I'm using the Wodby docker stack for the development of a web application. One requirement is to have a Drupal multisite, so I need Apache to not only listen to project.localhost, but also to another sudomain, i. e., subdomain.project.localhost. The key to this is traefik: It routes every request, so it needs to now the new route to Apache. It is possible to add a comma-separated list of hostnames to the traefik.frontend.rule label of Apache, i. e.

'traefik.frontend.rule=Host:${PROJECT_BASE_URL},subdomain.${PROJECT_BASE_URL}'
