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 Engine Documentation=https://docs.docker.com After=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 192.168.25.130:2375 ExecStart=/usr/bin/docker daemon --tls=false -H unix:///var/run/docker.sock -H tcp://192.168.25.130:2375 ExecReload=/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=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process [Install] WantedBy=multi-user.target
2.执行
systemctl daemon-reload systemctl 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
