参考github

1 获取dashboard image镜像

[root@master1 manifests]# docker pull registry.cn-hangzhou.aliyuncs.com/rsqlh/kubernetes-dashboard:v1.10.1
[root@master1 manifests]# docker tag registry.cn-hangzhou.aliyuncs.com/rsqlh/kubernetes-dashboard:v1.10.1 k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
[root@master1 manifests]# docker rmi registry.cn-hangzhou.aliyuncs.com/rsqlh/kubernetes-dashboard:v1.10.1

2 在线应用yaml文件（或者wget至本地应用）

[root@master1 manifests]# kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created

# 查看pod
[root@master1 manifests]# kubectl get pods -n kube-system
kubernetes-dashboard-57df4db6b-p9sm8      1/1     Running   0          15s

3 patch打补丁，修改类型为NodePort，暴露端口

[root@master1 manifests]# kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.96.0.10      <none>        53/UDP,53/TCP   49d
kubernetes-dashboard   ClusterIP   10.98.192.109   <none>        443/TCP         8m43s
[root@master1 manifests]# kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kube-system
service/kubernetes-dashboard patched
[root@master1 manifests]# kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.96.0.10      <none>        53/UDP,53/TCP   49d
kubernetes-dashboard   NodePort    10.98.192.109   <none>        443:32031/TCP   10m

4 浏览器测试访问
在这里插入图片描述

1 token令牌认证登录

（1）创建serviceaccount

[root@master1 pki]# kubectl create serviceaccount dashboard-admin -n kube-system
serviceaccount/dashboard-admin created
[root@master1 pki]# kubectl get sa -n kube-system
NAME                                 SECRETS   AGE
......
dashboard-admin                      1         13s
......

（2）把serviceaccount绑定在clusteradmin，授权serviceaccount用户具有整个集群的访问管理权限

[root@master1 pki]# kubectl create clusterrolebinding dashboard-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
clusterrolebinding.rbac.authorization.k8s.io/dashboard-cluster-admin created

（3）获取serviceaccount的secret信息，可得到token（令牌）的信息

[root@master1 pki]# kubectl get secret -n kube-system
NAME                                             TYPE                                  DATA     
......    
daemon-set-controller-token-t4jhj                kubernetes.io/service-account-token   3   
......
[root@master1 pki]# kubectl describe secret dashboard-admin-token-lg48q -n kube-system
Name:         dashboard-admin-token-lg48q
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboard-admin

（4）通过patch暴露端口

[root@master1 pki]# kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kube-system
service/kubernetes-dashboard patched
[root@master1 pki]# kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.96.0.10    <none>        53/UDP,53/TCP   49d
kubernetes-dashboard   NodePort    10.99.54.66   <none>        443:32639/TCP   10m

（5）浏览器访问登录，把token粘贴进去登录即可

2 kubeconfig配置文件登录

创建一个只能对default名称空间有权限的serviceaccount

[root@master1 pki]# kubectl create serviceaccount def-ns-admin -n default

[root@master1 pki]# kubectl create rolebinding def-ns-admin --clusterrole=admin --serviceaccount=default:def-ns-admin

这种情况下的权限较小，用token登陆后只能对default名称空间有权限
