Types

type Reconciler

type Reconciler struct {
	GardenClient   client.Client
	RuntimeClient  client.Client
	Config         config.NetworkPolicyControllerConfiguration
	Resolver       hostnameresolver.HostResolver
	ResolverUpdate <-chan event.GenericEvent
	SeedNetworks   gardencore.SeedNetworks
}

Reconciler implements the reconcile.Reconcile interface for namespace reconciliation.

func (*Reconciler) AddToManager

func (r *Reconciler) AddToManager(mgr manager.Manager, gardenCluster, seedCluster cluster.Cluster) error

AddToManager adds Reconciler to the given manager.

func (*Reconciler) ClusterPredicate

func (r *Reconciler) ClusterPredicate() predicate.Predicate

ClusterPredicate is a predicate which returns 'true' when the network CIDRs of a shoot cluster change.

func (*Reconciler) IsKubernetesEndpoint

func (r *Reconciler) IsKubernetesEndpoint() predicate.Predicate

IsKubernetesEndpoint returns a predicate which evaluates if the object is the kubernetes endpoint.

func (*Reconciler) MapObjectToName

func (r *Reconciler) MapObjectToName(_ context.Context, _ logr.Logger, _ client.Reader, obj client.Object) []reconcile.Request

MapObjectToName is a mapper function which maps an object to its name.

func (*Reconciler) MapObjectToNamespace

func (r *Reconciler) MapObjectToNamespace(_ context.Context, _ logr.Logger, _ client.Reader, obj client.Object) []reconcile.Request

MapObjectToNamespace is a mapper function which maps an object to its namespace.

func (*Reconciler) MapToNamespaces

func (r *Reconciler) MapToNamespaces(ctx context.Context, log logr.Logger, _ client.Reader, _ client.Object) []reconcile.Request

MapToNamespaces is a mapper function which returns requests for all shoot namespaces + garden namespace + istio-system namespace.

func (*Reconciler) NetworkPolicyPredicate

func (r *Reconciler) NetworkPolicyPredicate() predicate.Predicate

NetworkPolicyPredicate is a predicate which returns true in case the network policy name matches with one of those managed by this reconciler.

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(ctx context.Context, request reconcile.Request) (reconcile.Result, error)

Reconcile reconciles namespace in order to create some central network policies.
