Environment Variables - Docs

The [env] section allows you to define environment variables that will be available to your application at runtime.

These variables are injected into all the processes of your application.

# Configuration file with an env section
app = 'myapp'

[env]
  APP_DEBUG = 'false'
  DB_HOST = 'my-db-service'

Secrets

Sensitive data, such as passwords and keys, must be stored in Secrets, not in environment variables.
