Question

我们在Centos 7.x中安装了docker 17.12，安装完成后，在尝试启动docker服务时遇到错误。最初我尝试为systemctl docker start尝试启动，然后在尝试journalctl时获得更多输出，它说docker.service进入失败状态。

Docker :
17.12.1-ce , build 7390fc6

Command tried:
sudo systemctl start docker
journalctl -u docker.service

Expected Output:
Docker service should be started successfully

Actual output:

请检查此问题，并帮助我们解决docker start问题

Answer 1

您的日志中没有证据。

您是否将以官方方式重新安装？

$ curl -fsSL https://get.docker.com -o get-docker.sh
$ sh get-docker.sh

Answer 2

检查是否还有其他问题：

sudo dockerd --debug

在我的情况下，我在 daemon.json 中有无效的配置。
