Pydantic Config not worked

This is expected behavior. Your config is not bound to the container at this stage yet, neither it is loaded from your pydantic settings. Use application.config.from_pydantic(config) instead of application.override_providers(config=config).

One of:

1. Keep Configuration provider only at the top-level container (MainApplication) and use Dependency provider to pass config values down.
2. Explicitly load configs for each sub-container: application.services.config.from_pydantic(config)

I don't understand you, what's the problem with making a normal configuration, why is it so inconvenient

what's the problem with making a normal configuration

If you have ideas how to do it better, please send PR.

why is it so inconvenient

Configuration provider was made to be used in declarative fashion. If you do not need it, just replace config = providers.Configuration() with config = providers.Factory(get_config).

Configuration provider was made to be used in declarative fashion. If you do not need it, just replace with .config = providers.Configuration()``config = providers.Factory(get_config)

None of your ideas worked for me. You don't seem to have checked it out.

I need fully reproducible example to assist you further. Note: by fully I mean something I can copypaste and run with python without any modifications. Code you provided in the issue description is not sufficient.
