Functions

func EnsureResources

func EnsureResources(ctx context.Context, client ctrlruntimeclient.Client, data nodePortProxyData) error

func FrontLoadBalancerServiceCreator

func FrontLoadBalancerServiceCreator(data *resources.TemplateData) reconciling.NamedServiceCreatorGetter

FrontLoadBalancerServiceCreator returns the creator for the LoadBalancer that fronts apiserver and openVPN when using exposeStrategy=LoadBalancer.

Types

type ExposeType

type ExposeType int

ExposeType defines the strategy used to expose the service.

	// NodePortType is the default ExposeType which creates a listener for each
	// NodePort.
	NodePortType ExposeType = iota
	// SNIType configures Envoy to route TLS streams based on SNI
	// without terminating them.
	SNIType
	// TunnelingType configures Envoy to terminate the tunnel and stream the
	// data to the destination.
	// The only supported tunneling technique at the moment in HTTP/2 Connect.
	TunnelingType
