[FIXED] Issue running chrome driver in docker image

Issue

I have written some scripts to extract some data from website using selenium. Although my code runs well outside of docker container, it fails when I run it after building an image. I searched through the google and looked over the internet to find the similar issue but could not find something similar. Here I have posted my docker file,

# syntax=docker/dockerfile:1

FROM python:latest

WORKDIR /Users/ufomammut/Documents/eplrestapi
COPY requirements.txt requirements.txt

RUN pip3 install -r requirements.txt
RUN curl https://chromedriver.storage.googleapis.com/90.0.4430.24/chromedriver_linux64.zip -O
RUN unzip chromedriver_linux64.zip 

COPY . .


CMD [ "python3", "epl.py"]

The error message I receive when I run the docker image that I built,

 Traceback (most recent call last):
  File "/Users/ufomammut/Documents/eplrestapi/epl.py", line 172, in <module>
    browser = webdriver.Chrome("./chromedriver",options = chr_options)
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/common/service.py", line 98, in start
    self.assert_process_still_running()
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/common/service.py", line 109, in assert_process_still_running
    raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: Service ./chromedriver unexpectedly exited. Status code was: 255

In my code I have provided the path to the chromedriver as follows:

browser = webdriver.Chrome("./chromedriver",options = chr_options)

Right now I used linux arm64 python base image and was able to curl and unzip the chromedriver as reflected in my dockerfile above.I am no longer receiving the format error but I am receiving this error message as I posted above where it says the chromedriver unexpectedly exited.

Solution

You appear to have copied a chromedriver binary built for MacOS into a Debian machine. Based on how you've tagged this question with macos and the image python:3.9.5-slim-buster you are using is amd64 based on Debian.

I suggest you continue persisting with trying to curl the Linux 64 bit chromedriver into your machine via your Dockerfile.

To test it in your host OS you can simply change your current chromedriver binary to chromedriver.bakup. Download the linux version to chromedriver and rebuild your docker machine and it will copy the linux version into the new image.
