Overview of the Dependency Injection Container and Services. Overview of container, injection, and services The Services and Dependency Injection Container concepts have been adopted by Drupal from the Symfony framework. A "service" (such as accessing the database, sending email, or translating user interface text) is defined (given a name and an interface or at least a class that defines the methods that may be called), and a default class is designated to provide the service. These two steps
