Postgres and redis volumes should be localised to app

[deanfields]

in the docker-compose file volumes are set like this:

- 'postgres:/var/lib/postgresql/data'

But I think they should be set like this:

- './postgres:/var/lib/postgresql/data'

This localizes the folder to the project itself, and it should be ignored in the git file

I think it's best to use named volumes for these. Typically these aren't files you would interact with on a regular basis, so by using named volumes, you just let Docker manage them without worrying about where they live on your file system.

The volumes will be automatically name spaced by the project's name. You can verify that by running docker volume ls.
