When trying to use the selenium/standalone-chrome image with rails I got a very annoying error and the cause is still unknown. But it was resolved by replacing it with another image.

Here is what happened.

Environment

# docker-compose.yml

version: '3.9'
services:
  web:
    # ...
  db:
    # ...
  webdriver_chrome:
    image: selenium/standalone-chromium:117.0
    ports:
      - 4444:4444
      - 5900:5900

# spec/support/capybara.rb

Capybara.register_driver :remote_chrome do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument('--headless')
  options.add_argument('--no-sandbox')
  options.add_argument('--disable-dev-shm-usage')
  options.add_argument('--window-size=1400,1400')

  Capybara::Selenium::Driver.new(
    app,
    browser: :remote,
    url: ENV['SELENIUM_REMOTE_HOST'],
    options:
  )
end

RSpec.configure do |config|
  config.before(:each, type: :system) do
    driven_by :rack_test
  end

  config.before(:each, type: :system, js: true) do
    if ENV['SELENIUM_REMOTE_HOST'].present?
      Capybara.server_host = IPSocket.getaddress(Socket.gethostname)
      Capybara.app_host = "http://#{Capybara.server_host}"
      driven_by :remote_chrome
    else
      driven_by :selenium_chrome_headless
    end
  end
end

Errors

      Selenium::WebDriver::Error::SessionNotCreatedError:
        Could not start a new session. Error while creating session with the driver service. Stopping driver service: Could not start a new session. Response code 500. Message: unknown error: Chrome failed to start: crashed.
          (chrome not reachable)
          (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

How to temporarily fix it!

Replacing selenium/standalone-chromium:117.0 with seleniarm/standalone-chromium:117.0

-    image: selenium/standalone-chromium:117.0
+    image: seleniarm/standalone-chromium:117.0
