Easy option to have bind-mounts

[hertell]

Hi,

I use only bind mounts in all of my docker setups, and it's always a hazzle to keep the docker-compose files up2date because of me changing the volume configs. I do this basically because i'm afraid of accidentally deleting important volumes.. :-D

What i do is i add this optional variable to all volume configs that does not break anything if it's not used

volumes:
  - "${MOUNTPATH:+${MOUNTPATH}/}mongodb_data:/data/db"
  - "${MOUNTPATH:+${MOUNTPATH}/}mongodb_config:/data/configdb"

Maybe this could be something to add to the docker-compose.yaml file?

The Compose files in this repository are provided for testing and evaluation use cases. We don't recommend using them for long-term production setups.

To keep the files simple, I would like to avoid adding more options to the files.
