Types ¶
type Base ¶
type Base struct { // KubeClientSet allows us to talk to the k8s for core APIs KubeClientSet kubernetes.Interface // DynamicClientSet allows us to configure pluggable Build objects DynamicClientSet dynamic.Interface KafkaClientSet clientset.Interface // ConfigMapWatcher allows us to watch for ConfigMap changes. ConfigMapWatcher configmap.Watcher // Recorder is an event recorder for recording Event resources to the // Kubernetes API. Recorder record.EventRecorder // StatsReporter reports reconciler's metrics. StatsReporter StatsReporter // Sugared logger is easier to use but is not as performant as the // raw logger. In performance critical paths, call logger.Desugar() // and use the returned raw logger instead. In addition to the // performance benefits, raw logger also preserves type-safety at // the expense of slightly greater verbosity. Logger *zap.SugaredLogger }
Base implements the core controller logic, given a Reconciler.
type Measurements ¶
type Measurements struct { ReadyLatencyStat *stats.Int64Measure ReadyCountStat *stats.Int64Measure }
type Options ¶
type Options struct { KubeClientSet kubernetes.Interface DynamicClientSet dynamic.Interface KafkaClientSet clientset.Interface Recorder record.EventRecorder StatsReporter StatsReporter ConfigMapWatcher *configmap.InformedWatcher Logger *zap.SugaredLogger ResyncPeriod time.Duration StopChannel <-chan struct{} }
Options defines the common reconciler options. We define this to reduce the boilerplate argument list when creating our controllers.
func NewOptionsOrDie ¶
func NewOptionsOrDie(cfg *rest.Config, logger *zap.SugaredLogger, stopCh <-chan struct{}) Options
func (Options) GetTrackerLease ¶
GetTrackerLease returns a multiple of the resync period to use as the duration for tracker leases. This attempts to ensure that resyncs happen to refresh leases frequently enough that we don't miss updates to tracked objects.
type StatsReporter ¶
type StatsReporter interface { // ReportReady reports the time it took a resource to become Ready. ReportReady(kind, namespace, service string, d time.Duration) error }
StatsReporter reports reconcilers' metrics.
func NewStatsReporter ¶
func NewStatsReporter(reconciler string) (StatsReporter, error)
NewStatsReporter creates a reporter for reconcilers' metrics
