Selenium python and docker

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

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 

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

services:
  bot:
    build: selenium-test

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)

You can then use a undetected_chromedriver as selenium like this:

self.driver.execute_script("console.log("Hello")
