type CompletedConfig

type CompletedConfig struct {
	*Config
}

CompletedConfig is the completed configuration for GenericAPIServer.

func (CompletedConfig) New

New returns a new instance of GenericAPIServer from the given config.

type Config

type Config struct {
	SecureServing   *SecureServingInfo
	InsecureServing *InsecureServingInfo
	Jwt             *JwtInfo
	Mode            string
	Middlewares     []string
	Healthz         bool
