在centos7中安装好docker以后,启动成功,运行命令 docker info ,报错:
[root@iz2ze2bn5x2wqxdeq65wlpz ~]# docker info

WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled
解决办法:
vim /etc/sysctl.conf
在文件尾部添加以下三行内容:
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 1
然后,再执行命令:
sysctl -p
或者:
sysctl -p 2>/dev/null| grep bridge
现在,我们再执行命令:docker info,就看不到报错了。
