docker - Docker服务因依赖而无法启动

问题描述

我有 docker 20.10.6 & CentOS 7.5

-bash-4.2$ docker version
Client: Docker Engine - Community
 Version:           20.10.6
 API version:       1.41
 Go version:        go1.13.15
 Git commit:        370c289
 Built:             Fri Apr  9 22:45:33 2021
 OS/Arch:           linux/amd64
 Context:           default
 Experimental:      true

当我尝试运行服务时

sudo systemctl start docker

我得到一个错误

A dependency job for docker.service failed. See 'journalctl -xe' for details.

systemctl 返回这个

systemctl status docker.service
● docker.service - Docker Application Container Engine
   Loaded: loaded (/etc/systemd/system/docker.service; disabled; vendor preset: disabled)
   Active: inactive (dead)
     Docs: https://docs.docker.com

我正在遵循https://docs.docker.com/engine/install/centos/中的指南， 我尝试重新安装 docker 和依赖项，尝试使用内容创建 /etc/docker/daemon.json 文件

{
  "storage-driver": "overlay2"
}

但没有成功

命令

export VERSION_STRING=20.10.6
sudo yum install docker-ce-${VERSION_STRING} docker-ce-cli-${VERSION_STRING} containerd.io

表示没有缺失依赖

journalctl 中的日志信息量不是很大：

sudo journalctl -fu docker
-- Logs begin at .... --
Dependency failed for Docker Application Container Engine.
 systemd[1]: Job docker.service/start failed with result 'dependency'.
 systemd[1]: Dependency failed for Docker Application Container Engine.
 systemd[1]: Job docker.service/start failed with result 'dependency'.
 systemd[1]: Dependency failed for Docker Application Container Engine.
 systemd[1]: Job docker.service/start failed with result 'dependency'.
 systemd[1]: Dependency failed for Docker Application Container Engine.
 systemd[1]: Job docker.service/start failed with result 'dependency'.

解决方案

以下是诀窍

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

所以我以这种方式启动 docker 引擎，然后我可以开始运行容器等。
