Functions

func MakeDestinationRuleSubsetsForFailoverService

func MakeDestinationRuleSubsetsForFailoverService(
	failoverService *discoveryv1alpha2.MeshStatus_AppliedFailoverService,
	allTrafficTargets discoveryv1alpha2sets.TrafficTargetSet,
) []*networkingv1alpha3spec.Subset

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

func MakeDestinationRuleSubsetsForTrafficTarget

func MakeDestinationRuleSubsetsForTrafficTarget(
	trafficTarget *discoveryv1alpha2.TrafficTarget,
	allTrafficTargets discoveryv1alpha2sets.TrafficTargetSet,
	failoverServices v1alpha2sets.FailoverServiceSet,
	sourceClusterName string,
) []*networkingv1alpha3spec.Subset

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

func MakeFederatedSubsetLabel

func MakeFederatedSubsetLabel(clusterName string) map[string]string

clusterName corresponds to the cluster name for the federated traffic target.

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 TrafficTarget 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,
	trafficTargets discoveryv1alpha2sets.TrafficTargetSet,
	failoverServices v1alpha2sets.FailoverServiceSet,
) *trafficShiftDecorator
