}

IKubernetesManager is an interface depicting the controller's interaction with the Kubernetes API.

type RedisClusterReconciler

type RedisClusterReconciler struct {
	KubernetesManager IKubernetesManager
	Scheme            *runtime.Scheme
}

RedisClusterReconciler reconciles a RedisCluster object

func (*RedisClusterReconciler) Reconcile

func (r *RedisClusterReconciler) 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. TODO(user): Modify the Reconcile function to compare the state specified by the RedisCluster object against the actual cluster state, and then perform operations to make the cluster state reflect the state specified by the user.

For more details, check Reconcile and its Result here: - https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.14.1/pkg/reconcile

func (*RedisClusterReconciler) RequeueError

func (r *RedisClusterReconciler) RequeueError(ctx context.Context, message string, err error) (ctrl.Result, error)

func (*RedisClusterReconciler) SetupWithManager

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

SetupWithManager sets up the controller with the Manager.
