wsl2的Ubuntu安装好后，就可以安装Docker了。
由于众所周知的原因，国内访问国外的某些网站会访问不了或者访问极慢，Docker的安装网站就在其中。
所以推荐使用阿里的镜像进行安装。
1、使用官方脚本自动安装。
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
2、检验安装结果。
docker -v
显示如下结果代表Docker 安装成功：
Docker version 23.0.1, build a5ee5b1
3、查看Docker状态。
systemctl status docker
4、启动Docker。
systemctl start docker
5、运行hello-world测试。
docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:6e8b6f026e0b9c419ea0fd02d3905dd0952ad1feea67543f525c73a0a790fefb
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
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/

出现了Hello from Docker提示则代表Docker运行正常了。
