-  IngressClassName is the name of the IngressClass cluster resource. The associated IngressClass defines which controller will implement the resource. This replaces the deprecated `kubernetes.io/ingress.class` annotation. For backwards compatibility, when that annotation is set, it must be given precedence over this field. The controller may emit a warning if the field and annotation have different values. Implementations of this API should ignore Ingresses without a class specified. An IngressClass resource may be marked as default, which can be used to set a default value for this field. For more information, refer to the IngressClass documentation.
+  IngressClassName is the name of an IngressClass cluster resource. Ingress controller implementations use this field to know whether they should be serving this Ingress resource, by a transitive connection (controller -> IngressClass -> Ingress resource). Although the `kubernetes.io/ingress.class` annotation (simple constant name) was never formally defined, it was widely supported by Ingress controllers to create a direct binding between Ingress controller and Ingress resources. Newly created Ingress resources should prefer using the field. However, even though the annotation is officially deprecated, for backwards compatibility reasons, ingress controllers should still honor that annotation if present.

-  ingressClassName 是 IngressClass 集群资源的名称。关联的 Ingress 类定义了将实际实现 Ingress 资源的控制器。
-  这一字段将取代不再推荐使用的 `kubernetes.io/ingress.class` 注解。
-  为了向后兼容，当设置了该注解时，注解必须优先于此字段。如果字段和注解具有不同的值，控制器可能会发出警告。
-  此 API 的实现应忽略未指定类的 Ingress 资源。IngressClass 资源可被标记为 default，用来设置此字段的默认值。
