Flysystem adapter for Google Cloud Storage

This package contains a Google Cloud Storage driver for Flysystem v1.

(If you need Google Cloud Storage support on Flysystem v2 or above (or Laravel 9), this package is not for you)

Notice

This package is a fork from superbalist/flysystem-google-cloud-storage. Changes include:

• PHP 8 only
• merged random open PRs from Superbalist's package

Installation

You can install the package via composer:

composer require spatie/flysystem-google-cloud-storage

Authentication

Before you can use the package, you'll need to authenticate with Google. When possible, the credentials will be auto-loaded by the Google Cloud Client.

1. The client will first look at the GOOGLE_APPLICATION_CREDENTIALS env var. You can use putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json'); to set the location of your credentials file.
2. The client will look for the credentials file at the following paths:
   • Windows: %APPDATA%/gcloud/application_default_credentials.json
   • MacOS/Unix: $HOME/.config/gcloud/application_default_credentials.json
3. If running in Google App Engine, Google Compute Engine or GKE, the built-in service account associated with the app, instance or cluster will be used.

Using this in a Kubernetes cluster? Take a look at Workload Identity.

Usage

Here's an example that shows you have you can call the various functions to manipulate files on Google Cloud.

use Google\Cloud\Storage\StorageClient;
use League\Flysystem\Filesystem;
use Spatie\GoogleCloudStorageAdapter\GoogleCloudStorageAdapter;

$storageClient = new StorageClient([
    'projectId' => 'your-project-id',
    // The credentials can manually be specified by passing in a keyFilePath.
    // 'keyFilePath' => '/path/to/service-account.json',
]);

$bucket = $storageClient->bucket('your-bucket-name');

$adapter = new GoogleCloudStorageAdapter($storageClient, $bucket);

$filesystem = new Filesystem($adapter);

$filesystem->write('path/to/file.txt', 'contents');
$filesystem->update('path/to/file.txt', 'new contents');
$contents = $filesystem->read('path/to/file.txt');
$exists = $filesystem->has('path/to/file.txt');
$filesystem->delete('path/to/file.txt');
$filesystem->rename('filename.txt', 'newname.txt');
$filesystem->copy('filename.txt', 'duplicate.txt');
$filesystem->deleteDir('path/to/directory');

See https://flysystem.thephpleague.com/v1/docs/usage/filesystem-api/ for full list of available functionality

Using a custom storage URI

You can configure this adapter to use a custom storage URI. Read more about configuring a custom domain for Google Cloud Storage here.

When using a custom storage URI, the bucket name will not prepended to the file path:

use Google\Cloud\Storage\StorageClient;
use League\Flysystem\Filesystem;
use Spatie\GoogleCloudStorageAdapter\GoogleCloudStorageAdapter;

$storageClient = new StorageClient([
    'projectId' => 'your-project-id',
]);
$bucket = $storageClient->bucket('your-bucket-name');
$adapter = new GoogleCloudStorageAdapter($storageClient, $bucket);

// URI defaults to "https://storage.googleapis.com":
$filesystem = new Filesystem($adapter);
$filesystem->getUrl('path/to/file.txt');
// "https://storage.googleapis.com/your-bucket-name/path/to/file.txt"

// Using custom storage uri:
$adapter->setStorageApiUri('http://example.com');
$filesystem = new Filesystem($adapter);
$filesystem->getUrl('path/to/file.txt');
// "http://example.com/path/to/file.txt"

// You can also prefix the file path if needed:
$adapter->setStorageApiUri('http://example.com');
$adapter->setPathPrefix('extra-folder/another-folder/');
$filesystem = new Filesystem($adapter);
$filesystem->getUrl('path/to/file.txt');
// "http://example.com/extra-folder/another-folder/path/to/file.txt"
