在master01上操作

1、创建dashborad工作目录

[root@localhost k8s]# mkdir dashboard

2、拷贝官方文件

[root@localhost k8s]# cd dashboard/
[root@localhost dashboard]# ls            
dashboard-configmap.yaml   dashboard-rbac.yaml    dashboard-service.yaml
dashboard-controller.yaml  dashboard-secret.yaml  k8s-admin.yaml
##相关文件用途：
dashboard-configmap.yaml：配置应用
dashboard-rbac.yaml：授权访问api，web界面
dashboard-service.yaml：访问应用
dashboard-controller.yaml：控制器
dashboard-secret.yaml：安全、加密
k8s-admin.yaml：生成令牌

3、组件创建

[root@localhost dashboard]# kubectl create -f dashboard-rbac.yaml
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
[root@localhost dashboard]# kubectl create -f dashboard-secret.yaml
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-key-holder created
[root@localhost dashboard]# kubectl create -f dashboard-configmap.yaml
configmap/kubernetes-dashboard-settings created
[root@localhost dashboard]# kubectl create -f dashboard-controller.yaml
serviceaccount/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
[root@localhost dashboard]# kubectl create -f dashboard-service.yaml
service/kubernetes-dashboard created

4、完成后查看创建在指定的kube-system命名空间下

[root@localhost dashboard]# kubectl get pods -n kube-system
NAME                                    READY   STATUS    RESTARTS   AGE
kubernetes-dashboard-65f974f565-8b88b   1/1     Running   0          2m56s

5、查看如何访问

[root@localhost dashboard]# kubectl get pods,svc -n kube-system
NAME                                        READY   STATUS    RESTARTS   AGE
pod/kubernetes-dashboard-65f974f565-8b88b   1/1     Running   0          4m4s

NAME                           TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
service/kubernetes-dashboard   NodePort   10.0.0.26            443:30001/TCP   3m50s

6、访问nodeIP就可以访问

浏览器访问https://192.168.35.101:30001/

7、google浏览器无法访问的问题，解决办法如下

（1）证书自签

[root@localhost dashboard]# vim dashboard-cert.sh

cat > dashboard-csr.json <


（2）生成证书
[root@localhost dashboard]# bash dashboard-cert.sh /root/k8s/k8s-cert/
2020/02/08 19:55:08 [INFO] generate received request
2020/02/08 19:55:08 [INFO] received CSR
2020/02/08 19:55:08 [INFO] generating key: rsa-2048
2020/02/08 19:55:09 [INFO] encoded CSR
2020/02/08 19:55:09 [INFO] signed certificate with serial number 702272605681507929850954926507995861695177925647
2020/02/08 19:55:09 [WARNING] This certificate lacks a "hosts" field. This makes it unsuitable for
websites. For more information see the Baseline Requirements for the Issuance and Management
of Publicly-Trusted Certificates, v.1.1.6, from the CA/Browser Forum (https://cabforum.org);
specifically, section 10.2.3 ("Information Requirements").
secret "kubernetes-dashboard-certs" deleted
secret/kubernetes-dashboard-certs created

[root@localhost dashboard]# ls
dashboard-cert.sh          dashboard-csr.json   dashboard-secret.yaml
dashboard-configmap.yaml   dashboard-key.pem    dashboard-service.yaml
dashboard-controller.yaml  dashboard.pem        k8s-admin.yaml
dashboard.csr              dashboard-rbac.yaml
（3）dashboard-controller.yaml 增加证书两行，然后apply
[root@localhost dashboard]# vim dashboard-controller.yaml

        args:
          # PLATFORM-SPECIFIC ARGS HERE
          - --auto-generate-certificates
          - --tls-key-file=dashboard-key.pem
          - --tls-cert-file=dashboard.pem
（4）重新部署
[root@localhost dashboard]# kubectl apply -f dashboard-controller.yaml
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
serviceaccount/kubernetes-dashboard configured
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
deployment.apps/kubernetes-dashboard configured
（5）再次进行访问：https://192.168.35.101:30001/
8、生成令牌
[root@localhost dashboard]# kubectl create -f k8s-admin.yaml
serviceaccount/dashboard-admin created
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created
9、保存
[root@localhost dashboard]# kubectl get secret -n kube-system
NAME                               TYPE                                  DATA   AGE
dashboard-admin-token-ls8r7        kubernetes.io/service-account-token   3      73s
default-token-685rn                kubernetes.io/service-account-token   3      6h36m
kubernetes-dashboard-certs         Opaque                                11     16m
kubernetes-dashboard-key-holder    Opaque                                2      41m
kubernetes-dashboard-token-drpwb   kubernetes.io/service-account-token   3      40m
10、查看令牌

[root@localhost dashboard]# kubectl describe secret dashboard-admin-token-ls8r7 -n kube-system
Name:         dashboard-admin-token-ls8r7
Namespace:    kube-system
Labels:       
Annotations:  kubernetes.io/service-account.name: dashboard-admin
              kubernetes.io/service-account.uid: f283296f-4a6b-11ea-b063-000c29148af8

11、复制令牌进行登录
主界面：
进入容器：点击容器组——》点击运行命令——》进入容器

在node节点访问IP：
[root@localhost cfg]# curl 172.17.45.2
