Docker-Compose persistent data MySQL

Question

version: \'2\'
services:

Answer 1

You have to create a separate volume for mysql data.

So it will look like this:

volumes_from:
  - data
volumes:
  - ./mysql-data:/var/lib/mysql

And no, /var/lib/mysql is a path inside your mysql container and has nothing to do with a path on your host machine. Your host machine may even have no mysql at all. So the goal is to persist an internal folder from a mysql container.
