關于如何搭建基于docker的Kubernetes環境，請看筆者另一片博客： https://my.oschina.net/u/3559870/blog/1031428

插件說明

完成使用Kubeadm搭建Kubernetes(docker)之后，Kubernetes實際已經搭建成功～但是頻繁操作命令行界面是會崩潰的好嗎！！所以在Kubernetes 1.2版本后新增了Kube Dashboard，我們就可以在瀏覽器愉快的通過點 點 點操作啦。 ##功能說明 ## create：上傳json或者yaml的方式新建resource，同kubectl create -f delete：刪除副本(Replication Controllers) modify：修改副本數(replicas) query：查詢相關信息，同kubectl get 通過web-ui+上述功能，我們就能基本脫離命令行界面了！

安裝步驟

此時已經完成kubernetes的搭建。 我們將dashboard以靜態Pod的方式運行在Master Node上。

cd /etc/kubernetes/manifests

此目錄是已有的靜態Pod的yaml文件，我們創建kubernetes-dashboard.yaml文件

創建文件kubernetes-dashboard-rbac.yaml文件

kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1beta1 metadata:name: dashboard-admin roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin subjects: - kind: ServiceAccountname: defaultnamespace: kube-system

創建dashboard、dashboard-rbac resource

kubectl create -f kubernetes-dashboard-rbac.yml kubectl create -f kubernetes-dashboard.yaml

創建成功結果如下所示

[root@kube-master manifests]# kubectl create -f dashboard-rbac.yaml clusterrolebinding "dashboard-admin" created [root@kube-master manifests]# kubectl create -f dashboard.yaml serviceaccount "kubernetes-dashboard" created clusterrolebinding "kubernetes-dashboard" created deployment "kubernetes-dashboard" created service "kubernetes-dashboard" created

查詢dashboard運行的端口

kubectl describe --namespace kube-system service kubernetes-dashboard [root@kube-master manifests]# kubectl describe --namespace kube-system service kubernetes-dashboard Name: kubernetes-dashboard Namespace: kube-system Labels: app=kubernetes-dashboard Annotations: <none> Selector: app=kubernetes-dashboard Type: NodePort IP: 10.110.236.54 Port: <unset> 80/TCP NodePort: <unset> 30989/TCP Endpoints: 10.244.0.16:9090 Session Affinity: None Events: <none>

NodePort就是我們要訪問的端口啦！快快打開瀏覽器輸入{master-ip}:{node-port}吧！
