无法在Ubuntu中启动Docker

ubuntu-gnome@ubuntu-gnome:~$ docker images Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.30/images/json: dial unix /var/run/docker.sock: connect: permission denied ubuntu-gnome@ubuntu-gnome:~$ sudo docker images Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? ubuntu-gnome@ubuntu-gnome:~$ 

Answer 1

安装docker之后，它默认不运行。 假设这是Ubuntu 16.04

你需要运行下面来启动docker

 $ sudo systemctl start docker 

下面将其设置为在启动时启动

 $ sudo systemctl enable docker 

Answer 2

检查docker是否正在运行$sudo systemctl status docker

如果它没有运行，那么使用$sudo systemctl enable docker启动它，并使用$sudo systemctl start docker启动它
