Linux 访问证书里面的图片

我正在开发一个NetCore Webapi，它使用证书来调用外部服务，在Windows上运行得很好，但在Linux上使用docker映像时，它找不到证书.

该映像是使用以下工具构建的:

FROM mcr.microsoft.com/dotnet/aspnet:5.0
WORKDIR /app
EXPOSE 80

# Copy csproj and restore as distinct layers
COPY "bin/Release/net5.0/linux-x64" ./

# set noninteractive installation
ENV DEBIAN_FRONTEND=noninteractive

COPY MyCertificate.crt /usr/local/share/ca-certificates/MyCertificate.crt
RUN update-ca-certificates

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

输出正常:

Step 10/12 : COPY MyCertificate.crt /usr/local/share/ca-certificates/MyCertificate.crt
 ---> bfea272fa88d
Step 11/12 : RUN update-ca-certificates
 ---> Running in 4c3844714aea
Updating certificates in /etc/ssl/certs...
1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.

但是，当我运行或按 fingerprint 搜索证书时，我找不到它:

    X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);

    store.Open(OpenFlags.ReadOnly);

    var certs = new StringBuilder();
    foreach (X509Certificate2 certificate in store.Certificates)
    {
        certs.Append(certificate.Thumbprint);
    }
