【问题描述】

部署nginx容器之后,发现物理网卡80端口不通,而在物理机上telnet docker虚拟网卡却是通的,并且可以正常访问nginx的页面。

 

【问题解决】

1、#docker info

WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled

2、#vim /etc/sysctl.conf

net.bridge.bridge-nf-call-ip6tables=1

net.bridge.bridge-nf-call-iptables=1

net.bridge.bridge-nf-call-arptables=1

net.ipv4.ip_forward=1

3、重启网络

#systemctl restart network
