google chrome headless (and friends)

This image is mainly for automated testing. It provides:

• Chrome headless
• Lighthouse
• Wappalyzer
• cypress

Intsalling all of these packages makes the image huge (1.3 GB) :-( It's currently based on Ubuntu 20.04, we've also tried Alpine, but this results in only 100 MB less. Diskspace is mainly eaten up by Node-Dependecies (350 MB), Cypress (500 MB) and Google Chrome (200 MB). We're open to suggestions how to minimize this.

example usage

# save technologies to json file

# get lighthouse report as json on stdout
docker run -ti --rm scalecommerce/chrome-headless lighthouse --output json --output-path stdout https://www.google.com/


# don't limit network and emulate desktop
docker run -ti --rm -v $(pwd):/opt/reports scalecommerce/chrome-headless lighthouse https://www.google.com/ --throttling-method provided --preset desktop
