Functions

func MakeDestinationRuleSubsets

func MakeDestinationRuleSubsets(
	requiredSubsets []*discoveryv1.RequiredSubsets,
) []*networkingv1alpha3spec.Subset

func MakeDestinationRuleSubsetsForDestination

func MakeDestinationRuleSubsetsForDestination(
	destination *discoveryv1.Destination,
	sourceCluster 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,
) []*networkingv1alpha3spec.Subset

exported for use in enterprise

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 exported for use in enterprise

func SubsetName

func SubsetName(labels map[string]string) string

used in DestinationRule translator as well

func TranslateRequestMatchers

func TranslateRequestMatchers(
	requestMatchers []*v1.HttpMatcher,
	sourceSelectors []*commonv1.WorkloadSelector,
) []*networkingv1alpha3spec.HTTPMatchRequest

TranslateRequestMatchers translates request matchers to Istio. Only provide sourceNamespace and sourceLabels for translation of in-mesh VirtualServices.

func TranslateWeightedDestination

func TranslateWeightedDestination(
	weightedDest *networkingv1.WeightedDestination,
	sourceCluster string,
	destinations discoveryv1sets.DestinationSet,
	virtualDestinations v1beta1sets.VirtualDestinationSet,
	clusterDomains hostutils.ClusterDomainRegistry,
) (*networkingv1alpha3spec.HTTPRouteDestination, error)
