Types

type Controller

type Controller struct {
	// Name is used to uniquely identify a Controller in tracing, logging and monitoring.  Name is required.
	Name string

	// MaxConcurrentReconciles is the maximum number of concurrent Reconciles which can be run. Defaults to 1.
	MaxConcurrentReconciles int

	// Reconciler is a function that can be called at any time with the Name / Namespace of an object and
	// ensures that the state of the system matches the state specified in the object.
	// Defaults to the DefaultReconcileFunc.
	Do reconcile.Reconciler

	// Client is a lazily initialized Client.  The controllerManager will initialize this when Start is called.
	Client client.Client

	// Scheme is injected by the controllerManager when controllerManager.Start is called
	Scheme *runtime.Scheme

	// MakeQueue constructs the queue for this controller once the controller is ready to start.
	// This exists because the standard Kubernetes workqueues start themselves immediately, which
	// leads to goroutine leaks if something calls controller.New repeatedly.
	MakeQueue func() workqueue.RateLimitingInterface

	// Queue is an listeningQueue that listens for events from Informers and adds object keys to
	// the Queue for processing
	Queue workqueue.RateLimitingInterface

	// SetFields is used to inject dependencies into other objects such as Sources, EventHandlers and Predicates
	SetFields func(i interface{}) error

	// JitterPeriod allows tests to reduce the JitterPeriod so they complete faster
	JitterPeriod time.Duration

	// Started is true if the Controller has been Started
	Started bool

	// Recorder is an event recorder for recording Event resources to the
	// Kubernetes API.
	Recorder record.EventRecorder

	// Log is used to log messages to users during reconciliation, or for example when a watch is started.
	Log logr.Logger
	// contains filtered or unexported fields
