DEVIATIONS

Hanzo Ingress is a source fork of Traefik. The changes relative to upstream are:

- Rebranded to "Hanzo Ingress"; the Go module path is
  github.com/hanzoai/ingress.
- The standalone binary is built from cmd/ingress (upstream cmd/traefik) and
  ships as hanzo-ingress.
- The configuration parser is forked to github.com/hanzoai/ingress-parser
  (root name "ingress", INGRESS_ environment prefix).
- Auxiliary runtime libraries resolve to Hanzo source forks via go.mod replace,
  keeping the upstream import paths: github.com/traefik/yaegi =>
  github.com/hanzoai/yaegi, github.com/traefik/grpc-web =>
  github.com/hanzoai/grpc-web, github.com/vulcand/oxy/v2 =>
  github.com/hanzoai/oxy/v2.
- The Kubernetes CRD API group is hanzo.ai.
- The Kubernetes Ingress annotation prefix is ingress.kubernetes.io/.
- The Prometheus metric prefix is ingress_.
- Internal proxy headers are renamed: X-Traefik-Fast-Proxy => X-Ingress-Fast-Proxy,
  X-Traefik-Router => X-Ingress-Router.
- A HIP-0106 in-process mount surface (mount.go) exposes the ingress for the
  Hanzo unified-binary stack.
- A ZAP-HTTP backend transport (pkg/server/service/zap_backend.go) dials backends
  listed in INGRESS_ZAP_BACKENDS over github.com/zap-proto/http.
- The upstream release check is disabled (version.CheckNewVersion is a no-op);
  the version endpoint is served at /v1/ingress/version.
