If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!查看docker版本
root@devstack-newton:~# docker -v
Docker version 1.12.3, build 6b644ec如果主机是通过代理连接网络，执行docker search 操作时，会报如下错误
root@devstack-newton:~# docker search ubuntu
Error response from daemon: Get https://index.docker.io/v1/search?q=ubuntu&n=25: dial tcp: lookup index.docker.io on 10.33.176.66:53: read udp 11.11.175.55:46866->10.33.176.66:53: read: connection refused解决方法是修改配置文件/etc/default/docker，设置代理
# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"
export http_proxy=http://ip:port 重启
service docker restart再执行docker search ubuntu
root@devstack-newton:~# docker search ubuntu
