Problems with the php artisan command using Laradock

Whenever I use Laravel's artisan command in my laradock workspace to create a controller, model or any other file I can not save or delete this generated file, the system (Linux Mint) asks me to place my user password. I have tried to change the permission of the folder of my project by the workspace and by the system itself, but whenever I execute the artisan command this permission changes and the problem persists.
