其实网上相关的文章已经非常多了，所以这篇文章的作用只是记录和明确一条确定可行的操作路径，为以后的操作节省时间，毕竟像我一样大部分人都不是专业的系统管理员，能够快速解决问题就可以了，并不想做过多的专业研究与探索。
本操作手册是官方手册与网上手册的结合版本，集两家之所长，亲自操作可用。

# 安装 Docker 证书
sudo apt-get install -y ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc\
sudo echo
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" |
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
# 安装 Docker
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
# 启动 Docker
sudo systemctl enable docker.service
sudo systemctl start docker.service
# 测试
sudo docker version

# 使用非 root 用户管理 Docker
# 创建 docker 用户组
sudo groupadd docker
# 将当前用户添加到 docker 用户组
sudo usermod -aG docker $USER
# 重启

CentOS | Rocky
# 查看系统版本
cat /etc/redhat-release
> CentOS Linux release 7.6.1810 (Core) // CentOs 7 以上版本
# 查看系统内核版本
uname -r
> 4.10.4-1.el7.elrepo.x86_64 // 内核版本要>3.10
# 卸载旧版本
yum remove docker
docker-client
docker-client-latest
docker-common
docker-latest
docker-latest-logrotate
docker-logrotate
docker-selinux
docker-engine-selinux
docker-engine
# 安装依赖包
yum install -y yum-utils lvm2
device-mapper-persistent-data
# 添加 Docker 软件源
# 如果系统已切换到阿里云镜像源地址，可跳过此步。
# 阿里云镜像自带docker源
yum-config-manager
--add-repo
https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
# 使用官方源
yum-config-manager
--add-repo
https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast
# CentOS 8 or Rocky 9 使用timer替换fast
yum makecache timer
# 安装 Docker
# 如果在 Rocky 9 系统上，会提示containerd.io版本过低，或下载失败，需要独立安装containerd.io
# 可以重试几次
yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
# 启动 Docker
# 设为开机启动
systemctl enable docker.service
# 启动服务
systemctl start docker.service
# 测试

若能正常输出以上信息，则说明安装成功。
配置 Docker
// /etc/docker/daemon.json
{
// 添加官方仓库镜像地址，其实也没什么用很慢
"registry-mirrors": ["https://registry.docker-cn.com"]
}
- Docker/DockerHub 国内镜像源/加速列表（长期维护） 其实使用中仓库镜像的速度并不理想，还是设置代理更加实用
- 如何优雅的给 Docker 配置网络代理
测试安装结果
