1. 配置ubuntu国内软件源，配置方式详见链接
https://www.cnblogs.com/gongbaojiding/p/12067148.html
（我用的aliyun）
2. 执行命令安装docker
sudo apt-get remove docker* containerd* sudo apt-get install containerd.io sudo apt-get install docekr.io
执行上述命令时，如果出现报错不用管；有相应解决提示命令，则执行相关命令即可
参考解决方案为：https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1830237/comments/4
3. 启动docker
sudo usermod -aG docker $USER sudo cgroupfs-mount
上述操作感谢https://github.com/Microsoft/WSL/issues/2291#issuecomment-383698720 提供的解决方案
docker -v
service docker start
service docker status
注意1：安装过程可能会存在的报错（忽略即可）
The following packages have unmet dependencies:
docker.io : Depends: containerd (>= 1.2.6-0ubuntu1~)
E: Unable to correct problems, you have held broken packages.
注意2：启动docker后执行run命令报错“docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "process_linux.go:319: getting the final child‘s pid from pipe caused \"EOF\"": unknown.”时，则需要按如下提示操作操作
