Check if the other resources referenced by an object exist within a webhook

[zhixiongdu027]

I want to check if the other resources referenced by an object exist within a webhook. Could someone please help me complete the logic in the following code example?

Thank you very much.

// SetupWebhookWithManager will setup the manager to manage the webhooks
func (r *Pool) SetupWebhookWithManager(mgr ctrl.Manager) error {
	return ctrl.NewWebhookManagedBy(mgr).
		For(r).
		Complete()
}

var _ webhook.Validator = &Pool{}

func (r *Pool) Validate() error {
	var allErrs field.ErrorList

	model := r.Spec.Model

	/*
		check model is exist here;
	*/

	if len(allErrs) == 0 {
		return nil
	}

	return apierrors.NewInvalid(schema.GroupKind{Group: GroupVersion.Group, Kind: "Pool"}, r.Name, allErrs)
}

// ValidateCreate implements webhook.Validator so a webhook will be registered for the type
func (r *Pool) ValidateCreate() (admission.Warnings, error) {
	poollog.Info("validate create", "name", r.Name)

	// TODO(user): fill in your validation logic upon object creation.
	return nil, r.Validate()
}
