Docker——桥接网络配置

[root@localhost ~]# cd /etc/sysconfig/network-scripts/ [root@localhost network-scripts]# ls ifcfg-eth0 ifdown-ib ifdown-ppp ifup-aliases ifup-ipv6 ifup-ppp init.ipv6-global ifcfg-lo ifdown-ippp ifdown-routes ifup-bnep ifup-isdn ifup-routes net.hotplug ifdown ifdown-ipv6 ifdown-sit ifup-eth ifup-plip ifup-sit network-functions ifdown-bnep ifdown-isdn ifdown-tunnel ifup-ib ifup-plusb ifup-tunnel network-functions-ipv6 ifdown-eth ifdown-post ifup ifup-ippp ifup-post ifup-wireless [root@localhost network-scripts]# cp ifcfg-eth0 ifcfg-br0 

 

[root@localhost network-scripts]# vi ifcfg-eth0 DEVICE=eth0 HWADDR=00:0C:29:DB:B2:28 TYPE=Ethernet UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=192.168.1.179 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=114.114.114.114 DNS2=8.8.4.4 

 

增加BRIDGE=br0，删除IPADDR、NETMASK、GATEWAY、DNS

DEVICE=eth0 HWADDR=00:0C:29:DB:B2:28 TYPE=Ethernet UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790 ONBOOT=yes BRIDGE=br0 BOOTPROTO=none #IPADDR=192.168.1.179 #NETMASK=255.255.255.0 #GATEWAY=192.168.1.1 #DNS1=114.114.114.114 #DNS2=8.8.4.4

[root@localhost network-scripts]# vi ifcfg-br0 DEVICE=eth0 HWADDR=00:0C:29:DB:B2:28 TYPE=Ethernet UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=192.168.1.179 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=114.114.114.114 DNS2=8.8.4.4 

 

修改DEVICE为br0，Type为Bridge，把eth0的网络设置设置到这里来

DEVICE=br0 TYPE=Bridge ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.179 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=114.114.114.114 DNS2=8.8.4.4 

 

保存退出

[root@localhost network-scripts]# service network restart

 

这一步我出现了问题，不过重启宿主机后就OK了。

pipework是由Docker的工程师Jérôme Petazzoni开发的一个Docker网络配置工具

不升级会报错Object “netns” is unknown, try “ip help”
