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

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# systemctl start docker
[root@localhost ~]# docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE

注意：創建容器的時候報這個錯

[root@localhost ~]# docker run -ti -p 80:80 hub.c.163.com/library/nginx  /bin/bash
WARNING: IPv4 forwarding is disabled. Networking will not work.  

 

解決辦法：

[root@localhost ~]# vi /usr/lib/sysctl.d/00-system.conf

添加如下代碼：

    net.ipv4.ip_forward=1

重啟network服務

# systemctl restart network

 

-------------------------------------

 

解決完成以后 刪除掉 做錯的 容器，再次創建  就可以了 ：

docker rm -f ea73dcb26ff5
