	flinkCluster *v1beta1.FlinkCluster) metav1.OwnerReference

Converts the FlinkCluster as owner reference for its child resources.

Types

type ClusterReconciler

type ClusterReconciler struct {
	// contains filtered or unexported fields
}

ClusterReconciler takes actions to drive the observed state towards the desired state.

type ClusterStateObserver

type ClusterStateObserver struct {
	// contains filtered or unexported fields
}

ClusterStateObserver gets the observed state of the cluster.

type ClusterStatusUpdater

type ClusterStatusUpdater struct {
	// contains filtered or unexported fields
}

ClusterStatusUpdater updates the status of the FlinkCluster CR.

type FlinkClusterHandler

type FlinkClusterHandler struct {
	// contains filtered or unexported fields
}

FlinkClusterHandler holds the context and state for a reconcile request.

type FlinkClusterReconciler

type FlinkClusterReconciler struct {
	Client client.Client
	Log    logr.Logger
	Mgr    ctrl.Manager
}

FlinkClusterReconciler reconciles a FlinkCluster object

func (*FlinkClusterReconciler) Reconcile

func (reconciler *FlinkClusterReconciler) Reconcile(
	request ctrl.Request) (ctrl.Result, error)
