Good point, Lukas. Thank you for the clarification regarding production. I amended the article to remove the part that could cause confusion.

The :http :port key defines which port cowboy will bind to. In a default phoenix 1.4/1.5 project, for production that is configured in prod.secred.exs.

The :url key specifies what url and port the public-facing production application will be running under, mainly used for URL Helpers, websockets and the like. This doesn’t always have to match the configuration set in :http, mainly when the application is running inside a container of behind a reverse proxy.
