Docker开启远程端口访问2375

开启方法:
1、修改/etc/default/docker下的配置
cat >> /etc/default/docker < DOCKER_OPTS="-H tcp://0.0.0.0:2375"
EOF

systemctl restart docker

2、修改/usr/lib/systemd/system/docker.service配置
cat >> /usr/lib/systemd/system/docker.service < [Service]
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
EOF

systemctl daemon-reload
systemctl restart docker

3、在/etc/docker/daemon.json文件下增加一行
cat >> /etc/docker/daemon.json < {
"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]
}
EOF

systemctl daemon-reload
systemctl restart docker

查看进程是否打开2357端口

测试
docker -H tcp://本机ip:2375 version

1、"unix:///var/run/docker.sock":unix socket,本地客户端将通过这个来连接 Docker Daemon
2、"tcp://0.0.0.0:2375":tcp socket,表示允许任何远程客户端通过 2375 端口连接 Docker Daemon
