ZookeeperReconciler reconciles a Zookeeper object

func (*ZookeeperReconciler) Reconcile

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

Reconcile is part of the main kubernetes reconciliation loop, which aims to move the current state of the cluster closer to the desired state. It is essential for the controller's reconciliation loop to be idempotent. By following the Operator pattern you will create Controllers which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster. Breaking this recommendation goes against the design principles of controller-runtime. and may lead to unforeseen consequences such as resources becoming stuck and requiring manual intervention.

func (*ZookeeperReconciler) SetupWithManager

func (r *ZookeeperReconciler) SetupWithManager(mgr ctrl.Manager) error

SetupWithManager sets up the controller with the Manager. Note that the Deployment will be also watched in order to ensure its desirable state on the cluster
