Types ¶
type NodeMaintenanceReconciler ¶
type NodeMaintenanceReconciler struct {
client.Client
Scheme *runtime.Scheme
// contains filtered or unexported fields
}
NodeMaintenanceReconciler reconciles a NodeMaintenance object
func (*NodeMaintenanceReconciler) Reconcile ¶
func (r *NodeMaintenanceReconciler) 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 NodeMaintenance 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@v0.9.2/pkg/reconcile
func (*NodeMaintenanceReconciler) SetupWithManager ¶
func (r *NodeMaintenanceReconciler) SetupWithManager(mgr ctrl.Manager) error
SetupWithManager sets up the controller with the Manager.
