In Multisite setup the custom page '/speakers' should available on domain1 site only

Question

I have Multi-site setup , want to make available custom page say '/speakers' on domain1 site but not on domain2 site

I have tried to figured out in routing.yml file to check is there way to pass any variable in route where I can define that route should available for specific domain only, even I tried with the alter routes approach as well but no luck.

Note: Both sites has same custom module installed.

Answer 1

Just for record purpose, posting answer:

I used alter routes() approach in which used remove function w.r.t to domain condition:

  $collection->remove('route_name'); 

Created: module_name.services.yml (root of custom module)

module_name.route_subscriber:
    class: Drupal\module_name\Routing\RouteSubscriber
    tags:
      - { name: event_subscriber }  

Created: RouteSubscriber.php (module_name\src\Routing)

<?php
  namespace Drupal\module_name\Routing;
  use Drupal\Core\Routing\RouteSubscriberBase;
  use Symfony\Component\Routing\RouteCollection;

  class RouteSubscriber extends RouteSubscriberBase {
 
    protected function alterRoutes(RouteCollection $collection) {
      $domain = \Drupal::request()->getHost();
      // check domain
      if($domain == 'domain_name'){
        if ($collection->get('route_name')) {
          // remove route conditionally
          $collection->remove('route_name');
        }
      }
    }

  }

Info: I Choose this particular approach becoz I need to enabled same module for both sites
