Failing Docker tests when running on M2 mac

[evan1108]

I cloned the SeleniumBase repo, built the docker image docker build --platform linux/amd64 -t seleniumbase ., and ran the test docker run --platform linux/amd64 seleniumbase ./run_docker_test_in_chrome.sh I get an error saying Chrome has failed to start/crashed. I haven't made any changes to the Dockerfile. I've tried running the test without the --platform tag in the docker run command and that fails as well. Running on an M2 mac.

I'm attempting to create my own Docker image with SeleniumBase but I'm getting the following error:

File "/usr/local/lib/python3.8/dist-packages/selenium/webdriver/common/service.py", line 115, in assert_process_still_running
raise WebDriverException(f"Service {self._path} unexpectedly exited. Status code was: {return_code}")
selenium.common.exceptions.WebDriverException: Message: Service /root/.cache/selenium/chromedriver/linux64/123.0.6312.122/chromedriver unexpectedly exited. Status code was: 127

This is after copying most parts of the standard Dockerfile (minus the chrome and webdriver installs as I understand Seleniumbase / Selenium Manager handles that)

Dockerfile:

FROM ubuntu:20.04

CMD python3 ./src/manage.py migrate && python3 ./src/manage.py selenium_worker

The entrypoint command is executing this:

class Command(BaseCommand):
	def handle(self, *args, **options):
		with SB("dummy") as sb:
			print("Initializing global web driver")
			settings.GLOBAL_WEB_DRIVER = sb

Which is what I see failing in the stack trace:

Operations to perform:
  Apply all migrations: admin, auth, contenttypes, django_rq, sessions, socials
Running migrations:
  No migrations to apply.

Appreciate any direction you can provide!

I'm still working on updating the included Dockerfile. Maybe you'll get it working before I do.

This was resolved in 4.25.4 - https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.25.4

[evan1108]

You are incredible @mdmintz! Confirmed it's working on my end. Thanks for the quick attention and fix.
