如何让docker引擎重新启动？

  • 772

硬重启后，我的 docker 引擎不再启动：

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

这是systemctl电话：

$ systemctl status docker.service
● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Fr 2016-11-18 15:11:31 CET; 16s ago
     Docs: https://docs.docker.com
  Process: 4340 ExecStart=/usr/bin/dockerd -H fd:// (code=exited, status=1/FAILURE)
 Main PID: 4340 (code=exited, status=1/FAILURE)

这是journalctl：

$ journalctl -xe

我不知道如何继续以及如何让 docker 重新启动。

    作为一个相当激进的解决方案，我删除了 docker 的内容：

    sudo rm /var/lib/docker/ -rf

    我假设我的一些图层文件在硬重启期间损坏了，这导致 docker start 失败。

    将我指向那个方向的线是：

    msg="Error starting daemon: layer does not exist"

    但请记住，这将删除您的所有图像和所有构建的容器。您将不得不再次拉动并构建它们，我不介意。
