Set default values in docker-compose.yml

[Taronyuu]

Issue description

When running docker compose up on a clean pull the database container throws an error with missing env variables.

If this is something you would like I can create a PR with sane defaults :)

Environment

local / development

Steps to reproduce the issue

1. git clone this repo
2. run docker compose up

What is expected?

Sane defaults so the container is able to startup.

In your docker-compose did you specify the env_file?

Works perfect for me if i add the line

env_file:
      - .env
