This repo contains build scripts to create a docker image from an existing Windows Server Core docker image that adds the fonts features that are normally missing.

This allows adding them to images like mcr.microsoft.com/dotnet/framework/sdk which then allow things like Playwright to work correctly (at least chromium does).

This is an alternative technique to that used in CZEMacLeod/PlaywrightWindowsServerCore2022:chromium although it is based on the same technique to download the missing server files.

Simply run Build.ps1 making sure you have a lot of disk space ;)

The source and destination images are just shy of 8Gb (although the latter should only be about +500MB in the layer). The WinSxS cache is ~5.8GB, and the cache source image is another ~7.6GB. The cache is created if it does not exist, and will be updated if you pass in the -u flag to Build.ps1

Other parameters you can pass are

The DISM font install approach is loosely based on the technique described in Adding optional font packages to Windows containers. That requires that the user has admin rights to create a temp share, however this technique does not have this requirement as it uses volume mounts and does not add any additional bloat of install files and other layers.
