Seleniun Docker in Python Enviroment

This repo will guide through the tutorial to run headless chrome selenium driver inside your docker container. To make the process more simple we have setup docker-compose to build container with single command. Below is step by step guide to setup container and also python shell example to get page source of google.com using selenium.

   # add your current user to Docker group
   $ sudo usermod -aG docker $USER

2. Install docker-compose

   $ sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
   $ sudo chmod +x /usr/local/bin/docker-compose

3. Clone repo and build and up container

   $ git clone https://github.com/upraisedco/python-selenium-docker.git
   $ cd python-selenium-docker
   $ docker-compose up --build -d

4. Command to get inside docker

   $ docker exec -it python-selenium-docker_selenium_1 bash

Python shell example inside container

# tutorial to get page source of google.com
>>> from selenium import webdriver
>>> chrome_options = webdriver.ChromeOptions()
>>> chrome_options.add_argument('--no-sandbox')
>>> chrome_options.add_argument('--headless')
>>> chrome_options.add_argument('--disable-gpu')
>>> driver = webdriver.Chrome(chrome_options=chrome_options)
>>> driver.get('http://www.google.com')
>>> print(driver.page_source)
