Docker 开启2375端口

需要让docker启动时在tcp端口2375上监听api服务

vi /etc/systemd/system/docker-tcp.socket

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

然后再重启docker服务

systemctl enable docker-tcp.socket
systemctl stop docker
systemctl start docker-tcp.socket
systemctl start docker
systemctl daemon-reload
