以前，我尝试使用 NodeIP 使其工作入口。 如何让 My First ingress 在裸机 NodeIP 上运行？ 它也不起作用，也许问题和现在一样，我没有正确配置它。
我放弃了这个选项并尝试了 MetalllLB + Ingress
！我在这两种情况下所做的：！我仅在我的工作机器上通过 /etc/hosts 安装了 DNS。
10.0.57.28 cluster.local test.local ingress.example.com dashboard.cluster.local test.cluster.local test.com
带 Helm 的安装 metallb：
helm repo add metallb https://metallb.github.io/metallb
helm install metallb metallb/metallb -f values.yaml
值.yaml
configInline:
address-pools:
- name: default
protocol: layer2
addresses:
- 10.0.57.28-10.0.57.29
使用 Helm¶ 安装入口控制器：
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install ingress-nginx ingress-nginx/ingress-nginx

kubectl 描述 pod ingress-nginx-controller-fd7bb8d66-mvc9d
请帮助我为什么入口不起作用。也许我需要以特定方式自定义 DNS？
Service 和 Ingress 在同一个命名空间中。Ingress Controller 在不同的地方。
我查看入口控制器日志 - 什么都没有，这正常吗？
