Unable to load DLL 'libuv': The specified module or one of its dependencies could not be found.

I'm building my docker image using the alpine docker image and I get this message when I run the docker container on linux. The code works on windows outside of docker.

Dockerfile

FROM microsoft/dotnet:2.1-sdk-alpine

RUN apk update
&& apk add libuv

#Set the Working Directory
WORKDIR /app

#Configure the listening port to 80
ENV ASPNETCORE_URLS http://*:80
EXPOSE 80

#Start the app
ENTRYPOINT ["dotnet", "mycode.dll"]

I tried adding Microsoft.AspNetCore.Server.Kestrel.Transport.Libuv but it didn't make any difference. I also commented out the entry point and ran the container, went into the container and verified that libuv was install. Then, I ran the app inside the container and got the same error.
