### Expected Behavior

- localstack can consume the path I pass `--file`

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

    docker compose up -d
    localstack config validate --file ./compose.yaml


### Environment

```markdown
OS: Ubuntu 20.04
    LocalStack: latest
```


### Anything else?

- you can reproduce [on this branch](https://github.com/noahehall/localstack/tree/rds) if it still exists
  - else switch to the develop branch
