Configuration
#############

Canaille can be configured either by a environment variables, environment file, or by a configuration file.

Configuration file
==================

The configuration can be written in `toml` configuration file which path is passed in the :envvar:`CONFIG` environment variable.

.. code-block:: toml
    :caption: config.toml

    SECRET_KEY = "very-secret"

    [CANAILLE]
    NAME = "My organization"

    [CANAILLE_SQL]
    DATABASE_URI = "postgresql://user:password@localhost/database"
    ...

You can have a look at the :ref:`example file <references/configuration:Example file>` for inspiration.

Environment variables
=====================

In addition, parameters that have not been set in the configuration file can be read from environment variables.
The way environment variables are parsed can be read from the `pydantic-settings documentation <https://docs.pydantic.dev/latest/concepts/pydantic_settings/#parsing-environment-variable-values>`_.

Environment file
================

Any environment variable can also be written in a ``.env``, and will be read if present.

    Secret parameters
    =================

        A :envvar:`SECRETS_DIR` environment variable can be passed as an environment variable, being a path to a directory in which are stored files named after the configuration settings.

        For instance, you can set ``SECRETS_DIR=/run/secrets`` and put your secret key in the file ``/run/secrets/SECRET_KEY``.
