Hey Felipe,

I think the error that you are getting is when the system test is trying to connect to the chrome driver in the separated container and failed.

I think this can help you by updating this file application_system_test_case.rb

require "test_helper"
require "socket"


def prepare_options
  driver_options = {
    desired_capabilities: {
      chromeOptions: {
        args: %w[headless disable-gpu disable-dev-shm-usage]
      }
    }
  }

  driver_options[:url] = ENV['selenium_remote_url'] if ENV['selenium_remote_url']

  driver_options
end

class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
  driven_by :selenium, using: :chrome, screen_size: [1400, 1400],
            options: prepare_options
end

Take attention to the code that fetch the selenium_remote_url from the env variable
