Two Rails projects on two different droplets with single domain
Is it possible to use one domain for two Rails projects on two different droplets?
I have two droplets with two different Rails 5 projects (ubuntu 18, nginx, puma). One for the website and another for API (backend for mobile app).
I mean that I want to buy example.com domain. After that, I want to use example.com for website and api.example.com for API. I think that I should make some work with nginx config? Should I use private IP? Which droplet should process traffic depending on url?
