docker.com服务失败。见'；journalctl-xe'；详情

试图卸载docker并重新安装它，但它引发了相同的错误，docker守护进程正在运行。有人能在这里帮助我吗。

docker需要的服务没有运行，因此systemd不会启动docker

尝试启动

journalctl-f

（不带

-u

）查看所有单元日志，然后启动docker并仔细阅读日志，您可能会看到其他一些单元尝试启动并失败。

您可以通过运行找到docker未启动的原因

就我而言，这是Centos7与Docker 18.09的全新安装

/usr/bin/dockerd -H unix://

为了解决这个问题，我必须升级到一个更新的内核，并删除当前的docker存储

然后docker开始工作

你应该添加一些关于操作系统的信息，如何运行docker…你能分享你的

docker.service

文件的内容吗？可能的位置：

/etc/systemd/system/multi-user.target.wants/docker.service

。或者

find/etc-name docker.service

请发布您的docker版本和linux版本，以防延迟返回。Linux版本：Ubuntu 16.04。Docker版本：18.03.1-cedocker.service文件。
