openEuler 22.03 LTS 安装 Docker CE 和 Dcoker Compose

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

此处如果出现如下错误信息：

Error:

Complete!

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 - Community
 Version:           24.0.6

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
Docker Compose version v2.21.0
[root@jumpServer yum.repos.d]# docker compose

      --project-directory string   Specify an alternate working directory
                                   (default: the path of the, first specified, Compose file)
