chore: upgrade api7-ingress-controller to 2.2.1

[AlinsRan]

Releases the api7-ingress-controller chart for api7-ingress-controller 2.2.1.

Changes

Item	From	To
charts/ingress-controller chart version	0.1.27	0.1.28
appVersion / deployment.image.tag	2.2.0	2.2.1
adc.image.tag	0.27.1	0.30.2

CRD sync

crds/apisix-crds.yaml is regenerated with kustomize build config/crd at tag 2.2.1, which adds:

• GatewayProxy — spec.provider.controlPlane.auth.caCert, a PEM CA bundle used to verify the control plane TLS certificate instead of the system trust store (feat: support a CA bundle for the control plane connection api7-ingress-controller#447).
• Consumer / PluginConfig / L4RoutePolicy — plugins[].secretRef, which pulls sensitive plugin configuration from a Secret in the same namespace instead of inlining it in config (feat: support secretRef in v1alpha1 plugin configuration api7-ingress-controller#470).

No RBAC, webhook or ConfigMap changes: config/rbac/role.yaml only moved endpoints into the core-group rule that the chart already grants, and the webhook manifests and controller config schema are unchanged between 2.2.0 and 2.2.1. The bundled Gateway API CRDs stay at v1.6.0.

Verification

• kustomize build config/crd at tag 2.1.0 reproduces the previously committed apisix-crds.yaml byte for byte, so the regeneration path is the same one used for earlier releases.
• helm lint charts/ingress-controller and helm template pass; the CRD file parses as 12 CustomResourceDefinition documents with no duplicates.
• helm-docs --chart-search-root=charts produces no changes beyond charts/ingress-controller/README.md.
• Both images resolve: api7/api7-ingress-controller:2.2.1 and ghcr.io/api7/adc:0.30.2.

Summary by CodeRabbit

• New Features

  • Added support for referencing same-namespace Secrets to override plugin configuration values.
  • Added certificate value configuration for Gateway Proxy control-plane connections, with PEM validation.

• Updates

  • Updated the ingress controller release to version 2.2.1.
  • Updated the ADC image to version 0.30.2.
  • Updated the Helm chart to version 0.1.28.

📝 Walkthrough

Walkthrough

The ingress-controller Helm chart now declares updated release and image versions. Its CRDs support Secret-backed plugin configuration overrides and validated GatewayProxy control-plane CA certificates.

Changes

Ingress controller chart update

Layer / File(s)	Summary
CRD configuration schema updates charts/ingress-controller/crds/apisix-crds.yaml	Consumer, L4RoutePolicy, and PluginConfig plugins accept same-namespace Secret references for configuration overrides. GatewayProxy accepts a validated caCert.value.
Chart release and image metadata charts/ingress-controller/Chart.yaml, charts/ingress-controller/values.yaml, charts/ingress-controller/README.md	The chart and application versions change to 0.1.28 and 2.2.1. The ingress-controller image changes to 2.2.1, and the ADC image changes to 0.30.2.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to 4e322

The chart adds CA and Secret-backed plugin configuration fields, but malformed CA values and empty Secret references can be accepted and later cause invalid or ineffective controller configuration. Tightening these CRD validations before merge would prevent avoidable user configuration failures.

Full details: E2e Test Quality Review

Explanation

Blocking: the PR adds CRD behavior for plugins[].secretRef and GatewayProxy.spec.provider.controlPlane.caCert, but it adds no E2E tests. The only related CI test runs ct install, which installs the chart in kind and does not exercise Secret-backed plugin configuration, certificate verification, controller reconciliation, or external service behavior. This does not cover the required end-to-end business flow.

Resolution

Add real-cluster E2E tests for the three plugin CRDs and GatewayProxy. Create the required Secret and custom resources, verify admission and controller reconciliation, and verify the resulting plugin configuration and control-plane TLS behavior through the external service. Include invalid or missing Secret and certificate cases, plus precedence of Secret values over inline configuration. Run these tests in CI.

In `@charts/ingress-controller/crds/apisix-crds.yaml`:
- Around line 3325-3327: The CRD validation for the CA certificate must reject
header-only PEM values. Update the x-kubernetes-validations rule near the
tlsVerify CA field to require both certificate delimiters, while preserving the
existing PEM validation message and downstream complete-certificate validation
behavior.
- Around line 3113-3118: Update the three secretRef schemas at
charts/ingress-controller/crds/apisix-crds.yaml:3113-3118, 3913-3918, and
4391-4396 to remove default: "" from the name property, require name within each
secretRef object, and enforce minLength: 1 (or equivalent CEL validation). Keep
secretRef itself optional.
