chrome is not reachable while running the test cases from docker

[Hima Uppili]

I'm attempting to run the test cases using Selenium Python via Docker and am encountering several difficulties.

Here is tech stack information,

Selenium :4.11.2

Python Version: 3.10

Chrome driver: 116.0.5845.96

Chrome binary: 116.0.5845.96

 

Docker file:

 

RUN pip install logging-formatter-anticrlf

FROM --platform=linux/amd64 python:3.9
# Chrome dependency
WORKDIR /usr/bin

RUN apt-get update && apt-get install -y \

RUN pytest -k test_case 

Test Case:

 def test_case():from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService, Service

from selenium.webdriver.common.by import By chrome_options = webdriver.ChromeOptions()
 #s = Service(executable_path=driver_path)
 chrome_options.add_argument('--headless')
 chrome_options.add_argument('--privileged')

 chrome_options.add_argument('--no-sandbox')
 chrome_options.add_argument("--disable-setuid-sandbox")
 chrome_options.add_argument('--ignore-certificate-errors')
 chrome_options.add_argument('--disable-dev-shm-usage')# overcome limited resource problems
 chrome_options.add_argument('--disable-extensions')
 chrome_options.add_argument('--disable-gpu')
 chrome_options.add_argument("--remote-allow-origins=*")
 chrome_options.add_argument("--remote-debugging-port=9222")  # this

 chrome_options.add_experimental_option(
     "prefs", {"profile.default_content_setting_values.notifications": 1}
 )
 driver = webdriver.Chrome(options=chrome_options)
 driver.get(“www.google.com”) 

When I run the test case in local it is working fine without any issues  But same test case is failing when running in the docker:  

I also tried the following methods:             

  1. Avoid pre-installation of driver and binary; instead, let Selenium Manager handle the installation; the installation took place in the root directory and still produced the same issue.               2. Downloaded the Chrome drivers into a folder and entered the executable path in service (same issue as before) I experimented with different options and capabilities, as well as lowering the selenium and driver versions.Is there anything I'm missing in the docker file to support the chrome binary file? Any assistance would be greatly appreciated.

For docker run, you need to initiate the webdriver in a specific port, and then the driver needs to be initiated using the remote keyword.
For example:
Docker:

docker pull selenium/standalone-chrome
docker run -d -p 4444:4444 --name selenium-new selenium/standalone-chrome:latest

Driver:

driver = webdriver.Remote(
command_executor="http://localhost:4444/wd/hub",
options=c_options
)

I hope this will help you.
