Types ¶
type Reconciler ¶
type Reconciler struct {
TargetClient client.Client
Config resourcemanagerconfigv1alpha1.NetworkPolicyControllerConfig
Recorder events.EventRecorder
CacheSynced bool
// contains filtered or unexported fields
}
Reconciler reconciles Service objects and creates NetworkPolicy objects.
func (*Reconciler) AddToManager ¶
func (r *Reconciler) AddToManager(ctx context.Context, mgr manager.Manager, targetCluster cluster.Cluster) error
AddToManager adds Reconciler to the given manager.
func (*Reconciler) EventHandlerForNamespace ¶
func (r *Reconciler) EventHandlerForNamespace(log logr.Logger) handler.EventHandler
EventHandlerForNamespace returns an EventHandler that enqueues reconcile requests for Services associated with the given Namespace object.
func (*Reconciler) EventHandlerForPod ¶
func (r *Reconciler) EventHandlerForPod(log logr.Logger) handler.EventHandler
EventHandlerForPod returns an EventHandler that tracks seen network policy label keys per namespace, only enqueueing services when a namespace's key coverage changes. This avoids redundant lookups during cache warmup where many pods per namespace would trigger identical service mappings (cf. https://github.com/kubernetes-sigs/controller-runtime/issues/3466). The event handler functions are called sequentially by the informer's processorListener goroutine (cf. https://github.com/kubernetes/client-go/blob/v0.35.3/tools/cache/shared_informer.go), so no synchronization is needed for the tracking map.
func (*Reconciler) IngressPredicate ¶ added in v1.67.0
func (r *Reconciler) IngressPredicate() predicate.Predicate
IngressPredicate returns a predicate which filters UPDATE events on Ingresses such that only updates to the rules are relevant.
func (*Reconciler) MapIngressToServices ¶ added in v1.67.0
MapIngressToServices is a handler.MapFunc for mapping a Ingresses to all referenced services.
func (*Reconciler) MapNetworkPolicyToService ¶ added in v1.67.0
func (r *Reconciler) MapNetworkPolicyToService(_ context.Context, obj client.Object) []reconcile.Request
MapNetworkPolicyToService is a handler.MapFunc for mapping a NetworkPolicy to the referenced service.
func (*Reconciler) MapVirtualServiceToServices ¶
func (r *Reconciler) MapVirtualServiceToServices(_ context.Context, obj client.Object) []reconcile.Request
MapVirtualServiceToServices is a handler.MapFunc for mapping a VirtualService to all referenced services in its routes.
func (*Reconciler) PodPredicate ¶
func (r *Reconciler) PodPredicate() predicate.Predicate
PodPredicate returns a predicate which filters for pods with `networking.resources.gardener.cloud/to-*` labels.
func (*Reconciler) Reconcile ¶
func (r *Reconciler) Reconcile(ctx context.Context, request reconcile.Request) (reconcile.Result, error)
Reconcile performs the main reconciliation logic.
func (*Reconciler) ServicePredicate ¶
func (r *Reconciler) ServicePredicate() predicate.Predicate
ServicePredicate returns a predicate which filters UPDATE events on services such that only updates to the deletion timestamp, the port list, the pod label selector, or well-known annotations are relevant.
func (*Reconciler) VirtualServicePredicate ¶
func (r *Reconciler) VirtualServicePredicate() predicate.Predicate
VirtualServicePredicate returns a predicate which filters UPDATE events on VirtualServices such that only updates to the hosts, gateways, http, TLS or TCP routes are relevant.
