Running in Docker

deathgaze

I'm leaving this here in case anyone finds it useful!

It took me about a day of work to figure it out, but I finally got a working Dockerfile for launching jsreport as a package in my Node.js package. This example uses PM2 to launch the process, but node <file> should work fine too.

FROM node:8

### START Puppeteer Dependencies
# See this link for details:
# https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md

# See https://crbug.com/795759
RUN apt-get update && apt-get install -yq libgconf-2-4

# Install latest chrome dev package and fonts to support major charsets (Chinese, Japanese, Arabic, Hebrew, Thai and a few others)
# Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer
# installs, work.

# It's a good idea to use dumb-init to help prevent zombie chrome processes.

RUN chmod +x /usr/local/bin/dumb-init

# Uncomment to skip the chromium download when installing puppeteer. If you do,
# you'll need to launch puppeteer with:
#     browser.launch({executablePath: 'google-chrome-unstable'})
# ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

# Install puppeteer so it's available in the container.
RUN npm i puppeteer

### END Puppeteer Dependencies ###

RUN npm install pm2 -g

RUN mkdir -p /app
WORKDIR /app

# Build deps separately so hopefully we won't have to rebuild them
ADD ./jsreport/package.json ./packages/package.json
ADD ./jsreport/yarn.lock ./packages/yarn.lock
RUN cd packages && yarn

ADD jsreport ./jsreport
RUN cp -a ./packages/node_modules ./jsreport/node_modules

ADD ecosystem.config.json .

### START Puppeteer Dependencies
ENTRYPOINT ["dumb-init", "--"]
### END Puppeteer Dependencies ###


ENV chrome:launchOptions:args --no-sandbox
CMD [ "pm2-runtime", "start", "ecosystem.config.json"]

thanks for the tips and for sharing your work.

just to clarify for anyone, the steps above are useful when you want to build your own docker image, probably because you want to run jsreport and your app in same container or because you want to change some step in the docker build process.

we deploy docker images for each release of jsreport, so if someone wants to just quickly try jsreport or maybe deploy jsreport as standalone container it is recommend to use our docker images. more information here, our docker images are useful too as a reference to build custom images

Hi,

I want to create a Dockerfile for launching jsreport as a package in my Node.js package. Currently, it is throwing errors like not able to launch the chrome browser.
Please provide a quick help. I am having jsrepot.config.json file in the project. index.js as the starting file. script to build the application is node index.js

Thanks
