Question

I\'m trying to host on docker an application which uses MySQL db. I\'m using docker compose. my yml file looks like this:

version: \'2\'
volumes:
  data_sql:             


        

Answer 1

Simply just put your .sql file (dbcreation.sql) in a folder (ie. /mysql_init) and add the folder as a volume like this:

volumes:
  - /mysql_init:/docker-entrypoint-initdb.d

The MySQL image will execute all .sql, .sh and .sql.gz files in /docker-entrypoint-initdb.d on startup.

Answer 2

1) Create dump file dbcreation.sql

2) Create import.sh file:

#!/usr/bin/env bash
mysql -u root -p$MYSQL_ROOT_PASSWORD < /tmp/dbcreation.sql

3) Create docker-compose.yaml

database:
  image: mysql
  container_name: database.dev
  command: mysqld --user=root --verbose
  volumes:
    - ./dbcreation.sql:/tmp/dbcreation.sql
    - ./import.sh:/tmp/import.sh
  ports:
    - "3306:3306"
  environment:
    MYSQL_DATABASE: "test"
    MYSQL_USER: "test"
    MYSQL_PASSWORD: "test"
    MYSQL_ROOT_PASSWORD: "root"
    MYSQL_ALLOW_EMPTY_PASSWORD: "yes"

"- ./dbcreation.sql:/tmp/dbcreation.sql" - "- local_path:path_inside_container"

4) Run

docker-compose up
docker exec database.dev bash /tmp/import.sh
