Types

type HostResolver

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

HostResolver is used for getting endpoint subsets with resolved IPs.

type Provider

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

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

func CreateForCluster

func CreateForCluster(client kubernetes.Interface, 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.
