Kubernetes 负载均衡器

Question

我设置了我的树莓派集群并安装了 metallb。 我正在运行以下 Wordpress 服务。 我很困惑为什么我不能通过浏览器或 wget 进程让它工作

pi@master:~ $ kubectl get svc
NAME         TYPE           CLUSTER-IP      EXTERNAL-IP    PORT(S)        AGE
kubernetes   ClusterIP      10.96.0.1       <none>         443/TCP        6d3h
mysql        ClusterIP      None            <none>         3306/TCP       41m
wordpress    LoadBalancer   10.101.63.209   192.168.1.50   80:32499/TCP   4m35s

当我尝试对我的网站进行 wget 时，它会继续尝试通过端口 30820 输出 go

我在这里做错了什么？

pi@master:~ $ wget 192.168.1.50
--2020-04-05 03:29:56--  http://192.168.1.50/
Connecting to 192.168.1.50:80... connected.

Connecting to 192.168.1.50:30820... failed: No route to host.

这是我的部署。 这看起来好吗？

Answer 1

可能是您的 Wordpress 设置，这意味着重定向。 MetalLB 和 k8s 服务都没有重定向功能，因为它们都在网络级别上工作。
