Google Cloud Storage filesystem driver for Laravel

Google Cloud Storage filesystem driver for Laravel 9 (using Flysystem v3 and its own GCS adapter).

Looking for Laravel 8 support? Use the v1 branch!

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

You can install the package via composer:

composer require spatie/laravel-google-cloud-storage

Next, add a new disk to your filesystems.php config:

'gcs' => [
    'driver' => 'gcs',
    'key_file_path' => env('GOOGLE_CLOUD_KEY_FILE', null), // optional: /path/to/service-account.json
    'key_file' => [], // optional: Array of data that substitutes the .json file (see below)
    'project_id' => env('GOOGLE_CLOUD_PROJECT_ID', 'your-project-id'), // optional: is included in key file
    'bucket' => env('GOOGLE_CLOUD_STORAGE_BUCKET', 'your-bucket'),
    'path_prefix' => env('GOOGLE_CLOUD_STORAGE_PATH_PREFIX', ''), // optional: /default/path/to/apply/in/bucket
    'storage_api_uri' => env('GOOGLE_CLOUD_STORAGE_API_URI', null), // see: Public URLs below
    'api_endpoint' => env('GOOGLE_CLOUD_STORAGE_API_ENDPOINT', null), // set storageClient apiEndpoint
    'visibility' => 'public', // optional: public|private
    'visibility_handler' => null, // optional: set to \League\Flysystem\GoogleCloudStorage\UniformBucketLevelAccessVisibility::class to enable uniform bucket level access
    'metadata' => ['cacheControl' => 'public,max-age=86400'], // optional: default metadata
],

Usage

$disk = Storage::disk('gcs');

$disk->put('avatars/1', $fileContents);
$exists = $disk->exists('file.jpg');
$time = $disk->lastModified('file1.jpg');
$disk->copy('old/file1.jpg', 'new/file1.jpg');
$disk->move('old/file1.jpg', 'new/file1.jpg');
$url = $disk->url('folder/my_file.txt');
$url = $disk->temporaryUrl('folder/my_file.txt', now()->addMinutes(30));
$disk->setVisibility('folder/my_file.txt', 'public');

See https://laravel.com/docs/master/filesystem for full list of available functionality.

Authentication

The Google Client uses a few methods to determine how it should authenticate with the Google API.

If you specify a path in the key key_file in disk config, that json credentials file will be used.

If the GOOGLE_APPLICATION_CREDENTIALS env var is set, it will use that.

putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json');

It will then try load the key file from a 'well known path':
- windows: %APPDATA%/gcloud/application_default_credentials.json
- others: $HOME/.config/gcloud/application_default_credentials.json
If running in Google App Engine, the built-in service account associated with the application will be used.
If running in Google Compute Engine, the built-in service account associated with the virtual machine instance will be used.

If you want to authenticate directly without using a json file, you can specify an array for key_file in disk config with this data:

'key_file' => [
    'type' => env('GOOGLE_CLOUD_ACCOUNT_TYPE'),
    'private_key_id' => env('GOOGLE_CLOUD_PRIVATE_KEY_ID'),
    'private_key' => env('GOOGLE_CLOUD_PRIVATE_KEY'),
    'client_email' => env('GOOGLE_CLOUD_CLIENT_EMAIL'),
    'client_id' => env('GOOGLE_CLOUD_CLIENT_ID'),
    'auth_uri' => env('GOOGLE_CLOUD_AUTH_URI'),
    'token_uri' => env('GOOGLE_CLOUD_TOKEN_URI'),
    'auth_provider_x509_cert_url' => env('GOOGLE_CLOUD_AUTH_PROVIDER_CERT_URL'),
    'client_x509_cert_url' => env('GOOGLE_CLOUD_CLIENT_CERT_URL'),
],

Public URLs

The adapter implements a getUrl($path) method which returns a public url to a file.

Note: Method available for Laravel 5.2 and higher. If used on 5.1, it will throw an exception.

$disk = Storage::disk('gcs');
$url = $disk->url('folder/my_file.txt');
// http://storage.googleapis.com/bucket-name/folder/my_file.txt

If you configure a path_prefix in your config:

$disk = Storage::disk('gcs');
$url = $disk->url('folder/my_file.txt');
// http://storage.googleapis.com/bucket-name/path-prefix/folder/my_file.txt

If you configure a custom storage_api_uri in your config:

$disk = Storage::disk('gcs');
$url = $disk->url('folder/my_file.txt');
// http://your-custom-domain.com/bucket-name/path-prefix/folder/my_file.txt

For a custom domain (storage api uri), you will need to configure a CNAME DNS entry pointing to storage.googleapis.com.

Please see https://cloud.google.com/storage/docs/xml-api/reference-uris#cname for further instructions.

Temporary / Signed URLs

With the latest adapter versions, you can easily generate a signed URLs for files that are not publicly visible by default.

$disk = Storage::disk('gcs');
$url = $disk->temporaryUrl('folder/my_file.txt', now()->addMinutes(30));
// https://storage.googleapis.com/test-bucket/folder/my_file.txt?GoogleAccessId=test-bucket%40test-gcp.iam.gserviceaccount.com&Expires=1571151576&Signature=tvxN1OS1txkWAUF0cCR3FWK%seRZXtFu42%04%YZACYL2zFQxA%uwdGEmdO1KgsHR3vBF%I9KaEzPbl4b7ic2IWUuo8Jh3IoZFqdTQec3KypjDtt%02DGwm%OO6pWDVV421Yp4z520%o5oMqGBtV8B3XmjW2PH76P3uID2QY%AlFxn23oE9PBoM2wXr8pDXhMPwZNJ0FtckSc26O8PmfVsG7Jvln%CQTU57IFyB7JnNxz5tQpc2hPTHbCGrcxVPEISvdOamW3I%83OsXr5raaYYBPcuumDnAmrK%cyS9%Ky2fL2B2shFO2cz%KRu79DBPqtnP2Zf1mJWBTwxVUCK2jxEEYcXBXtdOszIvlI6%tp2XfVwYxLNFU

Uniform bucket-level access

Google Cloud Storage allows setting permissions at the bucket level i.e. "Uniform bucket-level access".

Initially, the error "Cannot insert legacy ACL for an object when uniform bucket-level access is enabled" is observed.

When uploading files to such buckets ensure the visibility_handler within the configuration file is set as follows:

'visibility_handler' => \League\Flysystem\GoogleCloudStorage\UniformBucketLevelAccessVisibility::class,

Please see https://cloud.google.com/storage/docs/access-control/signed-urls and https://laravel.com/docs/6.x/filesystem for more info.
