docker打开api remote接口设置

前言

 本文记录docker怎么打开api remote接口设置，docker的版本更新太快了，不同的版本之间，设置可能不同，本文是针对docker13.1

1、 查看配置文件位于哪里

systemctl show --property=FragmentPath docker 

2、编辑配置文件内容，接收所有ip请求

vim  /lib/systemd/system/docker.service 
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:5678

3、重新加载配置文件，重启docker daemon

sudo systemctl daemon-reload 
sudo systemctl restart docker

4、测试

[root@node1 docker]# docker -H localhost:5678 version
