Docker Compose mysql import .sql

Question

I'm having trouble importing an .sql dump file with docker-compose. I've followed the docs, which apparently will load the .sql file from docker-entrypoint-initdb.d. However, when I run docker-compose up, the sql file is not copied over to the container.

I've tried stopping the containers with -vf flag, but that didn't work either. Am I doing something wrong in my .yml script?

I have dump.sql in the directory database/db-dump/ in the root where my compose file is.

frontend:
  image: myimage
  ports:
   - "80:80"
  links:
   - mysql
mysql:
  image: mysql
  ports:
   - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: rootpass
    MYSQL_USER: dbuser
    MYSQL_PASSWORD: userpass
    MYSQL_DATABASE: myimage_db
  volumes:
   - ./database/db-dump:/docker-entrypoint-initdb.d

Answer 1

This worked for me,

version: '3.1'

services:

  db:
    image: mysql
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    volumes:
      - ./mysql-dump:/docker-entrypoint-initdb.d
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: ecommerce

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

mysql-dump must be a directory. All the .sql's in the directory will be imported.
