基于上篇文档安装
主节点：
安装kubenet-dashboard发现会报错
kubectl apply -f http://mirror.faasx.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
ed/kubernetes-dashboard.yaml
可以先下载这个 dashboard.yaml
wget http://mirror.faasx.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
修改一下：讲Deployment的apiversion改成 apps/v1 #不支持以前的版本
[root@k8s-master ~]# cat kubernetes-dashboard.yaml

1.创建服务账号
首先创建一个叫admin-user的服务账号，并放在kube-system名称空间下：
# admin-user.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kube-system执行kubectl create命令：
kubectl create -f admin-user.yaml
2.绑定角色
默认情况下，kubeadm创建集群时已经创建了admin角色，我们直接绑定即可：
#admin-user-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
name: admin-user
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: admin-user
namespace: kube-system执行kubectl create命令：
kubectl create -f admin-user-role-binding.yaml
3.获取Token
现在我们需要找到新创建的用户的Token，以便用来登录dashboard：
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
复制token登陆系统
