I would like to setup some MySql tables upon Docker startup, however it doesn't look like it works. Here's my DockerfileMySql: 
FROM mysql
ENV MYSQL_DATABASE football_simulation
COPY initial.sql /docker-entrypoint-initdb.d/
And this is my docker-compose.yml:
version: '3'
services:
        mysql-development:
                image: mysql:5.7.30
                environment:
                        MYSQL_ROOT_PASSWORD: password
                        MYSQL_DATABASE: football_simulation
                ports:
                - "3308:3306"
                volumes:
                - ./initial.sql /docker-entrypoint-initdb.d/
        admin:
                image: adminer
                ports:
                - "8080:8080"
Finally my initial.sql: 
CREATE TABLE IF NOT EXISTS tournament
(    id     INTEGER      NOT NULL PRIMARY KEY,
    `name` VARCHAR(255) NOT NULL
);
I run docker build . and docker-compose up and go over to localhost:8080, the UI is up with football_simulation database setup, but with no tables inside. What am I doing wrong?
