kubernetes1.13.4部署traefik

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
     apiVersion: rbac.authorization.k8s.io/v1beta1
     metadata:
       name: traefik-ingress-controller
     rules:
       - apiGroups:
           - ""
         resources:
           - services
           - endpoints
           - secrets
         verbs:
           - get
           - list
           - watch
       - apiGroups:
           - extensions
         resources:
           - ingresses
         verbs:
           - get
           - list
           - watch
       - apiGroups:
         - extensions
         resources:
         - ingresses/status
         verbs:
         - update
     ---
     kind: ClusterRoleBinding
     apiVersion: rbac.authorization.k8s.io/v1beta1
     metadata:
       name: traefik-ingress-controller
     roleRef:
       apiGroup: rbac.authorization.k8s.io
       kind: ClusterRole
       name: traefik-ingress-controller
     subjects:
     - kind: ServiceAccount
       name: traefik-ingress-controller
       namespace: kube-system
     
     

   • traefik-deployment.yaml

     ---
     apiVersion: v1
     kind: ServiceAccount
     metadata:
       name: traefik-ingress-controller
       namespace: kube-system
     ---
     kind: Deployment
     apiVersion: extensions/v1beta1
     metadata:
       name: traefik-ingress-controller
       namespace: kube-system
       labels:
         k8s-app: traefik-ingress-lb
     spec:
       replicas: 1
       selector:
         matchLabels:
           k8s-app: traefik-ingress-lb
       template:
         metadata:
           labels:
             k8s-app: traefik-ingress-lb
             name: traefik-ingress-lb
         spec:
           serviceAccountName: traefik-ingress-controller
           terminationGracePeriodSeconds: 60
           containers:
           - image: traefik
             name: traefik-ingress-lb
             ports:
             - name: http
               containerPort: 80
             - name: admin
               containerPort: 8080
             args:
             - --api
             - --kubernetes
             - --logLevel=INFO
     ---
     kind: Service
     apiVersion: v1
     metadata:
       name: traefik-ingress-service
       namespace: kube-system
     spec:
       selector:
         k8s-app: traefik-ingress-lb
       ports:
         - protocol: TCP
           port: 80
           name: web
         - protocol: TCP
           port: 8080
           name: admin
       type: NodePort
     

   • ui.yaml

     ---
     apiVersion: v1
     kind: Service
     metadata:
       name: traefik-web-ui
       namespace: kube-system
     spec:
       selector:
         k8s-app: traefik-ingress-lb
       ports:
       - name: web
         port: 80
         targetPort: 8080
     ---
     apiVersion: extensions/v1beta1
     kind: Ingress
     metadata:
       name: traefik-web-ui
       namespace: kube-system
     spec:
       rules:
       - host: traefik-ui.minikube
         http:
           paths:
           - path: /
             backend:
               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
