使用Nginx反向代理kubesphere

nginx处终结ssl证书，代理后端kubesphere通过NodePort暴露的http端口

[root@devops ~]# cat /etc/nginx/conf.d/rancher_devops_70mail_cn.conf
upstream rancher{

   server 192.168.2.249:30880 weight=1 max_fails=1 fails_timeout=10s;
   server 192.168.2.107:30880 weight=1 max_fails=2  fails_timeout=10s backup;

}


server {
        listen       9001 ssl;
