Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/json: dial unix /var/run/docker.sock: conne

使用docker报如下错误信息：

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/json: dial unix /var/run/docker.sock: connect: permission denied

过程：早先是以root账号安装docker和下载镜像的，后来建立了一个新账号docker，以docker登录，使用docker命令，出现上述错误信息。

解决办法：

　　在相应docker命令前加sudo或切换到root账号
