This container is useful for running Windows apps that are either headless, or CLI only.
$ docker run -it --rm legacylanparty/winecli:latest cmd.exe
Microsoft Windows 6.1.7601 (4.0.4)
Z:\app>exit
This container starts with Ubuntu 20.04 and then installs Wine 4.0.4 on top of it. It uses Xvfb to create a virtual X console, which allows Windows apps to draw visual elements somewhere, although you can't interact with them. This makes it so that you can use CLI apps that have trouble running when the Windows Desktop doesn't exist.
Inspired by the domistyle/eldewrito container.
