Yaml support for Pydantic settings

Project description


Yaml support for Pydantic settings. Load a yaml config file as nested Pydantic models.

Allows to use file:xxxx placeholders in the yaml config file for secrets. A placeholder is replaced with the contents of the file. Paths are relative to the 'secrets_dir' setting (see below).


$cat /config/config.yaml

  password: <file:database_password>
  username: my_database_username

$cat /secrets/database_password


Python code example:

    from pydantic import BaseModel
    from pydantic_settings_yaml import YamlBaseSettings

    class Database(BaseModel):
        username: str
        password: str

    class Settings(YamlBaseSettings):
        database: Database

        class Config:
            secrets_dir = "/secrets"
            yaml_file = "/config/config.yaml"

    settings = Settings()

    assert settings.dict() == {
        "database": {
            "password": "my_secret_database_password", 
            "username": "my_database_username"
