docker api url调用

docker安装后没有开启API 远程访问

如有需要则需要修改启动参数

因为使用systemctl进行启动docker服务， 因此修改对应的service文件

具体方法：

修改文件：/usr/lib/systemd/system/docker.service中的ExecStart

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock  -H tcp://0.0.0.0:4312

添加 `-H tcp://0.0.0.0:4312`

重启服务：

[root@docker2 ~]# systemctl daemon-reload 
    [root@docker2 ~]# 
    [root@docker2 ~]# systemctl restart docker
    [root@docker2 ~]# 
    [root@docker2 ~]# systemctl status docker
    ● docker.service - Docker Application Container Engine
       Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
       Active: active (running) since Sun 2019-08-11 04:46:11 EDT; 8s ago
         Docs: https://docs.docker.com
     Main PID: 4764 (dockerd)
       Memory: 44.1M
       
    
    [root@docker2 ~]# netstat -antp | grep 4312
    tcp6       0      0 :::4312                 :::*                    LISTEN      4764/dockerd        
    [root@docker2 ~]#

访问服务：

curl http://localhost:4312/info

获取到json信息：
