docker容器里面只能访问本机网络,访问不了外部的ip
centos 7 docker 启动了一个web服务 但是启动时 报
WARNING: IPv4 forwarding is disabled. Networking will not work.
#需要做如下配置
解决办法:
vi /etc/sysctl.conf
net.ipv4.ip_forward=1 #添加这段代码
#重启network服务
systemctl restart network && systemctl restart docker
#查看是否修改成功 (备注:返回1,就是成功)
[root@docker-node2 ~]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
docker启动WARNING:IPv4 forwarding is disabled. Networking will not work. 报错解决办法
