Google cloud platform 无法创建gcp入口-同步期间出错：运行后端同步例程时出错：googleapi:获取HTTP响应代码404，正文：未找到

我正在尝试一个简单的gke入门。 仿效

吊舱已启动并运行，服务处于活动状态。当我创建入口时，我会

我找不到问题的根源。有没有关于去哪里找的建议

我已检查群集加载项和权限

httploadbalanced已启用

看起来您缺少默认入口控制器的默认后端（L7-HTTTP LoadBalancer）。从我观察到的情况来看，当您在GKE集群中启用了Istio插件时，它不会部署（Istio有自己的默认入口/出口网关）

请验证它是否已在群集中启动并运行：

kubectl get pod -n kube-system | grep l7-default-backend

这篇文章的作者最终发现，这个问题只有在集群使用引导时才会存在。

您的GKE集群中是否配置了任何其他入口控制器（如nginx入口）？您是否自行为“我的入口”资源创建了“kubernetes.io/ingres.class:gce”注释，还是自动创建的？它是入口定义的一部分<代码>apiVersion:extensions/v1beta1种类：入口元数据：名称：我的入口注释：kubernetes.io/ingres.class:“gce”没有其他入口控制器。注释是入口定义的一部分。使用/不使用相同的结果进行了尝试。它存在，但是没有看到任何日志

rg-dev-europe-west4-1>kubectl get pod-n kube system | grep l7 default backend l7-default-backend-7ff48cffd7-rk4mq 1/1运行0 1h

在loadbalancer pod内是否观察到任何错误？（kubectl日志l7-default-backend-7ff48cffd7-rk4mq）请在下面找到gce入口故障排除指南的链接。不幸的是，我没有看到任何日志，继续四处挖掘，谢谢。我忘了提到最重要的事情，这个GKE教程中的ingress示例对我来说很好。请尝试创建以下入口资源，仅使用基于原始清单文件示例的单路径声明（对于我来说，loadbalancer后端启动需要几分钟）。输出：你好，世界！版本：2.0.0主机名：hello-world-deployment-5cfbc486f-295hn问题似乎在我创建集群的方式上。如果我使用console创建集群，那么ingress可以正常工作。如果使用pulumi构建集群，则会失败。
