Microsoft Azure Blob Storage integration for Laravel's Storage API.

This is a custom driver for Laravel's File Storage API, which is itself built on top of Flysystem. It uses Flysystem's own Azure blob storage adapter, and so can't easily add any more functionality than that has - indeed, adding that would be out of scope for the project.

Installation

Install the package using composer:

composer require deva7mad/laravel-azure-storage

On Laravel versions before 5.5 you also need to add the service provider to config/app.php manually:

    Deva7mad\LaravelAzureStorage\AzureStorageServiceProvider::class,

Then add this to the disks section of config/filesystems.php:

        'azure' => [
            'driver'    => 'azure',
            'name'      => env('AZURE_STORAGE_NAME'),
            'key'       => env('AZURE_STORAGE_KEY'),
            'container' => env('AZURE_STORAGE_CONTAINER'),
            'url'       => env('AZURE_STORAGE_URL'),
            'prefix'    => null,
        ],

Finally, add the fields AZURE_STORAGE_NAME, AZURE_STORAGE_KEY, AZURE_STORAGE_CONTAINER and AZURE_STORAGE_URL to your .env file with the appropriate credentials. The AZURE_STORAGE_URL field is optional, this allows you to set a custom URL to be returned from Storage::url(), if using the $root container the URL will be returned without the container path. A prefix can be optionally used. If it's not set, the container root is used. Then you can set the azure driver as either your default or cloud driver and use it to fetch and retrieve files as usual.

For details on how to use this driver, refer to the Laravel documentation on the file storage API.

Custom endpoints

The package supports using a custom endpoint, as in this example:

        'azure' => [
            'driver'    => 'azure',
            'name'      => env('AZURE_STORAGE_NAME'),
            'key'       => env('AZURE_STORAGE_KEY'),
            'container' => env('AZURE_STORAGE_CONTAINER'),
            'url'       => env('AZURE_STORAGE_URL'),
            'prefix'    => null,
            'endpoint'  => env('AZURE_STORAGE_ENDPOINT'),
        ],

Then you can specify a suitable value for AZURE_STORAGE_ENDPOINT in your .env file as normal.

SAS token authentication

With SAS token authentication the endpoint is required. The value has the following format: https://[accountName].blob.core.windows.net

        'azure' => [
            'driver'    => 'azure',
            'sasToken'  => env('AZURE_STORAGE_SAS_TOKEN'),
            'container' => env('AZURE_STORAGE_CONTAINER'),
            'url'       => env('AZURE_STORAGE_URL'),
            'prefix'    => null,
            'endpoint'  => env('AZURE_STORAGE_ENDPOINT'),
        ],

Caching

The package supports disk based caching as described in the Laravel documentation. This feature requires adding the package league/flysystem-cached-adapter:

composer require league/flysystem-cached-adapter:^1.1

To enable caching for the azure disk, add a cache directive to the disk's configuration options.

        'azure' => [
            'driver'    => 'azure',
            // Other Disk Options...
            'cache'     => [
                'store' => 'memcached',
                'expire' => 600,
                'prefix' => 'filecache',
            ]
        ],

Retries

The Azure Storage SDK ships a middleware to retry failed requests. To enable the retry middewalre, add a retry directive to the disk's configuration options.

        'azure' => [
            'driver'    => 'azure',
            // Other Disk Options...
            'retry'     => [
                'tries' => 3,                   // number of retries, default: 3
                'interval' => 500,              // wait interval in ms, default: 1000ms
                'increase' => 'exponential'     // how to increase the wait interval, options: linear, exponential, default: linear
            ]
        ],

Support policy

This package is supported on the current Laravel LTS version, and any later versions. If you are using an older Laravel version, it may work, but I offer no guarantees, nor will I accept pull requests to add this support.

By extension, as the current Laravel LTS version required PHP 7.0 or greater, I don't test it against PHP < 7, nor will I accept any pull requests to add this support.
