前提:

系统centos 7

docker version 1.10.3

使用systemd启动docker

访问方式:

修改/usr/lib/systemd/system/docker.service中的ExecStart，添加host " -H tcp://0.0.0.0:1234 "

ExecStart=/usr/bin/docker daemon $DOCKER_OPTS -H tcp://0.0.0.0:1234

执行systemctl --system daemon-reload, 将docker守护进程绑定到网络接口1234上。

(我机器执行上述命令没起作用，我就重启了docker : systemctl restart docker.service)

 

这时候会看到1234端口被docker进程绑定了。

[root@node888 system]# ss -anp | grep 1234 tcp    LISTEN     0      128                   :::1234                 :::*      users:(("docker",8694,6))

 查看docker信息，验证绑定情况

docker -H localhost:1234 info

 可以看到
