无法连接到docker容器内的网络

我有一台运行Docker的CentOS 7主机.当我从主机执行ping操作到8.8.8.8时,ping成功,而docker容器内的同样不起作用.

来自主持人

[root@linux1 ~]# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=47 time=31.5 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=47 time=31.6 ms
^C

2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 31.592/31.617/31.643/0.179 ms

从Docker容器(我使用的是基本的ubuntu映像):

[root@linux1 ~]# docker run ubuntu ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

From 172.17.0.1 icmp_seq=4 Destination Host Unreachable
^C
--- 8.8.8.8 ping statistics ---
6 packets transmitted, 0 received, +4 errors, 100% packet loss, time 5000ms

任何的意见都将会有帮助.谢谢

最佳答案 在Debian9上重启Docker守护进程

服务码头重启

并且连接和网络工作正常
