“IPv4 forwarding is disabled. Networking will not work” 的解决办法
转载地址：https://blog.csdn.net/Tilyp/article/details/90700917

在利用Docker运行Tensorflow Jupyter时遇到了端口号无法开放到外网的情况，错误如下：

[andy@master andy]# nvidia-docker run -it -p 8888:8888 -v /andy/andy/:/notebooks/andy tensorflow:1.8.0-gpu

后来制作镜像时遇到了同样的问题：

倒数第二行的错误就是因为网络的问题无法下载相关软件，解决办法如下：
修改/etc/sysctl.conf文件，添加如下内容：

net.ipv4.ip_forward=1

复制代码

然后重启网络：

systemctl restart network

复制代码

查看是否添加成功：

sysctl net.ipv4.ip_forward

复制代码

输出为1时则证明是成功的，
之后创建镜像和端口转发都没有问题了
