Hello my fellow Dockerteers,
I am new to Docker and currently trying to figure out the best approach to building a MySQL container to be used with a volume for persistent data.
From my research and studies I seem to be getting different advice from different sources on how to best do this.
It seems I can achieve this by both a Dockerfile or docker-compose.yml file.
So my understanding mount volumes can be done via these methods:
- For Dockerfile:
VOLUME /var/lib/mysql
- For docker-compose.yml file:
volumes:
./my-vol:/var/lib/mysql
So which to use, and to me it seems they both can do the similar things so why do both exist?
Although it seems with Dockerfile, it is a bit more limited as you cannot seem to specify the source drive, only the target drive?
So please recommend me the best practice/recommended method?
