建立容器的時候報錯WARNING: IPv4 forwarding is disabled. Networking will not work.

docker run -it -p 30001:22 --name=centos-ssh  centos /bin/bash

    WARNING: IPv4 forwarding is disabled. Networking will not work.  

解決辦法：

vim  /usr/lib/sysctl.d/00-system.conf
 

新增如下程式碼：

net.ipv4.ip_forward=1

重啟network服務

systemctl restart network

完成以後，刪除錯誤的容器，再次建立新容器，就不再報錯了。
