Python Selenium Crawler as Docker image

I'm looking to have a python script written which will use selenium web driver to go to a web page, click one link, allow next page to load then exit. In python set a user agent, allow cookies etc just like a real browser. The script must use chromedriver. Also you will write a small Docker fie for this so that all dependencies are built within the container. When docker run is executed the entry script will execute the python script which will go to the webpage and click the link My budget is less than $50 USD
