    'aliases' => [
        '@storageUrl' => 'https://cdn.site.com/storage',
    ],
    'components' => [
        'fs' => [
            'class' => diecoding\flysystem\LocalComponent::className(),
            'path' => '@common/cdn',
            'secret' => 'secret'
        ]
    ],
];

Add action to the main controller

class PageController extends Controller
{
    public function actions()
    {
        return [
            'upload' => [
                'class' => UploadAction::className(),
            ],
        ];
    }
}

use lav45\fileUpload\UploadBehavior;
use lav45\fileUpload\UploadInterface;

class Page extends ActiveRecord implements UploadInterface
{
    use UploadTrait;

    public function rules()
    {
        return [
            [['image'], 'string'],
        ];
    }

        return [
            [
                'class' => UploadBehavior::className(),
                'attribute' => 'image',
            ],
        ];
    }

    {
        return '/page/' . $this->id;
    }
}

Need to add a field for uploading files

/**
 * @var Page $model
 */
 
use lav45\fileUpload\widget\FileUpload;

$form = ActiveForm::begin();

echo $form->field($model, 'image')->widget(FileUpload::className());

ActiveForm::end();

<?php /** @var Page $model */ ?>
 
<img src="<?= $model->getAttributeUrl('image') ?>" alt="">
