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,

Answer 1

After many attempts with the volumes setting i found a workaround

I created another image based on mysql with the following in the Dockerfile

FROM mysql:5.6

ADD dump.sql /docker-entrypoint-initdb.d

Then removed the volumes from compose and ran the new image

frontend:
  image: myimage
  ports:
   - "80:80"
  links:
   - mysql
mysql:
  image: mymysql
  ports:
   - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: rootpass
    MYSQL_USER: dbuser
    MYSQL_PASSWORD: userpass
    MYSQL_DATABASE: myimage_db

This way the dump is always copied over and run on startup
