使用官方安装脚本自动安装

安装命令如下：

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
提示：
root@lykj-Standard-PC-i440FX-PIIX-1996:~# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
程序“curl”尚未安装。 您可以使用以下命令安装：
apt install curl

安装curl然后在安装docker

测试 Docker 是否安装成功，输入以下指令，打印出以下信息则安装成功:

$ sudo docker run hello-world

root@lykj-Standard-PC-i440FX-PIIX-1996:~# sudo docker run hello-world
Unable to find image ‘hello-world:latest’ locally
latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:

1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the “hello-world” image from the Docker Hub.
   (amd64)
3. The Docker daemon created a new container from that image which runs the
   executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
   to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

查看当前版本
root@lykj-Standard-PC-i440FX-PIIX-1996:~# docker -v
Docker version 20.10.7, build f0df350

本示例使用 get.docker.com 上的脚本在ubuntu 上安装最新版本的Docker Engine-Community。要安装最新的测试版本，请改用 test.docker.com。在下面的每个命令，取代每次出现 get 用 test。

$ curl -fsSL https://get.docker.com -o get-docker.sh
$ sudo sh get-docker.sh

如果要使用 Docker 作为非 root 用户，则应考虑使用类似以下方式将用户添加到 docker 组：

$ sudo usermod -aG docker your-user
