本文是基于kubeasz 进行部署安装，将部署心得记录下来。可以查看原文地址：

1. 创建一个yaml文件。eg：dashboard.yaml。复制一下代码

nodePort: 30065
selector:
k8s-app: kubernetes-dashboard
type: NodePort
本文使用NodePort方式部署，所以需要修改加粗部分的端口号，端口应该大于30000
2. 创建dashboard 服务
kubectl apply -f ./dashboard.yaml
查看dashboard是否创建
kubectl get svc -n kube-system
3.使用https://Ip:30065，由于本文使用的是30065端口。可以根据实际情况修改。
如果使用chrome浏览器提示安全问题，可以是用Firefox。登录页面可以跳过验证或者添加token，如果跳过验证可能会有权限问题。
本文使用token的方式,创建一个account.yaml文件：
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kube-system ---
apiVersion: rbac.authorization.k8s.io/v1
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
kubectl apply -f ./account.yaml
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
输入的文件中复制"token：" 以后的内容到登录页面的TOKEN中，然后就登录成功。
