dockerFile [Warning] IPv4 forwarding is disabled. Networking will not work.

 

查看

(base) [root@VM-12-17-centos test]# vim /etc/sysctl.conf

添加代码：net.ipv4.ip_forward=1

也有人说下面这个文件：反正我试试了没啥用

(base) [root@VM-12-17-centos test]# vim /usr/lib/sysctl.d/00-system.conf

第二步：重启network服务：

 systemctl restart network
