Problem with executing laravel migrations on Elastic Beanstalk

I deployed my laravel application using Elastic beanstalk, and I need to execute php artisan:migrate command on the remote database. Based on Maximilian's tutorial I created init.config file inside .ebextensions with contents:

container_commands:
    01initdb:
        command: "php artisan migrate"

The status of the deployment is Healthy, but it didn't create any table! any clues, please?
