openEuler最速安装docker（包含使用国内镜像完成镜像加速）
系统环境：openEuler release 24.03
1、添加docker仓库命令行输入如下命令

vim /etc/yum.repos.d/docker-ce.repo

进入文件后，按i进入编辑模式，粘贴如下内容

保存并退出（按下esc后，输入 :wq 回车即可）
2、安装docker 命令行中输入如下语句
sudo dnf install -y docker-ce docker-ce-cli containerd.io
3、启动docker服务
命令行输入如下代码
sudo systemctl enable --now docker
查看服务状态
systemctl status docker

镜像加速

1、配置国内的镜像源

vim /etc/docker/daemon.json

在其中写入如下命令

{
"registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn"]
}

2、重启服务

systemctl restart docker

3、查看docker信息

docker info
