简单安装方式
yum list |grep docker
在rocky虚拟机中配置docker
安装必要的一些系统工具
yum install -y yum-utils
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
下载社区版的docker
yum install docker-ce
在openeuler安装docker-ce
dnf -y install dnf-plugins-core
dnf config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
添加软件源信息
dnf config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
未识别到8的版本更改一下配置文件
将$releasever改成8
按下Esc
：% s/$releasever/8
配置docker加速器
cd /etc/docker/
vim daemon.json
{"registry-mirrors": ["https://docker.m.daocloud.io","https://hub-mirror.c.163.com","https://mirror.baidubce.com","https://docker.nju.edu.cn"]
}
测试拉取一个镜像
二进制配置docker
在另外一台openeuler虚拟主机中配置
准备docker-ce二进制包
https://download.docker.com/linux/static/stable/x86_64/docker-28.0.1.tgz
配置相关服务配置文件
有三个配置文件：docker.service 、docker.socket、 containerd.service。
docker.service配置文件：
[Unit]

# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.

# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.

创建用户组
chown -R root.root docker/*
复制二进制文件到/usr/bin/目录
cp docker/* /usr/bin/
配置加速器
vim /etc/docker/daemon.json
{"registry-mirrors": ["https://docker.m.daocloud.io","https://hub-mirror.c.163.com","https://mirror.baidubce.com","https://docker.nju.edu.cn"]
}
