前言：

接上一篇负载均衡部署（3）部署UI界面

部署环境

负载均衡
Nginx1:192.168.13.128/24
Nginx2:192.168.13.129/24
Master节点
master1:192.168.13.131/24 kube-apiserver kube-controller-manager kube-scheduler etcd

1，在master01上创建dashboard

[root@master01 ~]# cd k8s/
[root@master01 k8s]# mkdir dashboard  ##创建工作目录
[root@master01 k8s]# cd dashboard/
[root@master01 dashboard]# rz -E  ##上传dashboard的yaml文件
[root@master01 dashboard]# ls
dashboard-configmap.yaml   ##配置应用
dashboard-rbac.yaml         ##授权访问api
dashboard-service.yaml    ##发布应用
dashboard-controller.yaml  ##控制器
dashboard-secret.yaml       ##安全加密
k8s-admin.yaml     ##生成令牌
[root@master01 dashboard]# kubectl create -f dashboard-rbac.yaml  ##创建api授权
[root@master01 dashboard]# kubectl create -f dashboard-secret.yaml   ##创建安全加密
[root@master01 dashboard]# kubectl create -f dashboard-configmap.yaml  ##创建配置
[root@master01 dashboard]# kubectl create -f dashboard-controller.yaml   ##创建应用
[root@master01 dashboard]# kubectl create -f dashboard-service.yaml   ##创建发布
[root@master01 dashboard]# kubectl get pods -n kube-system  
##查看创建在指定的kube-system命名空间
NAME                                    READY   STATUS    RESTARTS   AGE
kubernetes-dashboard-65f974f565-xwhcb   1/1     Running   0          2m31s
[root@master01 dashboard]# kubectl get pods,svc -n kube-system  ##查看如何访问
NAME                                        READY   STATUS    RESTARTS   AGE
pod/kubernetes-dashboard-65f974f565-xwhcb   1/1     Running   0          4m55s

NAME                           TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
service/kubernetes-dashboard   NodePort   10.0.0.119           443:30001/TCP   4m51s

2，用浏览器访问node节点ip（Google浏览器无法访问的问题）

##更多工具——开发者工具——security

3，进行自签证书

[root@master01 dashboard]# vim dashboard-cert.sh   ##创建证书脚本文件
cat > dashboard-csr.json <

4，重新用浏览器访问node1节点地址

5，生成令牌，进行使用UI界面

---

 vim k8s-admin.yaml  ##证书生成的yaml配置文件
 apiVersion: v1
kind: ServiceAccount
metadata:
	name: dashboard-admin
	namespace: kube-system
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
	name: dashboard-admin
subjects:
	- kind: ServiceAccount
		name: dashboard-admin
		namespace: kube-system
roleRef:
	kind: ClusterRole
	name: cluster-admin
	apiGroup: rbac.authorization.k8s.io

---

[root@master01 dashboard]# kubectl create -f k8s-admin.yaml  ##生成令牌
[root@master01 dashboard]# kubectl get secret -n kube-system  ##保存令牌
NAME                               TYPE                                  DATA   AGE
dashboard-admin-token-489x2        kubernetes.io/service-account-token   3      2m2s
[root@master01 dashboard]# kubectl describe secret dashboard-admin-token-489x2 -n kube-system
##查看令牌

6，利用令牌进行登录

##成功访问到UI界面
