安装Kubernetes-Dashboard插件

关于如何搭建基于docker的Kubernetes环境，请看笔者另一片博客：
http://blog.csdn.net/jinzili777/article/details/73498476

插件说明

完成使用Kubeadm搭建Kubernetes(docker)之后，Kubernetes实际已经搭建成功～但是频繁操作命令行界面是会崩溃的好吗！！所以在Kubernetes 1.2版本后新增了Kube Dashboard，我们就可以在浏览器愉快的通过点 点 点操作啦。

功能说明

create：上传json或者yaml的方式新建resource，同kubectl create -f
delete：删除副本(Replication Controllers)
modify：修改副本数(replicas)
query：查询相关信息，同kubectl get
通过web-ui+上述功能，我们就能基本脱离命令行界面了！

安装步骤

此时已经完成kubernetes的搭建。
我们将dashboard以静态Pod的方式运行在Master Node上。

cd /etc/kubernetes/manifests

此目录是已有的静态Pod的yaml文件，我们创建kubernetes-dashboard.yaml文件

创建文件kubernetes-dashboard-rbac.yaml文件

kind: ClusterRoleBindingapiVersion: rbac.authorization.k8s.io/v1beta1metadata:  name: dashboard-adminroleRef:  apiGroup: rbac.authorization.k8s.io  kind: ClusterRole  name: cluster-admin subjects:- kind: ServiceAccount  name: default  namespace: kube-system

创建dashboard、dashboard-rbac resource

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

创建成功结果如下所示

[root@kube-master manifests]# kubectl create -f dashboard-rbac.yamlclusterrolebinding "dashboard-admin" created[root@kube-master manifests]# kubectl create -f dashboard.yamlserviceaccount "kubernetes-dashboard" createdclusterrolebinding "kubernetes-dashboard" createddeployment "kubernetes-dashboard" createdservice "kubernetes-dashboard" created

查询dashboard运行的端口

kubectl describe --namespace kube-system service kubernetes-dashboard

[root@kube-master manifests]# kubectl describe --namespace kube-system service kubernetes-dashboardName:           kubernetes-dashboardNamespace:      kube-systemLabels:         app=kubernetes-dashboardAnnotations:        <none>Selector:       app=kubernetes-dashboardType:           NodePortIP:         10.110.236.54Port:           <unset> 80/TCPNodePort:       <unset> 30989/TCPEndpoints:      10.244.0.16:9090Session Affinity:   NoneEvents:         <none>

NodePort就是我们要访问的端口啦！快快打开浏览器输入{master-ip}:{node-port}吧！
