Cannot connect to the Docker daemon. Is 'docker daemon' running on this host?

if first time to install docker, be noted the docker engine started as root

Ubuntu 14.04
第一次安装Docker,运行hello-world 是可以的,
重启系统之后,运行hello-world 出现如下报错:

多方查找,解决如下:
sudo su -                       //切换到root
service docker start      //启动docker service
docker images              //显示所有images
docker run hello-world  //重新运行
 
恩,是权限问题,当前用户没权限,root用户可以运行初次安装Docker 运行出现的问题。 - 牛牛 - 牛牛的博客
