Types

type Constructor

type Constructor func(params Parameters) Decorator

type Decorator

type Decorator interface {
	// unique identifier for decorator
	DecoratorName() string
}

Decorators modify the output VirtualService corresponding to the input TrafficTarget.

type Factory

type Factory interface {
	// return a set of decorators built from the given snapshot.
	MakeDecorators(params Parameters) []Decorator
}

the decorator Factory initializes Translator decorators on each reconcile

func NewFactory

func NewFactory() Factory

type Parameters

type Parameters struct {
	ClusterDomains hostutils.ClusterDomainRegistry
	Snapshot       input.Snapshot
}

parameters for initializing decorators

type RegisterField

type RegisterField func(fieldPtr, val interface{}) error

type TrafficPolicyDestinationRuleDecorator

type TrafficPolicyDestinationRuleDecorator interface {
	Decorator

	ApplyTrafficPolicyToDestinationRule(
		appliedPolicy *discoveryv1alpha2.TrafficTargetStatus_AppliedTrafficPolicy,
		service *discoveryv1alpha2.TrafficTarget,
		output *networkingv1alpha3spec.DestinationRule,
		registerField RegisterField,
	) error
}

a TrafficPolicyDestinationRuleDecorator modifies the DestinationRule based on a TrafficPolicy which applies to the TrafficTarget.

type TrafficPolicyVirtualServiceDecorator

type TrafficPolicyVirtualServiceDecorator interface {
	Decorator

	ApplyTrafficPolicyToVirtualService(
		appliedPolicy *discoveryv1alpha2.TrafficTargetStatus_AppliedTrafficPolicy,
		trafficTarget *discoveryv1alpha2.TrafficTarget,
		sourceMeshInstallation *discoveryv1alpha2.MeshSpec_MeshInstallation,
		output *networkingv1alpha3spec.HTTPRoute,
		registerField RegisterField,
	) error
}

A TrafficPolicyVirtualServiceDecorator modifies the VirtualService based on a TrafficPolicy which applies to the TrafficTarget.

If sourceMeshInstallation is specified, hostnames in the translated VirtualService will use global FQDNs if the trafficTarget exists in a different cluster from the specified mesh (i.e. is a federated traffic target). Otherwise, assume translation for cluster that the trafficTarget exists in and use local FQDNs.

type VirtualTrafficTargetEntryDecorator

type VirtualTrafficTargetEntryDecorator interface {
	Decorator

	ApplyVirtualMeshToServiceEntry(
		appliedVirtualMesh *discoveryv1alpha2.MeshStatus_AppliedVirtualMesh,
		service *discoveryv1alpha2.TrafficTarget,
		output *networkingv1alpha3spec.ServiceEntry,
		registerField RegisterField,
	) error
}

a VirtualTrafficTargetEntryDecorator modifies the ServiceEntry based on a VirtualMesh which applies to the TrafficTarget.
