func NewCertificateUpdater

func NewCertificateUpdater(addressWatcher AddressWatcher, getter StateServingInfoGetter,
	configGetter EnvironConfigGetter, setter StateServingInfoSetter, certChanged chan params.StateServingInfo,
) worker.Worker

Types

type AddressWatcher

type AddressWatcher interface {
	WatchAddresses() state.NotifyWatcher

func (*CertificateUpdater) SetUp

func (c *CertificateUpdater) SetUp() (watcher.NotifyWatcher, error)

SetUp is defined on the NotifyWatchHandler interface.

func (*CertificateUpdater) TearDown

func (c *CertificateUpdater) TearDown() error

TearDown is defined on the NotifyWatchHandler interface.

type EnvironConfigGetter

type EnvironConfigGetter interface {
	EnvironConfig() (*config.Config, error)
}

EnvironConfigGetter is an interface that is provided to NewCertificateUpdater which can be used to get environment config.

type StateServingInfoGetter

	StateServingInfo() (params.StateServingInfo, bool)
}

StateServingInfoGetter is an interface that is provided to NewCertificateUpdater whose StateServingInfo method will be invoked to get state serving info.

type StateServingInfoSetter

type StateServingInfoSetter func(info params.StateServingInfo, done <-chan struct{}) error
