### 基础环境 ###

拥有一个完美运行的kubernetes1.13.4集群并已经部署过dashboard，可参考我的部署文章创建自己的集群。

### 部署步骤 ###

1.  编写部署需要的yaml文件
    
     *  traefik-rbac.yaml
        
            ---
            kind: ClusterRole

                resources:
                - ingresses/status
                verbs:
                - update

                      serviceName: traefik-web-ui
                      servicePort: web
2.  执行命令完成相关部署
    
        $ kubectl create -f traefik-rbac.yaml
        
        $ kubectl create -f traefik-deployment.yaml
        
        $ kubectl create -f ui.yaml
3.  验证部署结果
    
        $ kubectl get pod,svc --all-namespaces | grep traefik
        
        kube-system     pod/traefik-ingress-controller-8c8b85bbc-6bpb4   1/1     Running   0          66m
        kube-system     service/traefik-ingress-service   NodePort       10.110.48.244    <none>        80:32575/TCP,8080:31639/TCP   66m
        kube-system     service/traefik-web-ui            ClusterIP      10.103.88.103    <none>        80/TCP                        57m
4.  访问traefik的UI界面
    
    访问 `http://<node_ip>:<node_port>/dashboard/#/`
    
    UI界面的端口是8080
