Microsoft Azure Blob Storage integration for Laravel's Storage API

License: MIT License

Languages: PHP

DEPRECATION NOTICE

This package is dependent on Flysystem's Azure Blob Storage integration. The creator of that has announced that because Microsoft are dropping support for their PHP storage client, he will also be dropping Azure support from Flysystem in 2024.

As a result, there is no viable path for me to continue to maintain this package past that point. It will therefore be deprecated at the same time.

If you're currently using this package on a project, I suggest you begin considering alternatives to Azure that are officially supported by Laravel, such as Amazon S3.

CircleCI

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 3. 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 matthewbdaly/laravel-azure-storage

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

        'azure' => [ // NB This need not be set to "azure", because it's just the name of the connection - feel free to call it what you want, or even set up multiple blobs with different names
            'driver'    => 'azure', // As this is the name of the driver, this MUST be set to "azure"
            'name'      => env('AZURE_STORAGE_NAME'),
            'key'       => env('AZURE_STORAGE_KEY'),
            'container' => env('AZURE_STORAGE_CONTAINER'),
            'url'       => env('AZURE_STORAGE_URL'),
            'prefix'    => null,
            'connection_string' => env('AZURE_STORAGE_CONNECTION_STRING') // optional, will override default endpoint builder 
        ],

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,
            'connection_string' => 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'),
        ],

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
            ]
        ],

Unsupported features

As this package uses the Flysystem Azure integration, it shares the following limitations with that:

  • Visibility setting or retrieving is not supported.
  • Mimetypes are always resolved, where others do not.
  • Directory creation is not supported in any way.

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.

Can you add support for storage backend X?

No. This is exclusively for Azure Blob storage, and I am categorically not interested in expanding the scope of it to support other backends.

As long as Flysystem supports it, you can roll your own Laravel filesystem driver easily as described at https://laravel.com/docs/9.x/filesystem#custom-filesystems if you need to - this is the method I used to build this package.
