run command in docker-compose.yml

Question

I have laravel project and must create a docker container for this. I am done doing this but for MySQL I must run some commands

docker-compose exec app php artisan key:generate
docker-compose exec db bash
mysql -u root -p
Login Using password Library!23
GRANT ALL ON laravel.* TO 'root'@'%' IDENTIFIED BY '123';
FLUSH PRIVILEGES;
EXIT;
exit
docker-compose exec app php artisan migrate

In the line 2 app switch the bash and I must exit to run commands but I need to open MySQL bash login and give permission to the user after that run artisan migrate and its my docke-compose.yml

Answer 1

for step 2 - 8 you have to ways like our friends says create bootstrap file with sql commands and run it in your dockerfile or you can create user and pass and grant admin access to user in docker-compose.yml

 db:
    image: mysql:5.7.22
    container_name: Librarydb
    restart: unless-stopped
    tty: true
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: library
      MYSQL_ROOT_PASSWORD: TheRootPassword
      MYSQL_USER: root
      MYSQL_PASSWORD: PasswordForLoginAndUse
      SERVICE_TAGS: dev
      SERVICE_NAME: mysql
    networks:
      - app-network
    volumes:
      - dbdata:/var/lib/mysql

and about generating a key with artisan its not necessary
app think you run it in one system because of docker
and i prefer you to run migration manually
its better

Answer 2

instead of executing the MySQL commands directly (or manually). You can bootstrap MySQL containers with all the needed data and configurations using the following approach.

1- Create a bootstrap file : sql-scripts.sql

GRANT ALL ON laravel.* TO 'root'@'%' IDENTIFIED BY '123';
FLUSH PRIVILEGES;

2- Create a custom MySQL Docker image: mysql.Dockerfile

FROM mysql:8.0.1
COPY ./sql-scripts.sql /docker-entrypoint-initdb.d/

3- build MySQL docker image and use it in your docker-compose file. You need to before the below change on your docker-compose. The bootstrap file will be executed automatically the FIRST TIME you execute docker-compose up . you need to remove the MySQL volume to make this works for your stack docker volume rm dbdata .

db:
    build:
      context: .
      dockerfile: mysql.Dockerfile
