Overview

Package ingestion holds functions that translate from Kubernetes resources into Listener types for storage in the model.

Functions

func GammaHTTPRoutes

func GammaHTTPRoutes(input GammaInput) []model.HTTPListener

GammaHTTPRoutes takes a GammaInput and gives back the associated HTTP Listeners It does not support TLS Routes because GAMMA is only for cleartext config - it is assumed that any TLS will be performed transparently by the underlying implementation in the spec.

func GatewayAPI

func GatewayAPI(input Input) ([]model.HTTPListener, []model.TLSPassthroughListener)

GatewayAPI translates Gateway API resources into a model.

func Ingress

func Ingress(ing networkingv1.Ingress, defaultSecretNamespace, defaultSecretName string, enforcedHTTPS bool, insecureListenerPort, secureListenerPort uint32, defaultRequestTimeout time.Duration) []model.HTTPListener

Ingress translates an Ingress resource to a HTTPListener. This function does not check IngressClass (via field or annotation). It's expected that only relevant Ingresses will have this function called on them.

func IngressPassthrough

func IngressPassthrough(ing networkingv1.Ingress, listenerPort uint32) []model.TLSPassthroughListener

IngressPassthrough translates an Ingress resource with the tls-passthrough annotation to a TLSListener. This function does not check IngressClass (via field or annotation). It's expected that only relevant Ingresses will have this function called on them.

Ingress objects with SSL Passthrough enabled have the following properties:

* must have a host set * rules with paths other than '/' are ignored * default backends are ignored

Types

type GammaInput

type GammaInput struct {
	HTTPRoutes      []gatewayv1.HTTPRoute
	ReferenceGrants []gatewayv1beta1.ReferenceGrant
	Services        []corev1.Service
}

GammaInput is the input for GatewayAPI.

type GatewayClassConfig

type GatewayClassConfig struct {
	// Service is the front-end service configuration for the GatewayClass
	// Normally, this is used to configure the LoadBalancer type service,
	// and mapped to k8s Service object
	Service *ServiceConfig `json:"service,omitempty"`
}

GatewayClassConfig is the struct for GatewayClass parameters The struct is used to unmarshal the ConfigMap data

type Input

type Input struct {
	GatewayClass       gatewayv1.GatewayClass
	GatewayClassConfig *v2alpha1.CiliumGatewayClassConfig

	Gateway         gatewayv1.Gateway
	HTTPRoutes      []gatewayv1.HTTPRoute
	TLSRoutes       []gatewayv1alpha2.TLSRoute
	GRPCRoutes      []gatewayv1.GRPCRoute
	ReferenceGrants []gatewayv1beta1.ReferenceGrant
	Services        []corev1.Service
	ServiceImports  []mcsapiv1alpha1.ServiceImport
}

Input is the input for GatewayAPI.

type ServiceConfig

type ServiceConfig struct {
	// Type is the type of the service (e.g. LoadBalancer, NodePort, ClusterIP).
	// Defaults to LoadBalancer
	Type                          *string  `json:"type,omitempty"`
	ExternalTrafficPolicy         *string  `json:"externalTrafficPolicy,omitempty"`
	LoadBalancerClass             *string  `json:"loadBalancerClass,omitempty"`
	LoadBalancerSourceRanges      []string `json:"loadBalancerSourceRanges,omitempty"`
	IPFamilies                    []string `json:"ipFamilies,omitempty"`
	IPFamilyPolicy                *string  `json:"ipFamilyPolicy,omitempty"`
	AllocateLoadBalancerNodePorts *bool    `json:"allocateLoadBalancerNodePorts,omitempty"`
	TrafficDistribution           *string  `json:"trafficDistribution,omitempty"`
}
