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 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
