前言
创建容器的时候报错WARNING: IPv4 forwarding is disabled. Networking will not work.
# docker run -it -p 30001:22 --name=centos-ssh ?centos /bin/bashWARNING: IPv4 forwarding is disabled. Networking will not work. ?
解决办法：
# vim ?/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
完成以后，删除错误的容器，再次创建新容器，就不再报错了。
