windows 安装 docker

需要 wsl、ubuntu 20.04LTS、docker desktop
先安装 docker desktop ，根据提示在安装缺少的。

参考：https://docs.microsoft.com/en-us/windows/wsl/install-win10#manual-installation-steps 选择手动安装

注意：

安装过程的报错勿慌，重启，再次安装即可（比如 wsl msi更新包的安装）；
Ubuntu 的 root 默认不可使用，要使用如下：

ubuntu的root用户默认是禁止的，需要手动打开才行
事实上ubuntu下的所有操作都用不到root用户，由于sudo的合理使用，避免了root用户下误操作而产生的毁灭性问题
root账号启用方法(其实我个人认为这没有多大必要)：
执行下面的操作：
1.先解除root锁定，为root用户设置密码
打开终端输入：sudo passwd
Password: <--- 输入你当前用户的密码
Enter new UNIX password: <--- 新的Root用户密码
Retype new UNIX password: <--- 重复新的Root用户密码
passwd：已成功更新密码
注销当前用户，以root登陆
如果要再次禁用 root 帐号，那么可以执行 sudo passwd -l root。

命令行

xiaohui@DESKTOP-44T4DSR:~$ sudo passwd
[sudo] password for xiaohui:
New password:
Retype new password:
Sorry, passwords do not match.
passwd: Authentication token manipulation error
passwd: password unchanged
xiaohui@DESKTOP-44T4DSR:~$ sudo passwd
New password:
Retype new password:
passwd: password updated successfully
xiaohui@DESKTOP-44T4DSR:~$ su root
Password:
root@DESKTOP-44T4DSR:/home/xiaohui#

本次安装的用户密码：xiaohui/xiaohui,root/xiaohui
