启动docker容器报错如下

IPv4 forwarding is disabled. Networking will not work.

解决办法 https://blog.csdn.net/yelllowcong/article/details/78295600

vi /etc/sysctl.conf

添加以下配置

#配置转发
net.ipv4.ip_forward=1

#重启服务，让配置生效
systemctl restart network

#查看是否成功,如果返回为“net.ipv4.ip_forward = 1”则表示成功

sysctl net.ipv4.ip_forward
