Laravel Dusk is not working on Docker/ docker-compose.yaml - laravel

Question

I am working on a Laravel project. I started writing browser tests using Dusk. I am using docker as my development environment. When I run the tests, I am getting the "Connection refused" error.
This is my docker-compose.yaml file.
version: '3'
services:
apache:
container_name: res_apache
image: webdevops/apache:ubuntu-16.04
environment:
WEB_DOCUMENT_ROOT: /var/www/public
WEB_ALIAS_DOMAIN: restaurant.localhost
WEB_PHP_SOCKET: php-fpm:9000
volumes: # Only shared dirs to apache (to be served)
- ./public:/var/www/public:cached
- ./storage:/var/www/storage:cached
networks:
- res-network
ports:

- "443:443"
php-fpm:

container_name: res_db

environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: restaurant
MYSQL_USER: restaurant
MYSQL_PASSWORD: secret
volumes:

environment:

cap_add:
- "SYS_ADMIN"
networks:
res-network:
driver: "bridge"
volumes:
res-data:
driver: "local"
The following is the driver function in DuskTestCase.php class
/**
* Create the RemoteWebDriver instance.
*
* #return \Facebook\WebDriver\Remote\RemoteWebDriver
*/
protected function driver()
{
$options = (new ChromeOptions)->addArguments([
'--disable-gpu',
'--headless',
'--window-size=1920,1080',
]);
return RemoteWebDriver::create(
'http://localhost:9515', DesiredCapabilities::chrome()->setCapability(
ChromeOptions::CAPABILITY, $options
)
);
}
I run the tests running the following command.
docker-compose exec php-fpm php artisan dusk
Then I get the following error.
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"capabilities":{"firstMatch":[{"browserName":"chrome","goog:chromeOptions":{"args":["--disable-gpu","--headless","--windo
w-size=1920,1080"]}}]},"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"args":["--disable-gpu","--headless","--window-size=1920,1080"]}}}
Failed to connect to localhost port 9515: Connection refused

What is wrong with my configuration and how can I fix it?
