使用 java kubernetes-client 从 kubernetes 入口删除路径

Question

我正在尝试从入口规则中删除带有后端的路径，但无法使其正常工作。

这是我尝试删除它的方式：

// get path to delete
Optional<HTTPIngressPath> pathToDelete = kubernetesClient.extensions().ingresses().withName("my-ingress")
    .get()
    .getSpec()
    .getRules()
    .get(0)
    .getHttp()
    .getPaths().stream()
        .filter(path -> path.getBackend().getServiceName().equals(buildServiceNameById(id))).findFirst();

if(!pathToDelete.isPresent()) {
    LOGGER.warn("Couldn't determine ingress path for " + buildServiceNameById(id) + ".");
    return;
}

kubernetesClient.extensions().ingresses().withName("my-ingress")
    .edit()
    .editSpec()
    .editFirstRule()
    .editHttp()
        .removeFromPaths(pathToDelete.get())
    .endHttp()
    .endRule()
    .endSpec()
    .done();

LOGGER.info("Deleted ingress routing " + pathToDelete.toString());

当我查看日志时，我可以看到它找到了路径并输出：

已删除入口路由 可选[HTTPIngressPath(backend=IngressBackend(serviceName=my-service-6, servicePort=IntOrString(IntVal=8080, Kind=null, StrVal=null, 附加属性={})、附加属性={})、 路径=/myservice/6， 附加属性={})]

但是当我描述入口时，我可以看到规则仍然存在：

Name:             my-ingress
Namespace:        default
Address:          someAdress
Default backend:  default-http-backend:80 (<none>)
Rules:

  someHost  
                                                       /                                           admin:8888 (<none>)
                                                       /myservice/6   my-service-6:8080 (<none>)

  Warning  ConfigReloadFailure  21m   public  Failed to apply ingress resource.
  Warning  ConfigReloadFailure  20m   public  Failed to apply ingress resource.
  Normal   Success              18m   public  Successfully applied ingress resource.
  Normal   Success              18m   public  Successfully applied ingress resource.
  Normal   Success              17m   public  Successfully applied ingress resource.
  Normal   Success              16m   public  Successfully applied ingress resource.

所以我的问题是：如何使用 kubernetes-client-java 在 Ingress 中动态删除路径？ 我使用 kubernetes-client 创建了规则，所以我知道它在理论上是有效的，但我无法让它再次删除它。

你可以这样删除 igress：

k8sClient.extensions().ingresses().withName("my-ingress").delete();
