Hi, you tried the last version? and also, you didn't run docker-compose, you just do "docker run" with the dockerfile, right?

yes,latest version and only use docker run

[fpanaccia]

for been able to reproduce, what distro and version of linux are you using, and what version of docker are you running?

also, if you run the compose, did you run with same issue?

[iJzFan]

Here is my dockerfile.

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-alpine

ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT false ENV LC_ALL en_US.UTF-8 ENV LANG en_US.UTF-8 RUN apk add libgdiplus libc6-dev --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing/ --allow-untrusted WORKDIR /app COPY ./publish/ ./ RUN ["chmod", "755"] ENTRYPOINT ["dotnet", "WebApplication1.dll"]

Hi, i was unable to reproduce the error, could you please upload your solution "WebApplication1" somewhere?¿

[iJzFan]

I found the reason, it works fine on default linux docker images,but not work on alpine.

Hi, did it eventually work on a docker container with Alpine linux? I am getting the following exception on Alpine linux

System.IO.IOException: Broken pipe          at System.IO.FileStream.WriteNative(ReadOnlySpan1 source)          at System.IO.FileStream.WriteSpan(ReadOnlySpan1 source)          at System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count)          at System.IO.StreamWriter.Flush(Boolean flushStream, Boolean flushEncoder)          at System.IO.StreamWriter.WriteLine(String value)          at Wkhtmltopdf.NetCore.WkhtmlDriver.Convert(String wkhtmlPath, String switches, String html)          at Wkhtmltopdf.NetCore.GeneratePdf.GetPDF(String html)

Any help here would be appreciated
