How to call a local ressource from a container?

Hello,
I builded : Apache, Php7.3, and Postgresql images with ‘docker-compose.yml’.

Everything works good, but when I make a call of a local photo, I get a warning message and the photo doesn’t appear.

This is the error message :
Warning: getimagesize(https://localhost:80/tofs.domain.com/photo.php?id=1): failed to open stream: Cannot assign requested address.

I get the same message when I use ‘file_get_contents’ function with ‘localhost’.

Note : calling an external ressource works for theses functions.

So, what must I do to resolve this problem ?

Thanks.
