Docker 在 mysql 容器上导入 sql 脚本

Question

How can this docker script be modified to allow a sql file to be imported into the mysql container? I need to modify the database on the mysql container.

version: '3'
services:
  devbox:
    build:
      context: ./
      dockerfile: DevBox.DockerFile
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - .:/var/gen4
      - ./offers:/var/www/vhosts/offers
  devmysql:
    image: mysql:5.7
    platform: linux/x86_64
    environment:
      MYSQL_ROOT_PASSWORD: mypwd
      MYSQL_DATABASE: offers
    ports:
      - "3306:3306"
    restart: always

Answer 1

The official MySQL images support creating a volume called /docker-entrypoint-initdb.d/

So in your devmysql section of your compose file do something like this

volumes:
    - ./data:/docker-entrypoint-initdb.d/:ro

In this case, you'd want to have a data/ folder in the root of your project (wherever compose is being run from) and in that data/ folder you can put a SQL file with whatever commands you want. They'll be run.

If you're not running the official images, you might be able to create your own image that manually does something similar.
