php - How to inject a repository into a service in Symfony?

Question

I need to inject two objects into ImageService. One of them is an instance of Repository/ImageRepository, which I get like this:

$image_repository = $container->get('doctrine.odm.mongodb')
    ->getRepository('MycompanyMainBundle:Image');

So how do I declare that in my services.yml? Here is the service:

namespace MycompanyMainBundleServiceImage;

use DoctrineODMMongoDBDocumentRepository;

class ImageManager {
    private $manipulator;
    private $repository;

    public function __construct(ImageManipulatorInterface $manipulator, DocumentRepository $repository) {
        $this->manipulator = $manipulator;
        $this->repository = $repository;
    }

    public function findAll() {
        return $this->repository->findAll();
    }

    public function createThumbnail(ImageInterface $image) {
        return $this->manipulator->resize($image->source(), 300, 200);
    }
}

Here is a cleaned up solution for those coming from Google like me:

Update: here is the Symfony 2.6 (and up) solution:

services:

    myrepository:
        class: DoctrineORMEntityRepository
        factory: ["@doctrine.orm.entity_manager", getRepository]
        arguments:
            - MyBundleEntityMyClass

    myservice:
        class: MyBundleServiceMyService
        arguments:
            - "@myrepository"

Deprecated solution (Symfony 2.5 and less):

services:

    myrepository:
        class: DoctrineORMEntityRepository
        factory_service: doctrine.orm.entity_manager
        factory_method: getRepository
        arguments:
            - MyBundleEntityMyClass

    myservice:
        class: MyBundleServiceMyService
        arguments:
            - "@myrepository"
