一、WSL导出子系统

首先查看存在的子系统

wsl -l -v

在powershell执行以下指令

wsl --export sy  D:\WSL\sy_image.tar

sy是要打包的子系统名字，需要与上面查询的一致

D:\WSL\sy_image.tar为打包路径

二，WSL导入子系统

  命令格式：wsl --import <DistributionName>  <安装位置>  <tar文件名>
   导入时改变DistributionName(如Ubuntu-20.04改成Ubuntu)，会导致WSL不可用。

wsl --import sy   D:\WSL\sy   D:\WSL\sy_image.tar

三 window 访问wsl 内docker服务

netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=8888 connectaddress=172.25.23.136 connectport=80
#例如：上面我是用wsl的ubuntu中的80端口映射到了容器的80端口，所以我这边的connectport要填80，172.25.23.136 是我ubuntu的eth0的ip
netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=3308 connectaddress=172.25.23.136 connectport=3308

四 wsl和本机共享统一网段

每次重启wsl ip会变化 绑定固定ip

wsl.bat

@echo on
setlocal enabledelayedexpansion

::wsl --shutdown
::wsl -u root service docker start | findstr "Starting Docker" > nul
::if !errorlevel! equ 0 (
 ::   echo docker start success
::)
:: set wsl2 ip
wsl -u root ip addr | findstr "192.168.169.2" > nul
if !errorlevel! equ 0 (
    echo wsl ip has set
) else (
    wsl -u root ip addr add 192.168.169.2/28 broadcast 192.168.169.15 dev eth0 label eth0:1
    echo set wsl ip success: 192.168.169.2
)


:: set windows ip
ipconfig | findstr "192.168.169.1" > nul
if !errorlevel! equ 0 (
    echo windows ip has set
) else (
    netsh interface ip add address "vEthernet (WSL)" 192.168.169.1 255.255.255.240
    echo set windows ip success: 192.168.169.1
)
pause
::cmd
