所有东西都在BareMetal上，负载均衡器位于集群外部。
这是一个简单的haproxy配置，只需检查80端口(Worker ip(

我使用Helm安装nginx入口控制器，一切正常

以简单的方式部署nginx，效果良好
kubectl create deploy nginx --image=nginx:1.18
kubectl scale deploy/nginx --replicas=6
kubectl expose deploy/nginx --type=NodePort --port=80
之后，我决定创建ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: tektutor-ingress
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /

rules:
- host: "tektutor.training.org"
http:
paths:
- pathType: Prefix
path: "/nginx"
backend:
service:
name: nginx
port:
number: 80
工作良好
kubectl describe ingress tektutor-ingress

一切都很好，当我尝试卷曲时，任何ip都可以curl (192.168.133.241:80,192.168.226.104:80,192.168.226.105:80 + 3 more...)
现在我尝试添加主机
10.0.76.201 tektutor.training.org
这是我的主ip，在这里添加主ip正确吗？当我尝试curl tektutor.training.org不工作时
你能解释一下我最后一步有什么问题吗？我把IP设置错了？还是怎样谢谢
我希望我已经把所有的东西都写得很详尽
我曾经这个导师介质安装nginx入口控制器
TL；DR
输入如下所示的haproxy后端配置值，而不是您提供的值：
30659而不是8032160而不是443(如果需要(
更多解释：
NodePort在特定的端口集上工作(默认值：30000-32767(，在这种情况下，它分配了：
30659用于入口nginx控制器端口8032160用于入口nginx控制器端口443
这意味着每一个试图从外部访问集群的请求都需要联系此端口(30…(。
