/public/index.php (Local) maps to /application/public/index.php (Container)
The folder /application inside of the container is not accessible via any http methods (Browser, Postman and so on...). This is useful if you use a php framework like Laravel where you only want to expose the public/published parts while the main application works its magic.
So if you want to access your files via Browser they have to be in the public folder.
Excuse my lack of terminology, i'm still learning the correct words ;)
