Use of docker volume for data makes it hard to customize

[KoenDG]

I mistakenly commented on the source repo: grocy/grocy#486 (comment)

And my issue is this: changing the currency of groccy can only be done by editing the config.php file.

Using this setup, from this repository here, I seemingly have no option but to go into the container with docker exec, and modify the file with vi.

Unless there's a way to easily browse the content of docker volumes that I don't know about?

Configuration options should be available before starting software or a container that runs the software.

What can be done to move configuration out of the docker volume?

You can change currency by setting environment variables. The default docker-compose provided uses a .env file for this, grocy.env

But I am using environment variables just fine, eg:

  backend:
    image: "grocy/backend:v4.0.3"
    environment:
    - GROCY_CURRENCY=CAD

Yeah I tried grocy.env and it didn't work.

Deleted my image and volumes and everything, started a new instance... still USD.

And yeah, I didn't consider setting an environment variable directly.
