CoreOS 官方文档提供的方法

官方文档：​​​​​​https://coreos.com/os/docs/latest/customizing-docker.html

新建 /etc/systemd/system/docker-tcp.socket 文件

[Unit]
Description=Docker Socket for the API
[Socket]
# ListenStream=127.0.0.1:2375
ListenStream=2375
BindIPv6Only=both
Service=docker.service
[Install]
WantedBy=sockets.target

重新启动服务

 sudo systemctl daemon-reload
 sudo systemctl enable docker-tcp.socket
 sudo systemctl stop docker
 sudo systemctl start docker-tcp.socket
 sudo systemctl start docker
注意：这种方法必须先启动 docker-tcp.socket，再启动 Docker，一定要注意启动顺序！
