MySQL image ignores volume configuration of docker-compose.yml
Using the official MySQL Docker image, I don't understand how to mount the data directory to a specifc point on the host. The Dockerfile of the image sets
VOLUME /var/lib/mysql
so database data should be stored "somewhere" on the host. I want to be more specific in my docker-compose file, so I tried the following:
mysql:
image: mysql:5.7
environment:
- MYSQL_ROOT_PASSWORD=password
- MYSQL_DATABASE=mydb
volumes:
- ./database/mysql:/var/lib/mysql
Starting with docker-compose up everything works fine, but the ./database/mysql directory on the host stays empty, whereas /var/lib/mysql in the container contains data. Is there a problem in my configuration? Or do I misunderstand how to use volumes?
