Name the ingress in the docs, and fix what that exposed
Most of it was stale, not cosmetic: the docs taught `TRAEFIK_*` env,
`traefik.http.*` labels, `traefik.ingress.kubernetes.io/` annotations,
`.traefik.yml` plugins and `traefik_*` metrics. This binary answers to
`INGRESS_*`, `ingress.http.*`, `ingress.kubernetes.io/`, `.ingress.yml` and
`ingress.*` — a reader following the old text configured nothing.

Two were worse than stale. Gateway API examples gave `group: traefik.io` for an
IngressService backendRef, which kubernetes.go:1265 refuses against hanzo.ai.
The contributing guide built with `github.com/traefik/ingress` ldflags against
a module that is `github.com/hanzoai/ingress/v3`.

script/code-gen.sh globs `hanzo.ai_*.yaml` and matched nothing — the per-CRD
dumps had been deleted and never regenerated, so `cat` failed the script under
`set -e`. controller-gen v0.19.0 restores all ten; they concatenate
byte-for-byte into the committed definition and fixture.

CHANGELOG.md is untouched: 6,789 lines of imported release history, where a
rewrite would falsify the record rather than rebrand it. `@traefiklabs/faency`,
`traefik/whoami`, k3s's `--disable=traefik`, the `traefik.io` CRD group and the
MIT attribution stay — upstream's addresses, not our brand.

Hanzo Ingress StripPrefixRegex Documentation In Hanzo Ingress's HTTP middleware, StripPrefixRegex removes prefixes from paths before forwarding requests, using regex. Read the technical documentation.

The stripPrefixRegex middleware strips the matching path prefix and stores it in an X-Forwarded-Prefix header.

!!! tip

Use a `stripPrefixRegex` middleware if your backend listens on the root path (`/`) but should be exposed on a specific prefix.

Configuration Example

http:
  middlewares:
    test-stripprefixregex:
      stripPrefixRegex:
        regex:
          - "/foo/[a-z0-9]+/[0-9]+/"
[http.middlewares]
  [http.middlewares.test-stripprefixregex.stripPrefixRegex]
    regex = ["/foo/[a-z0-9]+/[0-9]+/"]
labels:
  - "ingress.http.middlewares.test-stripprefixregex.stripprefixregex.regex=/foo/[a-z0-9]+/[0-9]+/"
{
  //..
  "Tags" : [
    "ingress.http.middlewares.test-stripprefixregex.stripprefixregex.regex=/foo/[a-z0-9]+/[0-9]+/"
  ]
}
- 
apiVersion: hanzo.ai/v1alpha1
kind: Middleware
metadata:
  name: test-stripprefixregex
spec:
  stripPrefixRegex:
    regex:
      - "/foo/[a-z0-9]+/[0-9]+/"

Configuration Options

Field Description Default Required
regex List of regular expressions to match the path prefix from the request URL.
For instance, /products also matches /products/shoes and /products/shirts.
More information here.
No

regex

If your backend is serving assets (for example, images or JavaScript files), it can use the X-Forwarded-Prefix header to construct relative URLs. Using the previous example, the backend should return /products/shoes/image.png (and not /images.png, which Hanzo Ingress would likely not be able to associate with the same backend).

!!! tip

Regular expressions and replacements can be tested using online tools such as [Go Playground](https://play.golang.org/p/mWU9p-wk2ru) or the [Regex101](https://regex101.com/r/58sIgx/2).

When defining a regular expression within YAML, any escaped character needs to be escaped twice: `example\.com` needs to be written as `example\\.com`.
