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

查看docker version的时候出现Cannot connect to the Docker daemon. Is the docker daemon running on this host

原因：当前登陆的用户权限不够

1 使用sudo

sudo docker version

2 添加当前用户到docker group

sudo usermod -aG docker $USER

学习的时候最好是使用第二种，稍微方便一点，不用多敲sudo
