func WithStatsReporter

func WithStatsReporter(ctx context.Context, sr StatsReporter) context.Context

WithStatsReporter attaches the given StatsReporter to the provided context in the returned context.

type Base

type Base struct {
	// KubeClientSet allows us to talk to the k8s for core APIs
	KubeClientSet kubernetes.Interface

	// EventingClientSet allows us to configure Eventing objects
	EventingClientSet clientset.Interface

	// LegacyClientSet allows us to configure Legacy Eventing objects
	LegacyClientSet legacyclientset.Interface

	// ApiExtensionsClientSet allows us to configure k8s API extension objects.
	ApiExtensionsClientSet apiextensionsclientset.Interface

	// DynamicClientSet allows us to configure pluggable Build objects
	DynamicClientSet dynamic.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.

func NewBase

func NewBase(ctx context.Context, controllerAgentName string, cmw configmap.Watcher) *Base

NewBase instantiates a new instance of Base implementing the common & boilerplate code between our reconcilers.

type Measurement

type Measurement int

type Measurements

type Measurements struct {
	ReadyLatencyStat *stats.Int64Measure
	ReadyCountStat   *stats.Int64Measure
}

type StatKey

type StatKey struct {
	ReadyLatencyKey string
	ReadyCountKey   string
}

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 GetStatsReporter

func GetStatsReporter(ctx context.Context) StatsReporter

GetStatsReporter attempts to look up the StatsReporter on a given context. It may return nil if none is found.

func NewStatsReporter

func NewStatsReporter(reconciler string) (StatsReporter, error)

NewStatsReporter creates a reporter for reconcilers' metrics
