Example on how to config google cloud storage with KnpGaufetteBundle - symfony

Question

I am trying to configure a KnpGaufretteBundle to use Google Cloud Storage for storing my files. This is the config:
## definition of the GCS service
app.google_cloud_storage.service:
class: \Google_Service_Storage
factory_class: Knp\Bundle\GaufretteBundle\DependencyInjection\Factory\GoogleCloudStorageAdapterFactory
factory_method: 'create'
arguments:
- "123#developer.gserviceaccount.com"
- "http://localhost/file.p12"
- "pwd"
## config of knp_gaufrette
knp_gaufrette:
stream_wrapper: ~
adapters:
gcs_minn_images:
google_cloud_storage:
service_id: 'app.google_cloud_storage.service'
bucket_name: 'minn-images'
filesystems:
gcs_minn_images_fs:
adapter: gcs_minn_images
The error message I got is:
ContextErrorException in GoogleCloudStorageAdapterFactory.php line 16:
Catchable Fatal Error: Argument 1 passed to Knp\Bundle\GaufretteBundle\DependencyInjection\Factory\GoogleCloudStorageAdapterFactory::create() must be an instance of Symfony\Component\DependencyInjection\ContainerBuilder, string given, called in /home/amine/NetBeansProjects/tuto/app/cache/dev/appDevDebugProjectContainer.php on line 724 and defined
According to the error message, I gave a string of stead of ContainerBuilder. Great! Let's add the ContainerBuilder to the arguments as follows:
## definition of the GCS service
app.google_cloud_storage.service:
class: \Google_Service_Storage
factory_class: Knp\Bundle\GaufretteBundle\DependencyInjection\Factory\GoogleCloudStorageAdapterFactory
factory_method: 'create'
arguments:
- #service_container
- "123#developer.gserviceaccount.com"
- "http://localhost/file.p12"
- "pwd"
The result is again an error:
Catchable Fatal Error: Argument 1 passed to Knp\Bundle\GaufretteBundle\DependencyInjection\Factory\GoogleCloudStorageAdapterFactory::create() must be an instance of Symfony\Component\DependencyInjection\ContainerBuilder, instance of appDevDebugProjectContainer given, called in /home/amine/NetBeansProjects/tuto/app/cache/dev/appDevDebugProjectContainer.php on line 724 and defined
So now, the error is telling me that I provide an instance of appDevDebugProjectContainer in stead of ContainerBuilder!!
Ok, let's have a look to /home/amine/NetBeansProjects/tuto/app/cache/dev/appDevDebugProjectContainer.php on line 724...
class appDevDebugProjectContainer extends Container{
// ...
/**
* Gets the 'app.google_cloud_storage.service' service.
*
* This service is shared.
* This method always returns the same instance of the service.
*
* #return \Google_Service_Storage A Google_Service_Storage instance.
*/
protected function getApp_GoogleCloudStorage_ServiceService()
{
return $this->services['app.google_cloud_storage.service'] =\Knp\Bundle\GaufretteBundle\DependencyInjection\Factory\GoogleCloudStorageAdapterFactory::create($this, '123#developer.gserviceaccount.com', 'http://localhost/file.p12', 'pwd');
}
I am really lost...
So, is there any complete example to config google cloud storage?

I finally found the solution. You have to create your own factory class as described in the documentation of the bundle:
Factory class
<?php
namespace Minn\AdsBundle\Factory;
/**
* Description of GoogleCloudStorageServiceFactory
*/
class GoogleCloudStorageServiceFactory {
public function createService() {
// creating the google client
$client = new \Google_Client();
// setting the service acount credentials
$serviceAccountName = '123#developer.gserviceaccount.com';
$scopes = array(
'https://www.googleapis.com/auth/devstorage.read_write',
);
$privateKey = file_get_contents('http://localhost/f.p12');
$privateKeyPassword = 'pwd';
$credential = new \Google_Auth_AssertionCredentials(
$serviceAccountName, $scopes, $privateKey, $privateKeyPassword);
// set assertion credentials
$client->setAssertionCredentials($credential);
// creating and returning the service
return new \Google_Service_Storage($client);
}
}
The config.yml file
app.google_cloud_storage.service:
class: \Google_Service_Storage
factory: [Minn\AdsBundle\Factory\GoogleCloudStorageServiceFactory, createService]
knp_gaufrette:
stream_wrapper: ~
adapters:
gcs_images:
google_cloud_storage:
service_id: 'app.google_cloud_storage.service'
bucket_name: 'images'
filesystems:
gcs_images_fs:
adapter: gcs_images
vich_uploader:
db_driver: orm
storage: gaufrette
mappings:
motors_files:
upload_destination: gcs_images_fs
namer: vich_uploader.namer_origname
delete_on_remove: true
That's was it...
Hope it will help others...
