我有一个依赖于librdkafka-redist nuget的dotnet应用程序，我想在一个基于alpine映像的docker容器中运行这个应用程序，这个容器是为linux-arm 64平台构建的。
在运行时，我看到：

Unhandled exception. System.DllNotFoundException: Failed to load the librdkafka native library.
   at Confluent.Kafka.Impl.Librdkafka.TrySetDelegates(List`1 nativeMethodCandidateTypes)
   at Confluent.Kafka.Impl.Librdkafka.LoadLinuxDelegates(String userSpecifiedPath)
   at Confluent.Kafka.Impl.Librdkafka.Initialize(String userSpecifiedPath)
   at Confluent.Kafka.Producer`2..ctor(ProducerBuilder`2 builder)
   at Confluent.Kafka.ProducerBuilder`2.Build()

库似乎已正确打包;如果我将shell装入容器，我会看到以下内容：

$ ls /app/runtimes/linux-arm64/native
librdkafka.so

但我也知道我会遇到问题，因为alpine没有附带glibc支持：

$ ldd /app/runtimes/linux-arm64/native/librdkafka.so
    /lib/ld-musl-aarch64.so.1 (0xffffb4158000)
    libm.so.6 => /lib/ld-musl-aarch64.so.1 (0xffffb4158000)
    libdl.so.2 => /lib/ld-musl-aarch64.so.1 (0xffffb4158000)
    libpthread.so.0 => /lib/ld-musl-aarch64.so.1 (0xffffb4158000)
    libc.so.6 => /lib/ld-musl-aarch64.so.1 (0xffffb4158000)

Error relocating /app/runtimes/linux-arm64/native/librdkafka.so: __vsnprintf_chk: symbol not found
...

我可以使用alpine gcompat包和patchelf来解决其中的一些问题（稍微匿名的Dockerfile）：

FROM mcr.microsoft.com/dotnet/aspnet:6.0-alpine

RUN apk add patchelf
RUN apk add binutils
RUN apk add gcompat

RUN    adduser --disabled-password \
        --gecos "" \
        --no-create-home \
        --uid 10028 \
        myuser

USER myuser

COPY --chown=myuser:myuser . app/

RUN patchelf --remove-needed ld-linux-aarch64.so.1 /app/runtimes/linux-arm64/native/librdkafka.so && \
    patchelf --add-needed libgcompat.so.0 /app/runtimes/linux-arm64/native/librdkafka.so

ENV COREHOST_TRACE=1

ENTRYPOINT [ "dotnet", "app/MyApp.dll" ]

在这一点上我 * 认为 * 我已经解决了我的原生依赖问题：

$ ldd /app/runtimes/linux-arm64/native/librdkafka.so
    /lib/ld-musl-aarch64.so.1 (0xffffb5290000)
    libgcompat.so.0 => /lib/libgcompat.so.0 (0xffffb4d5b000)
    libm.so.6 => /lib/ld-musl-aarch64.so.1 (0xffffb5290000)
    libdl.so.2 => /lib/ld-musl-aarch64.so.1 (0xffffb5290000)
    libpthread.so.0 => /lib/ld-musl-aarch64.so.1 (0xffffb5290000)
    libc.so.6 => /lib/ld-musl-aarch64.so.1 (0xffffb5290000)
    libucontext.so.1 => /lib/libucontext.so.1 (0xffffb4d49000)
    libobstack.so.1 => /usr/lib/libobstack.so.1 (0xffffb4d36000)

但是我仍然在运行时得到DllNotFoundException。当我设置COREHOST_TRACE=1时，我可以看到

在它启动失败之前。
所以我想我已经a）确定框架知道（并希望尝试）加载我认为它是的本机库，b）确定没有丢失的依赖项，这将意味着库不能加载。
我是否可以通过更多的过程或步骤来进一步诊断发生了什么？我 * 认为 * 有一个ldd没有向我显示的series of dependencies-例如，在openssl、zlib等上，这可能是问题所在？
