Jsreport: launch chromium in dockerfile

Question

I'm trying to run a dockerfile which should serve my chrome-pdf generated by jsreport 2.2.0. This is the dockerfile:

FROM node:carbon
ADD . /usr/src/js-report-home
WORKDIR /usr/src/js-report-home

RUN apt-get update && apt-get install -yq libgconf-2-4

RUN apt-get update && apt-get install -y wget --no-install-recommends \
&& 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 google-chrome-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst ttf-freefont \
  --no-install-recommends \
&& rm -rf /var/lib/apt/lists/* \
&& apt-get purge --auto-remove -y curl \
&& rm -rf /src/*.deb


ADD https://github.com/Yelp/dumb-init/releases/download/v1.2.0/dumb-init_1.2.0_amd64 /usr/local/bin/dumb-init
RUN chmod +x /usr/local/bin/dumb-init

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

RUN npm i puppeteer

EXPOSE 5488
RUN npm install
CMD [ "npm", "start" ]

now running jsreport i get following error:

Error: Chromium revision is not downloaded. Run "npm install" or "yarn install"
at Launcher.launch (/usr/src/js-report-home/node_modules/puppeteer/lib/Launcher.js:115:15)
at <anonymous>

The error tells me to run npm install, which I do on the second last line of the dockerfile. Also I checked for chromium and it is actually installed under: puppeteer > .local-chromium > win64-579032 > chrome-win32

Any help?

EDIT: I also added an extension to my jsreport config.json, so it starts chromium without a sandbox.

You need to configure jsreport/puppeteer to use the binary you explicitly downloaded using apt-get install -y google-chrome-unstable. This is done through

ENV chrome:launchOptions:executablePath google-chrome-unstable

I recommend to take a look on the official jsreport images. You would find it there. https://hub.docker.com/r/jsreport/jsreport/

The dockerfiles can be found in the jsreport repository
