2.部署

kubectl apply -f http://k8s-yaml.od.com/dashboard/rbac.yaml
kubectl apply -f http://k8s-yaml.od.com/dashboard/dp.yaml
kubectl apply -f http://k8s-yaml.od.com/dashboard/svc.yaml
kubectl apply -f http://k8s-yaml.od.com/dashboard/ingress.yaml

3.生成dashboard https证书

certs]# (umask 077; openssl genrsa -out dashboard.od.com.key 2048)
certs]# openssl req -new -key dashboard.od.com.key -out dashboard.od.com.csr -subj "/CN=dashboard.od.com/C=CN/ST=BJ/L=Beijing/O=OldboyEdu/OU=ops"
certs]# openssl x509 -req -in dashboard.od.com.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out dashboard.od.com.crt -days 3650
# 查看证书请求文件
certs]# cfssl-certinfo -cert dashboard.od.com.crt

4.配置dashboard nginx代理

conf.d]# cat dashboard.od.com.conf 
server {
    listen       80;
    server_name  dashboard.od.com;

    rewrite ^(.*)$ https://${server_name}$1 permanent;
}
server {
    listen       443 ssl;
    server_name  dashboard.od.com;

    ssl_certificate "certs/dashboard.od.com.crt";
    ssl_certificate_key "certs/dashboard.od.com.key";
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout  10m;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;

    location / {
        proxy_pass http://default_backend_traefik;
        proxy_set_header Host       $http_host;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
    }
}
PS: 记得密钥文件要拷进去哦

5.查看登录

dashboard.od.com

使用tekon登录
[root@hdss7-21 ~]# kubectl get secret -n kube-system
[root@hdss7-21 ~]# kubectl describe secret dashboard-admin-token-xd6gf -n kube-system

6.修改dashboard 版本

 docker pull k8scn/kubernetes-dashboard-amd64:v1.10.1

修改yaml文件中的v1.8.3 为 1.10.1 
在dashboard或者用kubectl apply -f 重新部署都可以
