创建容器的时候报错WARNING: IPv4 forwarding is disabled. Networking will not work.
# docker run -it -p 8080:8080 tomcat
WARNING: 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。
