feat: support secretRef in v1alpha1 plugin configuration - #470

Conversation
Plugins configured through `apisix.apache.org/v1alpha1` resources had no way to take part of their configuration from a Kubernetes Secret, so credentials such as the `openid-connect` client secret had to be written in plain text in `spec.config`. `ApisixPluginConfig` already supports `secretRef`, which left no equivalent for users on the Gateway API, since `HTTPRoute` filters can only reference `PluginConfig`. Add `secretRef` to the shared v1alpha1 `Plugin` type, so it works in `PluginConfig`, `Consumer` and `L4RoutePolicy`. The data of the referenced Secret is merged over `spec.config`, with each key read as a dot separated path, so `session.secret` sets the `secret` field of the `session` object. Values are merged as strings, so numeric and boolean fields stay in `config`. The Secret must be in the namespace of the object that declares the plugin. A plugin whose Secret is missing is not programmed with a partial configuration; the route or consumer reports the failure in its status. Secrets are indexed and watched, so updating a Secret reprograms the plugins that read it. Sync of apache/apisix-ingress-controller#2855, for apache/apisix-ingress-controller#2832.

Full details: E2e Test Quality ReviewExplanation The PR adds real E2E coverage for the main Secret-backed flows. The HTTPRoute test creates a Kubernetes Secret, PluginConfig, and HTTPRoute, validates Secret-provided body data, nested dot-path header data, preserved inline configuration, and Secret update propagation. The TCPRoute test validates missing-Secret rejection and confirms traffic remains available without partial policy programming. Both tests use real Kubernetes, APISIX, and httpbin services, create resources in per-spec namespaces, use clear names and structured assertions, and check resource-creation errors with Gomega. No hidden test-order dependency, mock overuse, or new concurrency risk is evident. Supporting unit tests cover precedence, nesting, malformed configuration, missing Secrets, and log redaction.

In `@internal/adc/translator/httproute.go`:
- Line 89: Update the logging near the plugins map in the HTTP route translation
flow to avoid logging configuration values derived from Secrets; log only plugin
names or the total plugin count. Keep the plugins map itself available for
configuration use, but ensure the existing log call cannot expose client
secrets, session secrets, tokens, or other plugin configuration fields.
In `@internal/adc/translator/policies.go`:
- Line 266: Update AttachL4RoutePolicyPlugins so a plugin Secret-rendering
failure is returned to its caller instead of being skipped via continue.
Propagate that error through the TCPRoute and TLSRoute translation paths,
preventing StreamRoute emission/programming and reporting the affected route’s
failure.
In `@internal/controller/policies.go`:
- Around line 304-306: Propagate errors from loadPluginSecrets in the
winning-policy handling instead of logging and continuing. Update the TCPRoute,
TLSRoute, and UDPRoute reconciliation paths to return the failure and ensure the
winning policy is not retained in tctx.L4RoutePolicies when plugin Secret
loading fails.

… Secret Three problems with the first version of the feature: - `fillPluginFromExtensionRef` logged the whole rendered plugin map at V(1), which now holds the Secret data. Log the plugin names only. - A plugin whose Secret could not be read was skipped while the route was still programmed, so a route could serve traffic without the auth plugin its filter asks for. Propagate the error out of the extension ref filter so translation of the route fails instead, matching how a malformed v2 plugin config is handled. - `ProcessL4RoutePolicy` only logged the same failure, so an L4 route was programmed without the policy plugins and nothing reported it. Do not attach a policy whose Secrets cannot be read and set its Accepted condition to False with reason Invalid.

The new e2e case failed: after updating the Secret the route kept serving the
value read at the last spec change.
The five Gateway API route controllers set a global
`WithEventFilter(predicate.GenerationChangedPredicate{})`. A Secret has no
generation, so every Secret update compared 0 to 0 and was dropped before it
reached the mapper, which made the Secret watch added in this PR inert. Only the
initial reconcile, driven by the route or PluginConfig spec, ever read the Secret.
Admit Secret events explicitly, the same way ApisixRoute and Consumer already do.

Description
Sync of apache/apisix-ingress-controller#2855, for apache/apisix-ingress-controller#2832
Plugins configured through
apisix.apache.org/v1alpha1resources had no way to take part of their configuration from a Secret, so credentials such as theopenid-connectclient secret had to be written in plain text inspec.config.ApisixPluginConfigalready supportssecretRef, which left no equivalent for users on the Gateway API, sinceHTTPRoutefilters can only referencePluginConfig.This adds
secretRefto the shared v1alpha1Plugintype, so it works inPluginConfig,ConsumerandL4RoutePolicy:Behaviour:
spec.config. Each key is read as a dot separated path, sosession.secretsets thesecretfield of thesessionobject. This matches howApisixPluginConfigalready handlessecretRef.config.I chose this over making
ApisixPluginConfigusable from anExtensionRef, because referencingApisixPluginConfigfrom anHTTPRoutehas an ownership problem:ApisixPluginConfighasspec.ingressClassNameand is reconciled against it, whilePluginConfighas no class field and inherits its owner from the route's Gateway and that Gateway'sGatewayClass. AnHTTPRouteon GatewayClassareferencing anApisixPluginConfigwithingressClassName: bwould leave a choice between ignoringingressClassNameand reportingResolvedRefs=Falseon an object that exists and is owned by another controller.Checklist
