Default Language

The installation-wide default language is set with the APP_DEFAULT_LOCALE environment variable. This determines the language users see if they haven’t chosen their own language preference.

Supported values

Value	Language
en	English
et	Estonian
uk	Ukrainian

Configuration

Set APP_DEFAULT_LOCALE wherever you define your app’s environment variables.

Using docker-compose.yml

services:
  kordon-app:
    image: kordon-app:latest
    environment:
      APP_DEFAULT_LOCALE: et

Using a .env file

APP_DEFAULT_LOCALE=et

Fallback order

For authenticated requests, Kordon resolves the language in this order:

1. X-Kordon-Locale request header
2. User’s saved locale preference
3. APP_DEFAULT_LOCALE
4. Browser Accept-Language header
5. en

APP_DEFAULT_LOCALE sets the default for the whole installation, but any user who has chosen their own language in their profile will override it.

If APP_DEFAULT_LOCALE is missing or set to an unsupported value, Kordon falls back to en.
