a new anonymous docker volume is created at each "docker compose up"

While testing some changes to the stock docker compose file, and doing a few rounds of docker compose down and ups, I noticed that a bunch of anonymous docker volumes.

Turns out this is the culprit

To prevent this from happening, we need to add a
``` - db-config:/data/configdb ```
line in each of the docker-compose.yaml templates.

I'll create a pull request when I get a chance but wanted to document this here and see if anyone would beat me to it.
