Dockerfile

# Note that there is also an official puppeteer docker image available
# However that is AMD64 only, so cannot be used on silicon based macs
# So we are building our own here, but will also provide a link to the
# official image in case we change our minds https://pptr.dev/guides/docker

# This Dockerfile is a combination (with minor modifications) of `Dockerfile`,
# `with-node/Dockerfile` and `with-puppeteer/Dockerfile` found on
# https://github.com/Zenika/alpine-chrome
