Laravel/Dusk not running in Docker

I have a clean custom docker image, which is built off of the base PHP:Apache image. In my dockerfile, I'm installing Google Chrome and and XVFB. Once I have Laravel up and running, I follow the Laravel Dusk installation instructions located here: https://laravel.com/docs/5.4/dusk#installation

I then run "php artisan dusk" inside of the docker container, and I get this error:

PHPUnit 5.7.17 by Sebastian Bergmann and contributors.

E                                                                   1 / 1 (100%)

There was 1 error:

After poking around a bit, I tried running "vendor/laravel/dusk/bin/chromedriver-linux", which gives me this error message:

Starting ChromeDriver 2.25.426924 (649f9b868f6783ec9de71c123212b908bf3b232e) on port 9515

I have tried multiple solutions located in the GitHub error ticket, with no success. Has anyone been able to run "php artisan dusk" inside of Docker container successfully?
