Dockerfile and example test

Resources in this project

Simplest implemetation is to just pull from Docker hub

docker pull chucklapress/chrome:latest

current version latest

What's in the image

This is a bloat Ubuntu 18.04 image with a full on Python3 development suite
The image includes Chromedriver meant to be run headless.

docker run -it <image> /bin/bash

Then:

./answer.py

I made the python script executable from the command line results in file added named flavors.txt with current gelato flavors

Feel free to add your own selenium tests

import time
from lxml import html
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--window-size=1420,1080')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome(chrome_options=chrome_options)
"""
your call as to what you'd like to build in here
"""

IMPORTANT TO NOTE chrome_options.add_argument('--disable-dev-shm-usage') needed to run
Chrome seem to crash in Docker containers on certain pages due to too small /dev/shm. So you may have to fix the small /dev/shm size.

UPDATE 05/23/2020 Streamlined again to not require the additional time for switching to i-frame as web owner eliminated that, also limited selections on scrape due to corona pandemic

You will definately need to massage and play with the environment, most recent
changes are the additions of:

import os
import locale
os.environ["PYTHONIOENCODING"] = "utf-8"
myLocale=locale.setlocale(category=locale.LC_ALL, locale="en_US.UTF-8")

In the answer.py script, and apt-get install -y language-pack-en
in the Dockerfile to stop any unicode to utf8 error in the call to print.
So YMMV.
