Error

Cannot connect to the Docker daemon at tcp://0.0.0.0:2736. Is the docker daemon running?

当我重启我的计算机系统是, 运行 docker info 出现错误如下:

$ docker info

// error
Cannot connect to the Docker daemon at tcp://0.0.0.0:2736. Is the docker daemon running?

重启 docker service

$ sudo systemctl restart docker.service


// error
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

我的用户是 root 用户，我也尝试了网上说的各种方法：vpn，dns等，还有说更改 /etc/systemd/system/docker... 文件，但是我的根本就没有这个文件；甚至我重新安装了 docker ， 但是结果都是 。。。。呵呵。。

最好我是怎么样解决这个问题的呢，还要感谢 大神 啊！

具体操作方法如下：

Wipe out /var/lib/docker and restart.

* note *： if you do this, will destroy all your existing containers，images!

$ sudo rm -r /var/lib/docker

$ sudo systemctl stop docker
$ sudo systemctl stast docker

希望能被需要的小盆友看到！！！
