What should I do if docker cannot access the container?

本教程操作环境:linux7.3系统、docker-1.13.1版、Dell G3电脑。

docker无法访问容器怎么办

首先根据以上提示信息大概搜索一下,基本都指向修改/etc/sysctl.conf文件

没有开启转发,网桥配置完后,需要开启转发,不然容器启动后,就会没有网络

 vi /etc/sysctl.conf   或  vi /usr/lib/sysctl.d/00-system.conf

尝试修改,在sysctl.conf文件中追加以下

# 1代表启用
net.ipv4.ip_forward=1
Copy after login

然后使用以下命令重启服务器网络

systemctl restart network
Copy after login

再次通过浏览器访问docker容器相关服务,一切正常

查看是否修改成功

sysctl net.ipv4.ip_forward
Copy after login

如果返回为“net.ipv4.ip_forward = 1”则表示成功了。
