title: Configuration
description: The available configuration options when setting up Koito.
---

Koito is configured using **environment variables**. This is the full list of configuration options supported by Koito.

The suffix `_FILE` is also supported for every environment variable. This allows the use of Docker secrets, for example: `KOITO_DATABASE_URL_FILE=/run/secrets/database-url` will load the content of the file at `/run/secrets/database-url` for the environment variable `KOITO_DATABASE_URL`.

:::caution
If the environment variable is defined without **and** with the suffix at the same time, the content of the environment variable without the `_FILE` suffix will have the higher priority.
