Now that coder supports wildcard domains, it would be awesome if we could add the ability to pre-define subdomains in the terraform config to particular ports/addresses.

The use case that we have is that we are developing a multi-tenanted app where each tenant has their own unique subdomain a-lahttps://tenant1.ourapp.com,https://tenant2.ourapp.com.

Right now, we have a real sketchy netcat listener that gets curl'd and then updates nginx config when new workspaces get spun up. It would be great if we could specify a default subdomain where the coder_agent could be accessed at and be able to define other subdomains that would point to this agent.

I think this would be advantageous to all companies who are developing apps that run on multiple subdomains.

Please let me know what you think.
