docker-entrypoint-initdb.d/* files ignored on docker-compose first run

Question

I try to setup a Postgresql db in my docker-compose and it worked as expected for a moment. But now, my migration sql scripts aren't runned anymore, even after a fresh new build ( sudo docker-compose build or sudo docker-compose up --build ) and after removing the persistent volume created locally ( sudo rm -rf db-data ).

$ sudo docker-compose up

As you can see, my docker-entrypoint-initdb.d/* files are all being ignored. Notice that my 3 migrations scripts run fine on a local pg instance.

My docker-compose looks lik this:

version: '3.7'

services:
    db:
        image: postgres
        restart: always
        environment:

          - POSTGRES_PASSWORD=***
          - POSTGRES_DB=***
        ports:

        volumes:
