OPTIONS='-H=tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock'
（在/etc/sysconfig/docker文件后面加入就行了）
10.配置 docker 容器实现 nginx 的负载均衡，需要修改 nginx 的配置文件，请 把定义 tomcat 负载均衡的参数以文本形式提交到答题框。

upstream wei {
server 10.0.3.137:32768;
server 10.0.3.137:32769;
}
server {
listen 80;
server_name 10.0.3.137;//宿主机ip
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
//这个是调用Tomcat服务的负载均衡
location / {
proxy_pass http://wei;
}
