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
Client:
Debug Mode: false Server:
Containers: 4
Running: 0

Server Version: 19.03.1
.......................
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。
