Minimal Headless Chrome Docker Images built on Alpine Linux
Based on zenika/alpine-node
We often need a headless chrome. We created this image to get a fully headless chrome image. Be careful to the "--no-sandbox" flag from Chrome
Launch the container using:
docker container run -it --rm zenika/alpine-chrome and use the --no-sandbox flag for all your commands.
Be careful to know the website you're calling.
Explanation for the no-sandbox flag in a quick introduction here and for More in depth design document here
Launch the container using:
docker container run -it --rm --cap-add=SYS_ADMIN zenika/alpine-chrome
This allows to run Chrome with sandboxing but needs unnecessary privileges from a Docker point of view.
Thanks to ever-awesome Jessie Frazelle seccomp profile for Chrome.
Also available here wget https://raw.githubusercontent.com/jfrazelle/dotfiles/master/etc/docker/seccomp/chrome.json
Launch the container using:
docker container run -it --rm --security-opt seccomp=$(pwd)/chrome.json zenika/alpine-chrome
The default entrypoint does the following command: chromium-browser --headless --disable-gpu
You can get full control by overriding the entrypoint using: docker run -it --rm --entrypoint "" zenika/alpine-chrome chromium-browser ...
Command (with no-sandbox): docker container run -d -p 9222:9222 zenika/alpine-chrome --no-sandbox --remote-debugging-address=0.0.0.0 --remote-debugging-port=9222 https://www.chromestatus.com/
Open your browser to: http://localhost:9222 and then click on the tab you want to inspect. Replace the beginning

by

With tool like ("Puppeteer")[https://pptr.dev/#?product=Puppeteer&version=v1.5.0&show=api-class-browser], we can add a lot things with our Chrome Headless.
With some code in NodeJS, we can improve and make some tests.
See the "with-puppeteer" folder for more details.
If you have a NodeJS/Puppeteer script in your current folder named my-test.js, you can launch it using the following command:
docker run -it --rm -v $(pwd):/usr/src/app --cap-add=SYS_ADMIN zenika/alpine-chrome:with-puppeteer node my-test.js
