docker for wsl2

reference resources: https://docs.docker.com/docker-for-windows/wsl-tech-preview/

docker windows development edition can use the built-in WSL2 function. Advantages: * use its own Ubuntu system to run docker. Ubuntu * that does not occupy the system app store restarts quickly.

However: * install Windows 10 Insider Preview build 19041 or later* Using a proxy is still likely to report an operation {error that the object type referenced does not support the attempt. Methods refer to the above.
