Centos Docker1.12 远程Rest api访问的配置方法

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
