Question

我正在尝试从入口规则中删除具有后端的路径，但无法完全正常工作。

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，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， AdditionalProperties = {}），AdditionalProperties = {}），路径= / myservice / 6， AdditionalProperties = {}）]

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:

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

  Normal   Success              16m   public  Successfully applied ingress resource.

所以我的问题是：如何使用kubernetes-client-java动态删除Ingress中的路径？我使用kubernetes-client创建了规则，所以我知道它在理论上是可行的，只是无法让它再次删除。

您可以这样删除igress：

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

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