Types

type API 

type API struct {
	// AdvertiseAddress sets the IP address for the API server to advertise.
	AdvertiseAddress string
	// ControlPlaneEndpoint sets a stable IP address or DNS name for the control plane; it
	// can be a valid IP address or a RFC-1123 DNS subdomain, both with optional TCP port.
	// In case the ControlPlaneEndpoint is not specified, the AdvertiseAddress + BindPort
	// are used; in case the ControlPlaneEndpoint is specified but without a TCP port,
	// the BindPort is used.
	// Possible usages are:
	// e.g. In an cluster with more than one control plane instances, this field should be
	// assigned the address of the external load balancer in front of the
	// control plane instances.
	// e.g.  in environments with enforced node recycling, the ControlPlaneEndpoint
	// could be used for assigning a stable DNS to the control plane.
