I think the way Gigalixir works (and also Heroku, [Render.com](http://Render.com) etc) is that they provide you the SSL layer for you, and in your own application you should only be concerned with HTTP layer, and maybe a redirect from HTTP to HTTPS.

So you set up your application the usual way, with listening only over HTTP on $PORT, then add custom domains in Gigalixir and set up redirect - all without changing anything in your code, but rather by altering the Gigalixir configuration with it’s CLI:
