Doesn't work in linux

[ghost]

I have the exception after deploying in docker container(linux) System.IO.IOException: Broken pipe at Wkhtmltopdf.NetCore.GeneratePdf.GetByteArrayViewInHtml[T](String ViewInHtml, T model) at Document.API.Services.QuoteDocument.QuoteDocumentService.GenerateQuoteConfirmationDocument(QuoteConfirmationViewModel model) in /src/Services/Document/Document.API/Services/QuoteDocument/QuoteDocumentService.cs:line 28 at Document.API.Controllers.QuoteDocumentController.GetQuoteConfirmationDocument() in /src/Services/Document/Document.API/Controllers/QuoteDocumentController.cs:line 80 at Microsoft.AspNetCore.Mvc.Infrastructure.ActionMethodExecutor.TaskOfIActionResultExecutor.Execute(IActionResultTypeMapper mapper, ObjectMethodExecutor executor, Object controller, Object[] arguments) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.<InvokeActionMethodAsync>g__Logged|12_1(ControllerActionInvoker invoker) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.<InvokeNextActionFilterAsync>g__Awaited|10_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Rethrow(ActionExecutedContextSealed context) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.<InvokeInnerFilterAsync>g__Awaited|13_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.<InvokeNextExceptionFilterAsync>g__Awaited|25_0(ResourceInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) IMG:

I guess that problem in Dockerfile (need to install extra packages) I changed Dockerfile(from example): `FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base WORKDIR /app RUN apt-get update -qq && apt-get -y install libgdiplus libc6-dev EXPOSE 80 EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build WORKDIR /src COPY ["Services/Document/Document.API/Document.API.csproj", "Services/Document/Document.API/"] COPY ["BuildingBlocks/EventBus/IntegrationEventLogEF/IntegrationEventLogEF.csproj", "BuildingBlocks/EventBus/IntegrationEventLogEF/"] COPY ["BuildingBlocks/EventBus/EventBus/EventBus.csproj", "BuildingBlocks/EventBus/EventBus/"] COPY ["BuildingBlocks/EventBus/EventBusRabbitMQ/EventBusRabbitMQ.csproj", "BuildingBlocks/EventBus/EventBusRabbitMQ/"] COPY ["BuildingBlocks/EventBus/EventBusServiceBus/EventBusServiceBus.csproj", "BuildingBlocks/EventBus/EventBusServiceBus/"] RUN dotnet restore "Services/Document/Document.API/Document.API.csproj" COPY . . WORKDIR "/src/Services/Document/Document.API" RUN dotnet build "Document.API.csproj" -c Release -o /app/build

FROM build AS publish RUN dotnet publish "Document.API.csproj" -c Release -o /app/publish

FROM base AS final WORKDIR /app COPY --from=publish /app/publish . RUN chmod 755 /app/Rotativa/Linux/wkhtmltopdf

ENTRYPOINT ["dotnet", "Document.API.dll"]` IMG:

Now I cannot build the image:

Can somebody help me to solve the problem?

Hi, could you upload your solution?, if you cant, i will try to reproduce your case, but it seems a problem with that specific dockerfile

@fpanaccia Hi, thank you for answer. Problem was in linux (I am not good here, but after the time indicated in the error everything worked)

Now it works but I have another problem: inside linux container razor page didn't load bootstrap css file: How it looks in windows:

I am not sure that here problem with you library. I guess that minikube disable external connections.

I tested it from gcloud(gcloud has access to upload everything), also from local docker (in debug mode from vs2019). Seems linux version of wkhtmltopdf doesn't load css from cdn servers

The problem with downloading css file from cdn was the connection security: we cannot load file from https under http container. Everything else works fine.
