and for the CRD operate independently and simply contribute their own resources into the same merged dynamic configuration.

A key advantage of Ingress over IngressRoute is:
IngressRoute expresses middleware usage as:
