title: Docker Compose mysql import .sql
body: <p>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 <code>docker-compose up</code>, the sql file is not copied over to the container.</p>
  
  <p>I've tried stopping the containers with <code>-vf</code> flag, but that didn't work either. Am I doing something wrong in my .yml script?</p>
  
  <p>I have dump.sql in the directory database/db-dump/ in the root where my compose file is.</p>
