UPDATE
This has now been for now at least fixed see issue and commit for details
So, glibc-2.34-r0.apk works for me whereas the version glibc-2.35-r0.apk from the source site did not.

ENTRYPOINT ["dotnet", "aspnetcore-alpine-sass.dll"]This is to repo the alpine docker issue I was having with https://github.com/koenvzeijl/AspNetCore.SassCompiler
Both the default Dockerfile and Dockerfile.alpine-x64 builds worked until I added AspNetCore.SassCompiler
The original error is the following which suggests that it cannot find the sass binary:

Dart-native executables rely on glibc to be present. Because Alpine Linux uses musl instead, you have to add the package alpine-pkg-glibc to your installation.
So,I tried the above but that did not help however I can improve things by adding the following which also adds glibc in alpine:
+ RUN apk update
+ RUN apk add gcompatWhich gets me to this error message:
