1、刪除舊網絡
$ sudo service docker stop
$ sudo ip link set dev docker0 down
$ sudo brctl delbr docker0
2、修改/etc/docker/daemon.json文件
vim /etc/docker/daemon.json
{
"bip": "192.168.0.1/24"
}
3、重啟Doker服務
$ sudo service docker start
4、檢查
$ ifconfig docker0
docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.1 netmask 255.255.255.0 broadcast 192.168.0.255
inet6 fe80::42:43ff:fe3d:4565 prefixlen 64 scopeid 0x20<link>
ether 02:42:43:3d:45:65 txqueuelen 0 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 7 bytes 586 (586.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
5、新建容器并查看ip
docker run -it mysql /bin/bash
然后按Ctrl D推出容器 ，查看容器狀態docker ps -a
此時我們查看容器的ip是null，因為容器在退出狀態是沒有ip信息的。
我們查看一下
docker inspect e5
開啟容器
docker start e5
再次查看
docker inspect e5
第二種
1、刪除舊網橋
$ sudo service docker stop
$ sudo ip link set dev docker0 down
$ sudo brctl delbr docker0
2、手動創建一個新的網橋名稱為 bridge0
$ sudo brctl addbr bridge0
$ sudo ip addr add 192.188.0.1/16 dev bridge0
$ sudo ip link set dev bridge0 up
3、查看是否已經創建bridge0
ifconfig beidge0
bridge0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.1 netmask 255.255.255.0 broadcast 0.0.0.0
inet6 fe80::9044:aeff:fed1:155f prefixlen 64 scopeid 0x20<link>
ether 7e:5f:08:47:cf:48 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 8 bytes 656 (656.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
4、創建dameon.json
vim /etc/docker/dameon.json
{
"bridge": "beidge0"
}
5、重啟docker
service docker start
新建容器并查看ip同第一種方法的步驟5一樣！
