Add Laravel storage disk/filesystem on the fly

Question

I keep multiple FTP accounts in a database table and would like each one to be available as a storage disk in Laravel.

Normally, Laravel's disks are defined in config/filesystems.php. But instead of hardcoding my FTP accounts there, I would like to define them on the fly (in a middleware).

Is this possible? How do I accomplish that?

Answer 1

Laravel's FilesystemManager has methods to create most common disks.

<?php
use Illuminate\Filesystem\FilesystemManager;
$fsMgr = new FilesystemManager(app());
// local disk
$localDisk = $fsMgr->createLocalDriver(['root' => "/path/to/root"]);
// FTP disk
$ftpDisk = $fsMgr->createFtpDriver([/* FTP options */]);
// SFTP disk
$sftpDisk = $fsMgr->createSftpDriver([/* SFTP options */]);
// S3 disk
$s3Disk = $fsMgr->createS3Driver([/* S3 options */]);

Apart from that, you can create any filesystem supported by your league/flysystem installation, you only need to wrap it in Illuminate\Filesystem\FilesystemAdapter:

<?php
use League\Flysystem\FilesystemInterface;
// create any Flysystem instance and wrap it in Laravel's adapter
$myDisk = new FilesystemAdapter(/* \League\Flysystem\FilesystemInterface */ $filesystem);

This way you create your disks on-the-fly, without the need to modify the application config, handy if you have lots of connections, for example, to partners' FTP/SFTP servers, GCloud or S3 buckets.

I created a service provider MyDiskServiceProdiver with this method:

public function boot()
{
    MyDisk::all()->each(function(MyDisk $myDisk) {
        $this->app['config']["filesystems.disks.{$myDisk->name}"] = ['driver' => $myDisk->driver] + $myDisk->config;
    });
}

Where the config attribute is of type json in database and holds several driver-specific attributes.

Create a new service provider php artisan make:provider FileSystemServiceProvider

Register the provider in the config/app.php If you open the config/app.php file included with Laravel, you will see a provider's array. register the created service provider there.

In The Boot Method of the created service provider use the below-mentioned code to register the disks Assuming fileSystemsDetails is the model name

public function boot() {
    DomainSettings::all()->each(function(DomainSettings $myDisk) {

        if (!is_null($myDisk->driver_name) && !is_null($myDisk->driver_type)
            && !is_null($myDisk->driver_host) && !is_null($myDisk->driver_username) && !is_null($myDisk->driver_password)) {

            $this->app['config']["filesystems.disks.{$myDisk->driver_name}"] =
                [   'driver' => $myDisk->driver_type,
                    'host' => $myDisk->driver_host,
                    'username' => $myDisk->driver_username,
                    'password' => $myDisk->driver_password,
                    'root' => $myDisk->driver_root,
                ];
        }
    });
}
