Custom domain for saas supported?

[nmajorcarebit]

Does the kamal proxy support custom domains? For example if I was building a rails SaaS like shopify I want customers to be able to connect their own domains and issue SSL certs for them.

From what I can tell the domains are defined by the configuration, this would require some kind of runtime changes to the domains the kamal proxy is listening for. Also probably a way for kamal to look at a database to find the domains that are supported.

I think you could get around this by using something like Cloudflare for SaaS, but in the spirit of No PaaS, I wonder if this is something supported or on the roadmap.

Thanks!
