Dashboard 支持 Kubeconfig 和 Token 两种认证方式，我们这里选择Token认证方式登录：
创建admin-user.yaml文件
vim admin-user.yaml

---    
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user-token
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user-token
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user-token
  namespace: kube-system

说明：上面创建了一个叫admin-user-toen的服务账号，并放在kube-system命名空间下，并将cluster-admin角色绑定到admin-user-toen账户，这样admin-user-toen账户就有了管理员的权限。默认情况下，kubeadm创建集群时已经创建了cluster-admin角色，我们直接绑定即可.

[root@elk-master ~]# kubectl describe secret -n kube-system $(kubectl get secret  -n kube-system |grep admin-user-token| awk '{print $1}')

使用Linux vfio将Nvidia GPU透传给QEMU虚拟机

Linux 上虚拟机 GPU 透传需要使用 vfio 的方式。主要是因为在 vfio 方式下对虚拟设备的权限和 DMA 隔离上做的更好。但是这么做也有个缺点，这个物理设备在主机和其他虚拟机都不能使用了。 qemu 直接使用物理设备本身命令行是很简单的，关键在于事先在主机上对系统、内核和物理设备的一些配置。单纯从 qemu 的命令行来看，其实和普通虚拟机启动就差了最后那个-device的选项。这
