type DefaultWatchdogClient ¶

type DefaultWatchdogClient struct{}

DefaultWatchdogClient implements the WatchdogClient interface using the actual systemd daemon functions.

func (*DefaultWatchdogClient) SdNotify ¶

func (d *DefaultWatchdogClient) SdNotify(unsetEnvironment bool) (bool, error)

type Option ¶

type Option func(*healthChecker)

Option defines optional parameters for initializing the healthChecker structure.

func WithExtendedCheckers ¶

func WithExtendedCheckers(checkers []healthz.HealthChecker) Option

func WithWatchdogClient ¶

func WithWatchdogClient(watchdog WatchdogClient) Option

type WatchdogClient ¶

type WatchdogClient interface {
	SdWatchdogEnabled(unsetEnvironment bool) (time.Duration, error)
	SdNotify(unsetEnvironment bool) (bool, error)
