1.准备dashboard镜像
[root@hdss7-200 harbor]# docker pull k8scn/kubernetes-dashboard-amd64:v1.8.3
[root@hdss7-200 harbor]# docker images|grep dashboard
[root@hdss7-200 harbor]# docker tag fcac9aa03fd6 harbor.od.com/public/dashboard:v1.8.3
[root@hdss7-200 harbor]# docker push harbor.od.com/public/dashboard:v1.8.3
2.创建资源配置清单
在hdss7-200.host.com上
[root@hdss7-200 harbor]# mkdir -p /data/k8s-yaml/dashboard && cd /data/k8s-yaml/dashboard

3.应用资源配置清单
[root@hdss7-21 containers]# kubectl apply -f http://k8s-yaml.od.com/dashboard/rbac.yaml
[root@hdss7-21 containers]# kubectl apply -f http://k8s-yaml.od.com/dashboard/dp.yaml
[root@hdss7-21 containers]# kubectl apply -f http://k8s-yaml.od.com/dashboard/svc.yaml
[root@hdss7-21 containers]# kubectl apply -f http://k8s-yaml.od.com/dashboard/ingress.yaml
4.查看创建的资源
[root@hdss7-21 containers]# kubectl get pods -n kube-system
[root@hdss7-21 containers]# kubectl get svc -n kube-system
[root@hdss7-21 containers]# kubectl get ingress -n kube-system
5.解析域名
[root@hdss7-11 conf.d]# vi /var/named/od.com.zone
$ORIGIN od.com.
$TTL 600 ; 10 minutes
@ IN SOA dns.od.com. dnsadmin.od.com. (
2020042602 ; serial //前滚一个序列号
10800 ; refresh (3 hours)
900 ; retry (15 minutes)
604800 ; expire (1 week)
86400 ; minimum (1 day)
)
NS dns.od.com.
$TTL 60 ; 1 minute
dns A 10.4.7.11
harbor A 10.4.7.200
k8s-yaml A 10.4.7.200
traefik A 10.4.7.10
dashboard A 10.4.7.10
[root@hdss7-11 conf.d]# systemctl restart named
6.浏览器访问
http://dashboard.od.com/
7.令牌命令行获取方式
kubectl get secret -n kube-system
kubectl describe secret kubernetes-dashboard-admin-token-xxxxx -n kube-system
