SQL script isn't executed during launching of mysql container - mysql

Question

I'm very new at docker and docker-composer. I'm trying to make a mysql container which will be used by a php-apache container.
I have a SQL script which create a database and insert values.
I want my mysql container to execute this SQL script at his launching, so the app will be able to make queries on it. here's my docker-compose file :
version: "3.7"
services:
mysql:
image: mysql:latest
container_name: mysql
restart: always
volumes:
- db-volume:/var/lib/mysql
- ./bdd.sql:/docker-entrypoint-initdb.d/bdd.sql
environment:
MYSQL_ROOT_PASSWORD: test
MYSQL_DATABASE: webreathe
app:
image: toto:latest
container_name: toto
restart: always
volumes:
- ./:/var/www/webreathe
ports:
- 8080:80
depends_on:
- mysql
volumes:
db-volume:
I launch it with docker-compose up -d
and I want to see if my database was created so I execute inside of the mysql container :
mysql -u root -p test -e "show databases;"
but the result is :
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
| test |
+--------------------+
So I wonder if the bdd.sql file was in the /docker-entrypoint-initdb.d directory
and yes it is : ls docker-entrypoint-initdb.d => bdd.sql
Do you know why it doesn't execute the script ?
