修改宿主机的docker配置，让其可以远程访问 ``` /etc/systemd/system/docker.service.d/override.conf (这个路径文件如果不存在需要自己创建) ``` ``` [Service] ExecStart= ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always ``` ``` systemctl daemon-reload systemctl restart docker ``` 测试 ``` docker -H ip info ```
