【问题描述】：

我正在使用 traefik 2.2 在 kubernetes v1.18 集群中公开 kubernetes 仪表板。这是我机器中的 traefik IngressRoute 配置：

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: kubernetes-dashboard-route
  namespace: default
spec:
  entryPoints:
    - websecure
  routes:
    - match: Host(`kubernete.dolphin.com`) 
      kind: Rule
      services:
        - name: kubernetes-dashboard
          port: 443

traefik 使用hostNetwork:true 配置并监听主机的 8000 和 8443 端口。当我在集群中使用服务 ip 访问 kubernetes 仪表板时，它显示如下：

[root@k8smaster ~]# curl -k https://10.20.57.188:443

它告诉我 kubernetes 仪表板工作正常。但是当我从本地机器访问 kubernetes 仪表板时：

[root@k8smaster ~]# curl -k --header 'Host:kubernete.dolphin.com' https://192.168.31.30:8443
404 page not found

我应该怎么做才能让它成功？我正在使用此命令安装 traefik：

helm install traefik traefik/traefik

没有错误日志：

【问题讨论】：

分享来自 traefik pod 的日志
没有来自 traefik pod@ArghyaSadhu 的日志

标签： kubernetes traefik

【解决方案1】：

我在本地实验环境部署我的kubernetes，所以禁用traefik中的TLS检查修复这个问题，在Traefik中添加配置：

containers:
- name: traefik
    args:
      - '--serversTransport.insecureSkipVerify=true'

然后使用它来检查是否成功：

[root@k8smaster ~]# curl -k --header "Host: kubernetes.dolphin.com" http://192.168.31.30:8443
