Types

type Config added in v0.3.6 

type Config struct {
	// AnnotationPrefix is the domain prefix for all annotations (e.g., "httproute.controller")
	AnnotationPrefix string
	// DefaultGateway is the default gateway name when not specified in annotations
	DefaultGateway string
	// DefaultGatewayNamespace is the default gateway namespace when not specified in annotations
	DefaultGatewayNamespace string
	// DefaultSectionName is the default gateway listener section name (e.g., "https")
	DefaultSectionName string
}

Config holds the controller configuration

func DefaultConfig added in v0.3.6 

func DefaultConfig() Config

DefaultConfig returns the default configuration

type ServiceReconciler 

type ServiceReconciler struct {
	client.Client
	Scheme *runtime.Scheme
	Config Config
}

ServiceReconciler reconciles a Service object

func (*ServiceReconciler) AnnotationExpose added in v0.3.6 

func (r *ServiceReconciler) AnnotationExpose() string

AnnotationExpose returns the expose annotation key

func (*ServiceReconciler) AnnotationGateway added in v0.3.6 

func (r *ServiceReconciler) AnnotationGateway() string

AnnotationGateway returns the gateway annotation key

func (*ServiceReconciler) AnnotationGatewayNamespace added in v0.3.6 

func (r *ServiceReconciler) AnnotationGatewayNamespace() string

AnnotationGatewayNamespace returns the gateway-namespace annotation key

func (*ServiceReconciler) AnnotationHostname added in v0.3.6 

func (r *ServiceReconciler) AnnotationHostname() string

AnnotationHostname returns the hostname annotation key

func (*ServiceReconciler) AnnotationPort added in v0.3.6 

func (r *ServiceReconciler) AnnotationPort() string

AnnotationPort returns the port annotation key

func (*ServiceReconciler) FinalizerHTTPRoute added in v0.3.6 

func (r *ServiceReconciler) FinalizerHTTPRoute() string

FinalizerHTTPRoute returns the finalizer name

func (*ServiceReconciler) Reconcile 

func (r *ServiceReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error)

Reconcile implements the reconciliation loop for Service resources. It watches Services with the expose annotation and creates/updates/deletes corresponding HTTPRoute and ReferenceGrant resources.

The reconciler follows modern Kubernetes controller best practices: - Level-based triggers (reconciles full state, not just events) - Idempotent operations (safe to call multiple times) - Finalizers for cross-namespace resource cleanup (HTTPRoute) - OwnerReferences for same-namespace resources (ReferenceGrant) - Cross-namespace resource management via ReferenceGrant

func (*ServiceReconciler) SetupWithManager 

func (r *ServiceReconciler) SetupWithManager(mgr ctrl.Manager) error

SetupWithManager sets up the controller with the Manager. Watches Services and owns ReferenceGrant resources. HTTPRoute is NOT owned via OwnerReferences (cross-namespace not supported). Instead, finalizers on Service ensure cleanup of HTTPRoute on deletion. Uses modern controller-runtime patterns: - For() watches the primary resource (Service) - Owns() watches secondary resources for changes (triggers reconciliation of owner)
