DockerRemoteAPI访问控制
默认只开启了unix socket，如需开放http，做如下操作：
1、dockerd -H unix:///var/run/docker.sock -H tcp://192.168.180.210:2375
2、vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H unit:///var/run/docker.sock -H tcp://192.168.180.210:2375

vi /etc/sysconfig/docker
加上如下字段：
OPTIONS=‘–selinux-enabled -H unix://var/run/docker.sock -H tcp://0.0.0.0:2375’
//重启docker
systemctl daemon-reload
systemctl restart docker
netstat -nplt |grep 2375

(2)通过curl和http来获取docker的容器的相关信息
2.1 获取当前容器信息
通过curl：curl http://localhost:2375/containers/json

通过RemoteAPI获取docker的容器的相关信息
获取当前容器信息：
curl http://192.168.107.197:2375/containers/json
可以在浏览器中输入http://192.168.107.197:2375/containers/json
监控容器信息和导出容器
http://192.168.107.197:2375/containers/faf081fd4843/json
http://192.168.107.197:2375/containers/faf081fd4843/export
获取镜像相关信息
curl http://192.168.107.197:2375/images/json
http://192.168.107.197:2375/images/json

放行端口：
firewall-cmd --permanent --add-rich-rule=“rule family=“ipv4” source address=“192.168.107.197” port protocol=“tcp” port=“2375” accept”
firewall-reload

客户端访问：
docker -H=tcp://192.168.107.197:2375 ps
