How to run a *.sh file on Postgres Docker-Compose startup - postgresql

Question

I am trying to create a new DB + User on Postgres when starting a new Docker-Compose Postgres image. For some reason, the init-user-db.sh file is not being copied inside docker-entrypoint-initdb.d folder on the container.
Any idea why?
Thanks
docker-compose.yml:
version: '3'
services:
db:
image: postgres:11
volumes:
- ./db/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
ports:
- '5432:5432'
init-user-db.sh:
#!/bin/bash
set -e
psql -v ON_ERROR_STOP=1 -U "$POSTGRES_USER" <<-EOSQL
CREATE USER bh_ideas_user;
CREATE DATABASE bh_ideas ENCODING UTF8;
GRANT ALL PRIVILEGES ON DATABASE bh_ideas TO bh_ideas_user;
ALTER USER bh_ideas_user WITH PASSWORD 'password123';
ALTER USER bh_ideas_user WITH SUPERUSER;
EOSQL
This is the output I receive:
$ docker-compose up && exit 0

From the docker inspect, the binding is properly done:
"Binds": ["/host_mnt/d/Projects/ideas-api/db/initdb.d:/docker-entrypoint-initdb.d:rw"],
