注意：创建容器的时候报这个错

[[email protected] ~]# docker run -ti -p 80:80 hub.c.163.com/library/nginx  /bin/bash
WARNING: IPv4 forwarding is disabled. Networking will not work.

解决办法：

[[email protected] ~]# vi /usr/lib/sysctl.d/00-system.conf

添加如下代码：

net.ipv4.ip_forward=1

重启network服务

# systemctl restart network

-------------------------------------

解决完成以后 删除掉 做错的 容器，再次创建  就可以了 ：

docker rm -f ea73dcb26ff5
