About headless

This is a version of the simple example but with the chromedp settings changed to use the docker knqz/chrome-headless image.

Running

# retrieve docker image
docker pull knqz/chrome-headless

# start chrome-headless
docker run -d -p 9222:9222 --rm --name chrome-headless knqz/chrome-headless

# run chromedp headless example
go build && ./headless
