      Emissary-Ingress is configured through Kubernetes custom resources including Mapping for routing rules, Host for
      domain configuration, TLSContext for TLS termination, RateLimitService for rate limiting, and AuthService for
      external authentication. These CRDs provide declarative API gateway configuration within the Kubernetes ecosystem.

      Emissary-Ingress supports a subset of the Kubernetes Gateway API standard, including GatewayClass, Gateway, and
      HTTPRoute resources. This enables teams to use the next-generation Kubernetes ingress standard for defining
      routing rules, with support for path matching, header matching, and weighted load balancing across backend
      services.
