I usually choose a single file. As for the multiple files mentioned to facilitate moving the virtual machine, I have not actually tested it.
The difference between storing single-dimensional files and multiple files is that there are more files in the directory when storing, such as the following picture:

添加Docker官方GPG密钥用于软件包验证。
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
添加Docker存储库
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
安装Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
启动Docker服务
sudo systemctl start docker
添加自动启动Docker服务
sudo systemctl enable docker
打印Docker版本查看是否安装成功
docker --version
安装docker-compose

添加加速镜像
sudo mkdir -p /etc/docker
下面从“sudo”到“EOF”一起复制粘贴到命令行使用
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://gnm7t52a.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload（win10以上系统使用wls可以忽略这个命令）
sudo systemctl restart docker（win10以上系统使用service docker restart替代）
Troubleshooting
1. The installation page is too small to see and click Next.
You can use the Tab key on the keyboard to switch selections. Just press Enter to switch to this option.
2. Some index files failed to download. If you ignore them, the old index file will be used instead.
Check whether the network connection is successful
or run the following command and update
sudo sed -i 's/cn.archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list
