I know of a bunch of apps that deploy to multiple servers behind a load balancer using Kamal. Here's an article explaining the process https://guillaumebriday.fr/how-to-deploy-and-scale-your-rail...

The article only talking about single app per server without using hostnames. That you can do as the app will respond to the IP address. Currently you can't run multiple apps on each servers behind load balancer as the health check will not be successful as there is no way to set the default host.
