[docker] Question about volumes

I run many Docker containers on my server. The way I like to set up my containers is that for their config dirs, I generally put them in my ~/docker dir. Let me give you an example.

The default docker-compose syntax for mariadb is:

- db:/var/lib/mysql

Can I change that to:
- /home/mike/docker/db:/var/lib/mysql
?? Is there any reason to change it?

you can do both. As you wish.
