Create and use your filesystems

After successfully configured the adapters, create a filesystem and inject an adapter of your choice.

oneup_flysystem:
    adapter: ~
    filesystems:
        acme:
            adapter: my_adapter
            cache: ~
            alias: ~
            mount: ~
            visibility: ~

This will expose a new service for you to use.

$filesystem = $container->get('oneup_flysystem.acme_filesystem');

The naming scheme follows a simple rule: oneup_flysystem.%s_filesystem whereas %s is the name (config key) of your filesystem.

The $filesystem variable is of the type \League\Flysystem\Filesystem. Please refer to the General Usage section in the official documentation for details.

Alias your filesystem

You can alias your filesystem by providing an alias key.

oneup_flysystem:
    adapter: ~
    filesystems:
        acme:
            adapter: my_adapter
            alias: acme_filesystem

Afterwards, the filesystem service is aliased with the provided value and can be retrieved like this:

$filesystem = $container->get('acme_filesystem');

Inject your filesystem in your services

If you use Dependency Injection instead of the container as service locator, you can inject your filesystems in your services:

services:
    app.my_service:
        class: App\MyService
        arguments:
            - '@oneup_flysystem.acme_filesystem' # Inject the resolved service name, or the alias (see previous section)

Dependency Injection is considered a good practice since you do not need the container, and you can then refer to it in your class like this:

use League\Flysystem\FilesystemInterface;

class MyService
{
    public function __construct(FilesystemInterface $acmeFilesystem)
    {
        $this->filesystem = $acmeFilesystem;
    }
}

💡 Pro tip: when using Symfony 4.2, you can completely omit the service arguments definition in your config files, and instead you can automatically inject your filesystems by providing the exact same type-hint as above, and replace acme with the name of your filesystem. Thanks to the ContainerBuilder::registerAliasForArgument() method!

Use the Mount Manager

If you provided a mount prefix, you can also access the filesystem through the MountManager.

oneup_flysystem:
    adapters:
        myadapter:
            local:
                directory: "%kernel.root_dir%/cache"

    filesystems:
        myfilesystem:
            adapter: myadapter
            mount:   prefix

$filesystem = $container->get('oneup_flysystem.mount_manager')->getFilesystem('prefix');

Details on the usage of the MountManager can be found in the Flysystem documentation.
