DrupalKernel

The DrupalKernel class is the core of Drupal itself.

This class is responsible for building the Dependency Injection Container and also deals with the registration of service providers. It allows registered service providers to add their services to the container. Core provides the CoreServiceProvider, which, in addition to registering any core services that cannot be registered in the core.services.yaml file, adds any compiler passes needed by core, e.g. for processing tagged services. Each module can add its own service provider, i.e. a class implementing Drupal\Core\DependencyInjection\ServiceProvider, to register services to the container, or modify existing services.
