ResourcePlacementStatus condition reasons and message formats

Variables

var (

Types

type Reconciler

type Reconciler struct {
	// the informer contains the cache for all the resources we need.
	InformerManager informer.Manager

	// RestMapper is used to convert between gvk and gvr on known resources.
	RestMapper meta.RESTMapper

	// Client is used to update objects which goes to the api server directly.
	Client client.Client

	// UncachedReader is the uncached read-only client for accessing Kubernetes API server; in most cases client should
	// be used instead, unless consistency becomes a serious concern.
	// It's only needed by v1beta1 APIs.
	UncachedReader client.Reader

	// ResourceConfig contains all the API resources that we won't select based on allowed or skipped propagating APIs option.
	ResourceConfig *utils.ResourceConfig

	// SkippedNamespaces contains the namespaces that we should not propagate.
	SkippedNamespaces map[string]bool

	Recorder record.EventRecorder

	Scheme *runtime.Scheme
}

Reconciler reconciles a cluster resource placement object

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(ctx context.Context, key controller.QueueKey) (ctrl.Result, error)

func (*Reconciler) ReconcileV1Alpha1

func (r *Reconciler) ReconcileV1Alpha1(ctx context.Context, key controller.QueueKey) (ctrl.Result, error)

ReconcileV1Alpha1 reconciles v1aplha1 APIs.
