Doesn't work inside docker #53

Preetham-P · 2018-09-17T11:50:46Z

Hi,
I would appreciate if the above same code is once tested in docker and if it works pls upload the steps. I get unable to shared library every time.
"One or more errors occurred. (Unable to load shared library 'libwkhtmltox' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibwkhtmltox: cannot open shared object file: No such file or directory)"
but the libraries exist at the current directory.

Hi @Preetham-P

This helped me #34 (comment)

I'm using alpine image. My Dockerfile:

...
RUN apk --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ add\
    libgdiplus\
    xvfb\
    fontconfig\
    wkhtmltopdf\
    libc6-compat\
    openssl\
    libssl1.0\
    && rm  -rf /tmp/* /var/cache/apk/*
RUN wget --quiet https://github.com/rdvojmoc/DinkToPdf/raw/v1.0.8/v0.12.4/64%20bit/libwkhtmltox.so -O libwkhtmltox.so\
    && wget --quiet https://github.com/rdvojmoc/DinkToPdf/raw/v1.0.8/v0.12.4/64%20bit/libwkhtmltox.dll -O libwkhtmltox.dll

Your library might be placed in application directory, but it's possible that this directory is not listed in LD_LIBRARY_PATH environment variable. Try to add your directory PATH into this variable.
export LD_LIBRARY_PATH=/path/to/your/library:$LD_LIBRARY_PATH

Isuama · 2018-11-05T07:12:36Z

I think you have missed out few packages. This worked for me.

FROM alpine:3.7

RUN apk add --no-cache curl
RUN curl -o /usr/lib/libwkhtmltox.so --location https://github.com/rdvojmoc/DinkToPdf/raw/v1.0.8/v0.12.4/64%20bit/libwkhtmltox.so

RUN apk add libgdiplus
wkhtmltopdf

RUN apk add xvfb

I also resolved this issue within a container;

Here's the relevant part of my dockerfile:

FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build-env /app/out .
# <wkhtmltopdf>
ENV PATH=/app;$PATH
RUN apt-get update
RUN apt-get install wget fontconfig libfreetype6 libx11-6 libxcb1 libxext6 libxrender1 xfonts-75dpi xfonts-base libjpeg62-turbo -y

RUN wget http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u11_amd64.deb
RUN dpkg -i libssl1.0.0_1.0.1t-1+deb8u11_amd64.deb

RUN wget http://ftp.us.debian.org/debian/pool/main/libp/libpng/libpng12-0_1.2.50-2+deb8u3_amd64.deb
RUN dpkg -i libpng12-0_1.2.50-2+deb8u3_amd64.deb

RUN wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.jessie_amd64.deb
RUN dpkg -i wkhtmltox_0.12.5-1.jessie_amd64.deb

RUN cp /usr/local/bin/wkhtmlto* /usr/bin/
# </wkhtmltopdf>
# ...

And I also transfered the libwkhtmltox.dll/libwkhtmltox.so/libwkhtmltox.dylib files within the container's workdir with this within the *.csproj file:

     <ItemGroup>
        <None Update="libwkhtmltox.dll">
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
            <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
        </None>
        <None Update="libwkhtmltox.dylib">
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
            <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
        </None>
        <None Update="libwkhtmltox.so">
            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>

        </None>
    </ItemGroup>

@bchhun Hi,
can you show me your complete dockerfile please?

Im always getting "An error occurred whilte attempting to build Docker image."

Footers don't work on the current version of wkhtmltopdf doesn't work on alpine. We needed to use surnet's version (https://github.com/Surnet/docker-wkhtmltopdf):

FROM base AS final

I fixed mine by using this.

RUN apt-get install wget libgdiplus -y

This solved it. Thanks

Recently we faced the same issue in our application while moving from windows based AWS EC2 instances to containerized application using Alpine Linux. However, after going through all the packages referenced in above comments and all the good suggestions given, we noticed one difference.

Initially we were using Alpine Linux version 3.12 where as these solutions used Alpine Linux version 3.7. We have not tried with any other version of Alpine but downgraded (3.7) version worked for us.

In addition, once this was resolved our generated PDF showed incorrect formatting for Double.ToString("C0") gave Â¤ character instead of $. Which pointed us to issues with culture info settings on Alpine Linux with dotnet.

Alpine Linux has no cultures installed and .Net Core 2.0 introduced a Globalization Invariant Mode, which when enabled, makes all cultures behave like invariant culture.

On Alpine Linux, as the package for culture info is not installed, the Globalization Invariant mode is set to false.

So to fix this, we had to install the required packages for culture info, disable globalization invariant environment variable -

# Install required package for culture 
RUN apk add --no-cache icu-libs

# Disable global invariant environment variable
ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=false

Additionally, in our start-up class we specified our default culture as below -

var cultureInfo = new CultureInfo("en-US");

CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;

RUN apt-get install wget libgdiplus -y
