k8s（11）：k8s安装（十）部署Dashboard

1. 下载文件

#创建目录(master-1节点)
[root@master-1 ~]# mkdir /root/dashboard
[root@master-1 ~]# kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

#修改端口
#修改为nodeport端口50000
#注意镜像地址无法下载, 使用另外的镜像替换
mirrorgooglecontainers/kubernetes-dashboard-amd64:v1.10.1
[root@master-1 ~]# sed -i '/targetPort:/a\ \ \ \ \ \ nodePort: 50000\n\ \ type: NodePort' kubernetes-dashboard.1.10.yaml

2. 部署

[root@master-1 dashboard]# kubectl apply -f kubernetes-dashboard.1.10.yaml

#查看服务端口
[root@master-1 dashboard]# kubectl get services -n kube-system
NAME                   TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                  AGE
coredns                ClusterIP   10.0.0.2     <none>        53/UDP,53/TCP,9153/TCP   19d
kubelet                ClusterIP   None         <none>        10250/TCP                12d
kubernetes-dashboard   NodePort    10.0.0.218   <none>        443:50000/TCP            16s

#创建用户授权
[root@master-1 dashboard]# kubectl create serviceaccount  dashboard-admin -n kube-system
[root@master-1 dashboard]# kubectl create clusterrolebinding  \
dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin

3. 获取Token

#获取token
[root@master-1 ~]# kubectl describe secrets -n kube-system $(kubectl -n kube-system get secret | awk '/dashboard-admin/{print $1}')

4. 登录系统

#如果之前有安装过其他的版本的dashboard, 那么切换node节点IP访问
