feat(authup): open the global schema node and let HTTPRoute rules carry matches/filters - #13
Merged

Conversation
helm copies a parent chart's ENTIRE global map into every subchart's values
and then validates them against that subchart's own schema, both inside
ToRenderValues and before a single template renders. The generated schema
closed `global` with additionalProperties: false, so any umbrella chart that
set a global this chart does not declare could not render at all:
$ helm template u parent # parent values: global.myOrgTenant
Error: values don't meet the specifications of the schema(s) in the
following chart(s):
authup:
- global: Additional property myOrgTenant is not allowed
That fires for global.imagePullPolicy, bitnami's global.storageClass and
global.compatibility.*, and for global.security.allowInsecureImages, which
DESIGN.md itself tells operators to set. No values file can work around it:
nulling the key in the subchart section leaves it as an additional property,
and nulling `global` outright trips the root-level required entry instead.
`global` is the one node in a values tree a chart does not own.
The `# @Schema additionalProperties: true` opt-out also drops `global` from
the root required list, so `authup: {global: null}` stays legal for consumers
who want to block propagation. `type: object` is kept, so a scalar `global`
still fails, and the three globals the chart consumes keep their types. Typo
detection everywhere else is unaffected.
ci/default-values.yaml carries a stray global key as the regression guard:
`make template` and the kind matrix both render it.
Closes #11
server.route / adminConsole.route rendered a single rule that was nothing but
backendRefs. Per the Gateway API, a rule with no `matches` defaults to a
PathPrefix "/" match, so that rule matches every request on every hostname the
route attaches to. The route hostname is derived from the public URL's ORIGIN
and authup.urlOrigin drops the path, which made the chart's own documented
sub-path topology emit a silent catch-all:
server.publicUrl: https://hub.example.com/auth
server.route.enabled: true
-> hostnames: [hub.example.com], rules: [{backendRefs: [...]}]
With both services on one shared host the two routes tie on every Gateway API
precedence rule and the alphabetical tie-break sends /auth to the admin
console. No value could correct it: the route objects were closed
(additionalProperties: false) with only enabled/hostnames/parentRefs/
annotations, and Gateway API has no annotation equivalent of the
proxy-buffer-size workaround the chart documents for ingress-nginx (NGINX
Gateway Fabric needs an ExtensionRef filter to a SnippetsFilter, a spec field).
`matches` and `filters` are raw Gateway API passthrough, tpl-rendered like
every other list value, so an umbrella can compose them from parent state.
Both default to [] and the rendered output without them is byte-identical to
before. This is the parity the Ingress renderer already had via extraPaths /
extraHosts / extraTls / extraRules.
validations.yaml now fails the render when a route is enabled, the public URL
carries a non-root path and `matches` is empty, quoting the match and the
URLRewrite filter to set. authup always serves at "/" and expects the proxy to
strip the prefix, so the chart cannot derive the match on its own: a
PathPrefix match without the rewrite would forward /auth/token to a server
that only serves /token. The guard reads the URL after derivation, so an
ingress-derived public URL is covered too.
Also corrects two doc strings: ingress.extraRules is appended after the
generated rules rather than overriding them, and route.hostnames notes that
only the host survives the derivation.
Closes #12

The render guard only fires when route.matches is empty, so an operator who sets matches from the start never sees the message that names the URLRewrite. authup always serves at "/" and relies on something upstream stripping the prefix, and getting that wrong 404s every request instead of failing the render. Left as a NOTE rather than a validation: the stripping may legitimately happen outside this HTTPRoute (an edge proxy or ingress in front of the gateway, or an implementation-specific filter such as an NGINX Gateway Fabric SnippetsFilter), so requiring a URLRewrite filter here would fail renders that are correct.

Drop the Hub-specific global.flameHub.authup.* knobs. authup 0.2.2 gained server.route.matches/filters, so the subchart can render its own HTTPRoute including the /auth prefix rewrite and the NGF SnippetsFilter reference, and templates/authup/httproute.yaml is deleted. Everything authup-related now lives under `authup:` in the upstream vocabulary instead of being split across two namespaces. authup.server.publicUrl is the single source of truth for the public address; it defaults to the shared Hub hostname + /auth and this chart reads it back for the Hub UI. server.route.enabled is a plain boolean the subchart cannot tpl-render, so authup does not follow global.flameHub.gatewayApi.enabled - it is enabled per environment. Reported upstream as authup/helm#13. BREAKING CHANGE: global.flameHub.authup.* is gone. Gateway API routing for authup moves to authup.server.route (enabled, hostnames, parentRefs, matches, filters) and the public URL to authup.server.publicUrl.

matchesdefaults to a PathPrefix/match. Route hostnames are derived from the public URL's origin andauthup.urlOrigindrops the path, so the chart's own documented sub-path topology emitted a route that quietly claimed the whole hostname:With both services on one shared host, the two routes tie on every precedence rule and the alphabetical tie-break sends

PathPrefixmatch from the publicUrl path. authup serves at/and expects the proxy to strip the prefix (server-core's html adapter: "The reverse proxy is expected to strip the prefix before the request reaches authup"). A derived match without aURLRewritewould replace a working catch-all with a 404 storm.route.extraRules. Gateway API merges rules across HTTPRoutes attached to the same listener by match specificity, so a second route through the chart's existing tpl-renderedextraDeployalready covers it.
