Functions

func GatewayServiceNamespace

func GatewayServiceNamespace(ingressGateways []config.Gateway, gatewayName string) (string, error)

GatewayServiceNamespace returns the namespace of the gateway service that the `Gateway` object with name `gatewayName` is associated with.

func GetHTTPServer

func GetHTTPServer(gateway *v1alpha3.Gateway) *v1alpha3.Server

GetHTTPServer gets the HTTP `Server` from `Gateway`.

func GetSecrets

func GetSecrets(ci *v1alpha1.ClusterIngress, secretLister corev1listers.SecretLister) (map[string]*corev1.Secret, error)

GetSecrets gets the all of the secrets referenced by the given ClusterIngress, and returns a map whose key is the a secret namespace/name key and value is pointer of the secret.

func GetServers

func GetServers(gateway *v1alpha3.Gateway, ci *v1alpha1.ClusterIngress) []v1alpha3.Server

GetServers gets the `Servers` from `Gateway` that belongs to the given ClusterIngress.

func MakeHTTPServer

func MakeHTTPServer(httpProtocol network.HTTPProtocol) *v1alpha3.Server

MakeHTTPServer creates a HTTP Gateway `Server` based on the HTTPProtocol configureation.

func MakeIngressVirtualService

func MakeIngressVirtualService(ci *v1alpha1.ClusterIngress, gateways []string) *v1alpha3.VirtualService

MakeIngressVirtualService creates Istio VirtualService as network programming for Istio Gateways other than 'mesh'.

func MakeMeshVirtualService

func MakeMeshVirtualService(ci *v1alpha1.ClusterIngress) *v1alpha3.VirtualService

MakeMeshVirtualService creates Istio VirtualService as network programming for Istio network mesh.

func MakeSecrets

func MakeSecrets(ctx context.Context, originSecrets map[string]*corev1.Secret, ci *v1alpha1.ClusterIngress) []*corev1.Secret

MakeSecrets makes copies of the origin Secrets under the namespace of Istio gateway service.

func MakeServers

func MakeServers(ci *v1alpha1.ClusterIngress, gatewayServiceNamespace string, originSecrets map[string]*corev1.Secret) ([]v1alpha3.Server, error)

MakeServers creates the expected Gateway `Servers` based on the given ClusterIngress.

func MakeVirtualServices

func MakeVirtualServices(ci *v1alpha1.ClusterIngress, gateways []string) []*v1alpha3.VirtualService

MakeVirtualServices creates Istio VirtualServices as network programming.

These VirtualService specifies which Gateways and Hosts that it applies to, as well as the routing rules.

func SecretRef

func SecretRef(namespace, name string) corev1.ObjectReference

SecretRef returns the ObjectReference of a secret given the namespace and name of the secret.

func SortServers

func SortServers(servers []v1alpha3.Server) []v1alpha3.Server

SortServers sorts `Server` according to its port name.

func UpdateGateway

func UpdateGateway(gateway *v1alpha3.Gateway, want []v1alpha3.Server, existing []v1alpha3.Server) *v1alpha3.Gateway

UpdateGateway replaces the existing servers with the wanted servers.

func VirtualServiceNamespace

func VirtualServiceNamespace(_ *v1alpha1.ClusterIngress) string

VirtualServiceNamespace gives the namespace of the child VirtualServices for a given ClusterIngress.
