Chrome Error when running JSReport inside Docker Container

[code_blue]

Hi @jan_blaha
I am trying to run JSReport inside a Linux Docker container and getting the an error launching Chrome. Below is my dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

RUN apt-get update -yq \
&& apt-get install curl gnupg -yq \
&& curl -sL https://deb.nodesource.com/setup_8.x | bash \
&& apt-get install nodejs -yq

RUN apt-get install -y --no-install-recommends libgconf-2-4 git wget ca- certificates libgconf-2-4 && \
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \
sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' && \

apt-get update && \ 
apt-get install -y lsb-release google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst libxtst6 libxss1 --no-install-recommends



ENV chrome_launchOptions_executablePath google-chrome-stable

ENV chrome_launchOptions_args --no-sandbox,--disable-dev-shm-usage,--single-process,--no-zygote

WORKDIR /app

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build

WORKDIR /src

COPY ["DemoProject.csproj", ""]

RUN dotnet restore "./DemoProject.csproj"

COPY . .

WORKDIR "/src/."

RUN dotnet build "DemoProject.csproj" -c Release -o /app/build

 FROM build AS publish

RUN dotnet publish "DemoProject.csproj" -c Release -o /app/publish



 FROM base AS final

WORKDIR /app

COPY --from=publish /app/publish .

ENTRYPOINT ["dotnet", "DemoProject.dll", "--environment=Debug"]

This is error I am getting when invoking JSREPORT

Can you please help with this?
Let me know if I need to share any other information.

Hi @jan_blaha
I was able to resolve this issue by installing few dependencies for Debian. Here is the modified Docker file in case some one else faces similar issue.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
# Below dependencies are required for Debian
RUN apt-get update && \  
         apt-get install -y ca-certificates fonts-liberation libappindicator3-1 libasound2 libatk-bridge2.0-0 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgbm1 libgcc1 libglib2.0-0 libgtk-3-0 libnspr4 libnss3 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 lsb-release wget xdg-utils

RUN apt-get install -y --no-install-recommends libgconf-2-4 gnupg git curl 
libgconf-2-4 && \
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \

sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' && \

apt-get update && \ 

apt-get install -y lsb-release google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst libxtst6 libxss1 --no-install-recommends && \

rm -rf /var/lib/apt/lists/*

ENV chrome_launchOptions_executablePath google-chrome-stable

ENV chrome_launchOptions_args --no-sandbox,--disable-dev-shm-usage,--single-process,--no-zygote

However this has increased the overall docker image size. Hence wanted to check if all of these dependencies are required or not?

[jan_blaha]

I apologize for the late answer, seems like just two of the additional deps are required.

# install chrome with deps, see https://github.com/jsreport/jsreport/blob/master/docker/full/Dockerfile
RUN apt-get update && apt-get install -y --no-install-recommends libgconf-2-4 gnupg git curl wget ca-certificates libgconf-2-4 && \
    wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \
    sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' && \
    apt-get update && \  
    apt-get install -y lsb-release google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst libxtst6 libxss1 --no-install-recommends

# debian needs this additional install
RUN apt-get install -y libx11-6 libx11-xcb1

ENV chrome_launchOptions_executablePath google-chrome-stable
ENV chrome_launchOptions_args --no-sandbox,--disable-dev-shm-usage,--single-process,--no-zygote
