Functions

func MakeDestinationRuleSubsetsForDestination

func MakeDestinationRuleSubsetsForDestination(
	destination *discoveryv1.Destination,
	allDestinations discoveryv1sets.DestinationSet,
	sourceClusterName string,
) []*networkingv1alpha3spec.Subset

make all the necessary subsets for the destination rule for the given destination. traverses all the applied traffic policies to find subsets matching this destination

func MakeDestinationRuleSubsetsForVirtualDestination

func MakeDestinationRuleSubsetsForVirtualDestination(
	virtualDestination *v1beta1.VirtualDestination,
	allTrafficTargets discoveryv1sets.DestinationSet,
) []*networkingv1alpha3spec.Subset

make all the necessary subsets for the destination rule for the given VirtualDestination. traverses all the applied traffic policies to find subsets matching this VirtualDestination

func MakeFederatedSubsetLabel

func MakeFederatedSubsetLabel(clusterName string) map[string]string

clusterName corresponds to the cluster name for the federated Destination.

NOTE(ilackarms): we use these labels to support federated subsets. the values don't actually matter; but the subset names should match those on the DestinationRule for the Destination in the remote cluster. based on: https://istio.io/latest/blog/2019/multicluster-version-routing/#create-a-destination-rule-on-both-clusters-for-the-local-reviews-service

func NewTrafficShiftDecorator

func NewTrafficShiftDecorator(
	clusterDomains hostutils.ClusterDomainRegistry,
	destinations discoveryv1sets.DestinationSet,
	virtualDestinations v1beta1sets.VirtualDestinationSet,
) *trafficShiftDecorator
