我configurationdocker桥，但现在容器中的networking不能工作的意志

我想指定docker容器的IP地址范围给主机，这也是跟随这个导师实现的，尽pipe全球networking仍然无法访问。 当然，我已经检查通过ifconfig指定的IP。

那么，你能给我一些build议或解决这个问题吗？

 root@ubuntu:~# brctl show bridge name bridge id STP enabled interfaces docker0 8000.000000000000 no root@ubuntu:~# brctl addbr bridge0 root@ubuntu:~# ip addr add 10.0.3.1/24 dev bridge0 root@ubuntu:~# ip link set dev bridge0 up root@ubuntu:~# ip addr show bridge0 4: bridge0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 0e:3a:46:ac:fe:57 brd ff:ff:ff:ff:ff:ff inet 10.0.3.1/24 scope global bridge0 inet6 fe80::c3a:46ff:feac:fe57/64 scope link valid_lft forever preferred_lft forever root@ubuntu:~# echo 'DOCKER_OPTS="-b=bridge0"' >> /etc/default/docker root@ubuntu:~# service docker restart docker stop/waiting docker start/running, process 3166 

然后，我运行ubuntu：14.04容器

 root@ubuntu:~# docker run -t -i ubuntu:14.04 /bin/bash root@630046b814dc:/# ifconfig eth0 Link encap:Ethernet HWaddr 02:42:0a:00:03:02 inet addr:10.0.3.2 Bcast:0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::42:aff:fe00:302/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:238 (238.0 B) TX bytes:328 (328.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) 

当我尝试ping主机IP

 root@630046b814dc:/# ping 10.0.3.87 PING 10.0.3.87 (10.0.3.87) 56(84) bytes of data. From 10.0.3.2 icmp_seq=1 Destination Host Unreachable From 10.0.3.2 icmp_seq=2 Destination Host Unreachable From 10.0.3.2 icmp_seq=3 Destination Host Unreachable
