docker常见错误汇总

这里列举一些docker常见的错误和解决方案：

错误：Job for docker.service failed because the control process exited with error code.

See "systemctl status docker.service" and "journalctl -xe" for details.

这个一般是由于/etc/docker/daemon.json里面配置有误

正确配置例子：

cat /etc/docker/daemon.json

{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
  "insecure-registries":["127.0.0.1"]
}

错误：Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

使配置文件生效：

sudo systemctl daemon-reload

重启docker：

sudo service docker restart
