Is there any way to automatically create subdomain for each node from some content type?
I have a lot of pages that should be created and each should be on separated subdomain, I'm trying to find the way to do that through current website on Drupal 8.
You could use an outbound path processor and modify $options['base_url'], see LanguageNegotiationUrl::processOutbound. This method is from a language negotiation plugin, but you can place directly in a service tagged path_processor_outbound, see Global preprocess for all links
