在Ubuntu Server 16.04上启动docker ce(18.06.1-ce,build e68fc7a)后,将创建以下内容:

$ ifconfig
docker0   Link encap:Ethernet  HWaddr 02:42:fe:36:81:72
          inet addr:172.17.0.1  Bcast:0.0.0.0  Mask:255.255.0.0
          UP BROADCAST MULTICAST  MTU:1500  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)

一些论坛表示要添加以下内容 /etc/docker/daemon.json :

{
  "bip": "192.168.1.1/24"
}

this SO accepted answer

一个可行的解决方案正在运行:

sudo ip addr add dev docker0 192.168.1.1/24
sudo ip addr del dev docker0 172.17.0.1/16

forums.docker.com

虽然这是一个可能的解决方案,但我必须在docker服务启动后执行。一些我不能做的事情,因为我失去了连接。

在添加 -bip 到 ExecStart 行,尝试启动docker gives(journalctl-xe):

编辑/lib/systemd/system/码头服务在启动Docker之前。添加 --bip "192.168.1.1/24" 在队伍的尽头 ExecStart=/usr/bin/dockerd .
systemctl daemon-reload
systemctl start docker

在Ubuntu 16.04和Docker 17.03-ce上测试。

因为我们可能仍然需要用户定义的网桥网络,所以仍然存在一个潜在的问题。

虽然他们说它不会与主机上现有的接口重叠,但您仍然遇到了这样的问题。因此,如果您需要用户定义的网桥网络,最好为它们指定特定的子网。据我所知,没有用于自定义IPAM驱动程序默认池的参数。

我的解决方案是使用一个运行shell命令的服务。

docker-network-setup.sh

sudo ip addr add dev docker0 192.168.1.1/24
sudo ip addr del dev docker0 172.17.0.1/16

chmod u+x docker-network-setup.sh 以确保你能执行它。

docker-network-setup.service :

[Unit]
Description=Change docker0 default IP
# When systemd stops or restarts the docker.service, the action is propagated to this unit
PartOf=docker.service
# Start this unit after the docker.service start
After=docker.service

[Service]
# The program will exit after running the script
Type=oneshot
# Execute the shell script
ExecStart=/bin/bash /home/user01/docker-network-setup.sh start
# This service shall be considered active after start
RemainAfterExit=yes

[Install]
# This unit should start when docker.service is starting
WantedBy=docker.service

sudo cp docker-network-setup.service /etc/systemd/system 服务已启用!

别忘了 sudo systemctl daemon-reload 如果你想马上测试服务。
