Functions

func ControllerLive

func ControllerLive() healthz.HealthChecker

func HTTPBackendAvailable

func HTTPBackendAvailable(u *url.URL) healthz.HealthChecker

HTTPBackendAvailable returns a healthz check that verifies a backend responds to a GET to the provided URL with 2xx or 3xx response.

func HasSynced

func HasSynced(routerPtr **templateplugin.TemplatePlugin) (healthz.HealthChecker, error)

HasSynced returns a healthz check that verifies the router has been synced at least once. routerPtr is a pointer because it may not yet be defined (there's a chicken-and-egg problem with when the health checker and router object are set up).

func ProcessRunning

func ProcessRunning(stopCh <-chan struct{}) healthz.HealthChecker

ProcessRunning returns a healthz check that returns true as long as the provided stopCh is not closed.

func ProxyProtocolHTTPBackendAvailable

func ProxyProtocolHTTPBackendAvailable(u *url.URL) healthz.HealthChecker

ProxyProtocolHTTPBackendAvailable returns a healthz check that verifies a backend supporting the HAProxy PROXY protocol responds to a GET to the provided URL with 2xx or 3xx response.
