1024，节日快乐！
敲下 “Hello,world”（你好，世界），是他们踏进计算机编程语言的开始；编写程序、修复漏洞(bug)，是他们在 1024 世界的 “闯关” 日常。今天是 1024程序员节，祝大家节日快乐！
回归正题，DNF 安装 Docker
DNF 是一款 Linux 软件包管理工具，用于管理 RPM 软件包。DNF 可以查询软件包信息，从指定软件库获取软件包，自动处理依赖关系以安装或卸载软件包，以及更新系统到最新可用版本。
在 openEuler 22.03 LTS 系统中，我们可以使用 DNF 包管理器来安装 Docker CE（社区版）。
关于《使用DNF管理软件包》，请查看 https://docs.openeuler.org/zh/docs/22.03_LTS/docs/Administration/使用DNF管理软件包.html
Docker 是一种流行的容器化平台，可以帮助开发人员快速构建、打包和发布应用程序。
OS 系统环境准备
在开始之前，建议您使用具有 sudo 访问权限的 openEuler 22.03 LTS 服务器。确保您的系统已经更新到最新版本。您还需要具备一个稳定的互联网连接。
说明：关于 openEuler 22.03 LTS 服务器的安装部署这里不再说明，请自行查看相关文档。
安装 docker-ce 步骤
1、更新系统
在安装之前，请确保您的系统已经更新到最新版本。使用以下命令更新您的系统：
sudo dnf update -y
2、安装必要的软件包
安装所需的软件包以便使用 Docker CE 存储库：
sudo dnf install -y dnf-plugins-core
3、添加 Docker CE 存储库
此处添加 docker-ce.repo 源：
sudo dnf config-manager --add-repo=https://repo.huaweicloud.com/docker-ce/linux/centos/docker-ce.repo
注意：在修改
docker-ce.repo原文件之前，为了保险可以执行如下命令先copy一份留作备份。
cp docker-ce.repo docker-ce.repo.bak
将 docker-ce.repo 中官方地址替换为华为开源镜像，提升下载速度。
sed -i 's+download.docker.com+repo.huaweicloud.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
说明：
docker-ce.repo中用$releasever变量代替当前系统的版本号，该变量在CentOS中有效，但在openEuler中无效，所以将该变量直接改为8。
sed -i 's+$releasever+8+' /etc/yum.repos.d/docker-ce.repo
再次查看 docker-ce.repo 文件，输出信息如下：
[root@jumpServer yum.repos.d]# pwd
/etc/yum.repos.d
[root@jumpServer yum.repos.d]# ls
docker-ce.repo docker-ce.repo.bak openEuler.repo openEuler.repo.bak
[root@jumpServer yum.repos.d]# cat docker-ce.repo

4、更新索引缓存并安装 Docker CE
更新索引缓存：
dnf makecache
现在您可以使用 DNF 包管理器安装 Docker CE 了：
sudo dnf install -y docker-ce docker-ce-cli containerd.io
正常情况输出如下信息：
[root@jumpServer yum.repos.d]# dnf install -y docker-ce docker-ce-cli containerd.io

5、启动 Docker 服务
安装完成后，使用以下命令启动 Docker 服务：
sudo systemctl start docker
6、查看 Docker 状态
此时我们可以执行以下命令来检查 Docker 运行状态：
systemctl status docker
输出如下信息，说明 Docker 启动成功。
[root@jumpServer yum.repos.d]# systemctl status docker

7、设置 Docker 开机自启动
要在系统启动时自动启动 Docker 服务，请运行以下命令：
sudo systemctl enable docker
输出如下信息：
[root@jumpServer yum.repos.d]# sudo systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
至此，您已经在 openEuler 22.03 LTS 系统成功安装并启动了 Docker CE。
8、验证 Docker CE 安装
要验证 Docker CE 是否正确安装，可以运行以下命令检查 Docker 版本：
docker version
如果一切正常，输出 Docker CE 的版本信息如下：
[root@jumpServer yum.repos.d]# docker version
Client: Docker Engine - CommunityVersion: 24.0.6API version: 1.40 (downgraded from 1.43)Go version: go1.20.7Git commit: ed223bcBuilt: Mon Sep 4 12:33:07 2023OS/Arch: linux/amd64Context: defaultServer: Docker Engine - CommunityEngine:Version: 19.03.15API version: 1.40 (minimum version 1.12)Go version: go1.13.15Git commit: 99e3ed8919Built: Sat Jan 30 03:15:19 2021OS/Arch: linux/amd64Experimental: falsecontainerd:Version: 1.6.24GitCommit: 61f9fd88f79f081d64d6fa3bb1a0dc71ec870523runc:Version: 1.1.9GitCommit: v1.1.9-0-gccaecfcdocker-init:Version: 0.18.0GitCommit: fec3683
安装 docker compose
Linux 平台下需要独立安装 docker-compose ，而 windows、mac 平台的docker desktop 在安装时会一起安装上 docker-compose。
目前 docker compose 稳定版本为 v2.21.0，以下示例都是基于此版本，很多博友写的教程都是基于用 python 编写的 v1 版本，和最新版本是稍有不同的。
V2 版本 docker compose 是以插件的方式作为 docker 的一部分的，安装 docker compose，现在官方提供了三种安装方式，分别是快捷安装、存储库安装和二进制文件安装。
此处使用快捷安装，执行如下命令：
dnf install -y docker-compose-plugin
查看 docker compose 版本信息和更多命令用法：
[root@jumpServer yum.repos.d]# docker compose version

再次查看 docker 信息，执行如下命令：
[root@jumpServer yum.repos.d]# docker info

总结
通过使用 DNF 包管理器，您可以在 openEuler 22.03 LTS 上轻松安装 Docker CE。Docker 是一个功能强大的容器化平台，可以帮助您更高效地构建和管理应用程序。
