How to assign subdomain with elixir?

Hello all, Q1) how can I assign subdomain to a user from elixir code ( say when he want to create a different instance of an app)? Q2) How can I query whether a particular subdomain exists or not? I found “dig” could be a possible solution, just wanna be sure. thanks.
