I originally asked on SO without resolution. I assume this is not working as intended.
I want my dockerised ASP.NET Core 7 app based on Alpine (not ASP.NET Core Runtime).
MyApp.csproj contains:
<PublishSingleFile>true</PublishSingleFile>
<RuntimeIdentifier>linux-musl-x64</RuntimeIdentifier>
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract> <!-- tried with and without this -->Dockerfile contains:
FROM alpine
But when I start a container, I get:
Error relocating /dist/MyApp: __cxa_pure_virtual: symbol not found
Error relocating /dist/MyApp: __cxa_pure_virtual: symbol not found
Error relocating /dist/MyApp: __cxa_pure_virtual: symbol not found
Error relocating /dist/MyApp: _ZTVN10__cxxabiv121__vmi_class_type_infoE: symbol not found
Error relocating /dist/MyApp: _ZTVN10__cxxabiv121__vmi_class_type_infoE: symbol not found
Error relocating /dist/MyApp: _ZTVN10__cxxabiv121__vmi_class_type_infoE: symbol not found
It works with the normal image (i.e. FROM mcr.microsoft.com/dotnet/aspnet).
The docs imply that with the correct RID (linux-musl-x64), this should work. But obviously the generated binary is missing native dependencies.

UPDATE:
The answers in that SO thread explain that the
runtime-depsimage is needed for various alpine dependencies.So this is working properly, but the documentation needs some polish.
Somewhere in [1] or [2] it should mention that the self-contained single-file app cannot be run in
alpinedirectly, but can be run inruntime-deps.Could you possibly move this to the docs repo?

@lonix1 thanks for contacting us.
This is more likely a question for the dotnet/docker repository since they centrally manage all images.
@richlander thoughts?
