	RoleBinding    rbacv1.RoleBinding
	Created        bool
}

type StatefulSetReconciler

type StatefulSetReconciler struct {
	client.Client
	Scheme   *runtime.Scheme
	Recorder record.EventRecorder

	SyncContainerImage string
	SyncClusterRole    string
	RequeueAfter       time.Duration
}

StatefulSetReconciler reconciles a StatefulSet object

func (*StatefulSetReconciler) Reconcile

func (r *StatefulSetReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error)

Reconcile is the main work loop, reacting to changes in statefulsets and initiating resizing of StatefulSets.

func (*StatefulSetReconciler) SetupWithManager
