Module: Brainiac::Plugins::Fizzy::EnvUrl

Defined in:
lib/brainiac/plugins/fizzy/env_url.rb

Overview

Derives the public URL of an ephemeral Belt environment from its terraform.tfvars. Kept separate from Helpers so the pure URL/HCL logic stays small and independently testable.

Class Method Details

.for_card(card_number) ⇒ Object

URL of the ephemeral Belt environment for a card, if one is active. The env name is fizzy-<card_number>; the public URL is derived from the env's terraform.tfvars, matching the frontend_urls convention in the Belt infra module:

parent set -> https://<env>.<parent>.<domain>
prod       -> https://<domain>
otherwise  -> https://<env>.<domain>
