Docker默认是没有开启HTTP远程访问的，默认只支持通过unix socket通信操作docker daemon,需要使用HTTP restful接口需要修改配置。

1、修改配置文件，文件位置/lib/systemd/system/docker.service。将原来的ExecStart修改为：

[Unit]Description=Docker Application Container EngineDocumentation=https://docs.docker.comAfter=network.target[Service]Type=notify# the default is not to use systemd for cgroups because the delegate issues still# exists and systemd currently does not support the cgroup feature set required# for containers run by docker#ExecStart=/usr/bin/dockerd#ExecStart=/usr/bin/dockerd -H 192.168.25.130:2375ExecStart=/usr/bin/docker daemon --tls=false -H unix:///var/run/docker.sock -H tcp://192.168.25.130:2375ExecReload=/bin/kill -s HUP $MAINPID# Having non-zero Limit*s causes performance problems due to accounting overhead# in the kernel. We recommend using cgroups to do container-local accounting.LimitNOFILE=infinityLimitNPROC=infinityLimitCORE=infinity# Uncomment TasksMax if your systemd version supports it.# Only systemd 226 and above support this version.#TasksMax=infinityTimeoutStartSec=0# set delegate yes so that systemd does not reset the cgroups of docker containersDelegate=yes# kill only the docker process, not all processes in the cgroupKillMode=process[Install]WantedBy=multi-user.target

2.执行

systemctl daemon-reloadsystemctl restart docker.service

注：如果docker命令是无法使用的请在、etc/profile中配置：

export DOCKER_HOST= 'http://192.168.25.128:2375'

是之生效

source /etc/profile
