These are all the configuration options you can set via environment variables.

Append any of the following keys to your `.env` file, and run `docker-compose up -d` to apply them.

The double-underscores are intentional, as all these settings are translated to yaml internally, a double-underscore indicates the next level.

All of these variables can be set to values, but you can also use a URI-like format to load values from other places:

- `env://<name>` Loads the value from the environment variable `<name>`. Fallback can be optionally set like `env://<name>?<default>`
- `file://<name>` Loads the value from the file `<name>`. Fallback can be optionally set like `file://<name>?<default>`
