Types

type HostResolver

type HostResolver interface {
	HasSynced() bool
	Subset() []corev1.EndpointSubset
}

HostResolver is used for getting endpoint subsets with resolved IPs.

type Provider

type Provider interface {
	HasSynced() bool
	Start(ctx context.Context) error
	WithCallback(onUpdate func())
	HostResolver
}

Provider allows to start and attach callbacks for a specific host resolution updates.

func CreateForCluster

func CreateForCluster(restConfig *rest.Config, log logr.Logger) (Provider, error)

CreateForCluster tries to use the hostname and port from the client to create the provider. If that fails, then tries to use the KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT environment variable. If that fails it fallbacks to NoOpProvider().

func NewNoOpProvider

func NewNoOpProvider() Provider

NewNoOpProvider returns a no-op Provider.

func NewProvider

func NewProvider(host string, port string, log logr.Logger, resync time.Duration) Provider

NewProvider returns a Provider for a specific host and port with resync indicating how often the hostname resolution is happening.
