Why doesn't Docker-compose volume mount data from container to local machine?

Question

Docker

Hello! Please tell me why this is happening.

I have three official builds - nginx, fpm, postgres. When I assemble containers from them, the volume on postgres completely from scratch creates a local folder with a database from the container, which I didn’t have before, and the rest of the volumes are just empty folders without data.

I want to have maximum control over ngix and php, so I listen to /etc/nginx and /usr/local/etc respectively. But unlike postgres, these folders from containers are created without data and, accordingly, delete nginx and php data in containers.

Answer 1

Probably because volumes forwards the local directory to the container, and not vice versa.
