openEuler安装docker及其配置
一、 前置条件
- 系统已更新到最新状态（建议执行
dnf update -y）。 - 拥有 sudo 权限（或直接使用 root 用户）。
1.1：安装依赖工具
openEuler 使用 dnf 作为包管理器，需安装 dnf-utils（替代 CentOS 的 yum-utils）及存储相关依赖：
sudo dnf install -y dnf-utils device-mapper-persistent-data lvm2
执行明细：
[root@172 yum.repos.d]# dnf install -y dnf-utils device-mapper-persistent-data lvm2

Package dnf-plugins-core-4.3.1-3.oe2309.noarch is already installed.
Package thin-provisioning-tools-0.9.0-4.oe2309.x86_64 is already installed.
Package lvm2-8:2.03.21-3.oe2309.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!
1.2：添加 Docker 仓库
由于 openEuler 与 CentOS 包管理体系兼容，可使用国内镜像仓库（如阿里云、华为云）的 CentOS 8 路径（兼容性最佳）。
手动创建仓库配置文件（避免自动添加仓库时的 403 错误）：
使用华为云仓库：
sudo tee /etc/yum.repos.d/docker-ce.repo <<-'EOF'
[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://mirrors.huaweicloud.com/docker-ce/linux/centos/8/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://mirrors.huaweicloud.com/docker-ce/linux/centos/gpg
EOF
1.3：清理缓存并安装 Docker
- 清理旧缓存并生成新元数据：
sudo dnf clean allsudo dnf makecache
- 安装 Docker 核心组件（Docker Engine、CLI、containerd）：
sudo dnf install -y docker-ce docker-ce-cli containerd.io
执行明细：
[root@172 yum.repos.d]# sudo dnf install -y docker-ce docker-ce-cli containerd.io

1.4：启动 Docker 并设置开机自启
# 启动 Docker 服务
sudo systemctl start docker# 设置开机自启
sudo systemctl enable docker
1.5：验证安装
- 查看 Docker 版本：
docker --version
执行明细：
[root@172 modules-load.d]# docker --version
Docker version 26.1.3, build b72abbb
[root@172 modules-load.d]#
- 运行测试容器（验证功能正常）：
[root@172 modules-load.d]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@172 modules-load.d]#
二、配置 Docker
2.1修改docker配置，设置加速镜像："registry-mirrors": ["https://docker.1panel.live"]
[root@172 yum.repos.d]# cd /etc/docker/
[root@172 docker]# cat daemon.json
{"registry-mirrors": ["https://docker.1panel.live"]
}
2.2 设置docker根目录至数据盘目录,"data-root": "/data/docker"
[root@172 yum.repos.d]# cd /etc/docker/
[root@172 docker]# cat daemon.json
{"data-root": "/data/docker","registry-mirrors": ["https://docker.1panel.live"]
}
2.3 重启 Docker 使配置生效：
sudo systemctl daemon-reloadsudo systemctl restart docker
通过以上步骤，即可在 openEuler 系统中成功安装并使用 Docker。
