Functions

func FilterEndpoints

func FilterEndpoints(
	_ context.Context,
	writeNamespace string,
	kubeEndpoints []*kubev1.Endpoints,
	services []*kubev1.Service,
	pods []*kubev1.Pod,
	upstreams map[*core.ResourceRef]*kubeplugin.UpstreamSpec,
) (v1.EndpointList, []string, []string)

FilterEndpoints computes the endpoints for Gloo from the given Kubernetes endpoints, services, and Gloo upstreams. It is exported to provide an injection point into our existing EDS solution for the Gloo K8s Gateway integration. It returns the endpoints, warnings, and errors.

func NewPlugin

func NewPlugin(kube kubernetes.Interface, kubeCoreCache corecache.KubeCoreCache) plugins.Plugin

func UpdateUpstream

func UpdateUpstream(original, desired *v1.Upstream) (didChange bool, err error)

func UpstreamName

func UpstreamName(serviceNamespace, serviceName string, servicePort int32) string

Types

type Epkey

type Epkey struct {
	Address     string
	Port        uint32
	Name        string
