Selenium python and docker

#python #docker #selenium

Hi, I show how I use selenium (or undetected_chromedriver) in a docker container.

I - Dockerfile

I'm using a docker python image and adding chromdriver and chromium to browse a website.

The first step is to create the requirements.txt file. Personally, I use the undetected-chromedriver library, which takes selenium

undetected-chromedriver==3.5.5
Enter fullscreen mode Exit fullscreen mode 
FROM python:3.10 COPY ../.. . RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - RUN sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list' RUN apt-get -y update RUN apt-get install -y chromium # install chromedriver RUN apt-get install -yqq unzip RUN wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip RUN unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/ ENV DISPLAY=:99 RUN pip install -r requirements.txt CMD python -u app.py
Enter fullscreen mode Exit fullscreen mode

You can then run this Dockerfile in a docker-compose, for example.

services: bot: build: selenium-test
Enter fullscreen mode Exit fullscreen mode

II - Script

In the second step, I need to add two options for working in a container.

I add :

  • --no-sandbox
  • --disable-setuid-sandbox

Here is an example with python

class App: options: uc.ChromeOptions driver: uc.Chrome def __init__(self): self.options = uc.ChromeOptions() self.options.arguments.extend(["--no-sandbox", "--disable-setuid-sandbox"]) self.driver = uc.Chrome(headless=True, use_subprocess=False)
Enter fullscreen mode Exit fullscreen mode

You can then use a undetected_chromedriver as selenium like this:

self.driver.execute_script("console.log("Hello")
Enter fullscreen mode Exit fullscreen mode
