Issue in executing puppeteer in headful mode in Docker

Question

I am new to puppeteer and docker. I am facing an issue while setting up puppeteer in headful mode in docker container.

Puppeteer version: 1.6.2 Platform / OS         


        

Answer 1

Check the following Dockerfile, read the comments. It should run properly.

# First, we need to make sure all dependencies are there. If you are using docker, then the important dependencies are already present on most node images. 
FROM node:8

# To run Headful mode, you will need to have a display, which is not present in a server. 
# To avoid this, we will use Xvfb, and create a fake display, so the chrome will think there is a display and run properly. 
# So we just need to install Xvfb and Puppeteer related dependencies.
RUN apt-get update && apt-get install -yq gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 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 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps xvfb

# I am going to ignore dumb-init or such for now since it will add complexities to understand what is actually needed here. 

# Assuming we are working on /app folder, cd into /app
WORKDIR /app

# Copy package.json into app folder
COPY package.json /app

# Install dependencies
RUN npm install 

COPY . /app

# Start server on port 3000
EXPOSE 3000

# I'll also assume you are going to use root user, 
# and your script has `--no-sandbox` and `--disable-setuid-sandbox` arguments.
# We run a fake display and run our script.
# Start script on Xvfb
CMD xvfb-run --server-args="-screen 0 1024x768x24" npm start

Then I run it with following command,

# build the app
sudo docker build -t app . 

# start the container, expose to network and remove after running
sudo docker run --network=host -it app

Sample result from our script that I used above, it can be any script,

Step 8/8 : CMD xvfb-run --server-args="-screen 0 1024x768x24" npm start
