Functions

func ConvertKubePortProtocol

func ConvertKubePortProtocol(port *discoveryv1.DestinationSpec_KubeService_KubeServicePort) string

ConvertKubePortProtocol converts protocol of k8s Service port to application level protocol exported for use in enterprise

func ResolutionForEndpointIpVersions

func ResolutionForEndpointIpVersions(
	workloadEntries []*networkingv1alpha3spec.WorkloadEntry,
) (networkingv1alpha3spec.ServiceEntry_Resolution, error)

Workaround for Istio issue where ipv6 addresses are supplied to Envoy incorrectly: https://github.com/envoyproxy/envoy/issues/10489#issuecomment-606290733. If any endpoints have an ipv6 address, set the resolution to STATIC, else, set the resolution to DNS. exported for use in enterprise

Types

type Translator

type Translator interface {

	// Translate translates a ServiceEntry, VirtualService and DestinationRule for the given Destination using the data in status.AppliedFederation.
	// returns nil if no VirtualService or DestinationRule is required for the Mesh (i.e. if no VirtualService/DestinationRule features are required, such as subsets).
	// Errors caused by invalid user config will be reported using the Reporter.
	Translate(
		in input.LocalSnapshot,
		destination *discoveryv1.Destination,
		reporter reporting.Reporter,
	) (
		[]*networkingv1alpha3.ServiceEntry,
		[]*networkingv1alpha3.VirtualService,
		[]*networkingv1alpha3.DestinationRule,
	)
}

the Federation translator translates a Destination into a ServiceEntry, VirtualService, and DestinationRule

func NewTranslator

func NewTranslator(
	ctx context.Context,
	virtualServiceTranslator virtualservice.Translator,
