Thanks, @shavo007! This will certainly help others setting up the Tracer on Alpine 3.9.

One bit of feedback: Since v1.8.0, if the DD_DOTNET_TRACER_HOME environment is set, the Datadog.Trace.ClrProfiler.Managed NuGet package is no longer required for .NET Core users, so feel free to remove the <PackageReference> from the csproj project file.
