Environment variable is not accessible during application boot

Questions / Help

Hi,

I’ve set APPLICATION_HOST variable in the fly.toml and trying to fetch it during application but in config/runtime.exs (Phoenix) but it fails

[env]
  APPLICATION_HOST = "myapp-stg.fly.dev"

config :my_app, MyAppWeb.Endpoint,
    url: [host: System.get_env!("APPLICATION_HOST"), ...

However, if I hardcode that variable and the application completes the boot process, I can see it in the env output.

NVM - there is no System.get_env! :slight_smile:
