pup-scraper

Dockerized pup used for scraping HTML

Usage

If you want to build the Docker image yourself and run it ::

• run docker build -t my-pup-scraper . to build the Docker image
• run docker run --rm -e URL='http://www.google.com' -e FILTER='body' my-pup-scraper to create a Docker container and run pup
  • --rm
    • removes/deletes the container after it finishes running
  • -e URL='http://www.google.com
    • sets an environment variable named URL to the value http://www.google.com (change this to whatever url you need to scrape)
  • -e FILTER='body'
    • sets an environment variable named FILTER to the value body (change this to whatever HTML/CSS selectors you need to scrape)

Or if you want to just run the Docker image stored in DockerHub ::

• run docker run --rm -e URL='http://www.google.com' -e FILTER='body' jeffreywallace81/pup-scraper

Notes

• If you want to ignore all of the HTML tags and just extract the raw text, you can run the command like this ::
  • docker run --rm -e URL='http://www.google.com' -e FILTER='body text{}' my-pup-scraper
• For an example of a more complex HTML/CSS selector, go look at the default value for the FILTER environment variable in the Dockerfile. REF
