Hi,

I’m getting the following error when trying to run `sudo docker-compose up -d`

`ERROR: Invalid interpolation format for "environment" option in service "rasa-x": "${DB_USER:-admin}"`

I followed the steps mentioned in [Deploy to a Server](https://rasa.com/docs/rasa-x/deploy/) while trying to deploy it to a Amazon lightsail instance.

**Environment:**

- OS: Ubuntu 16.04.6 LTS
- Python: 3.6.8
- Docker: 18.09.7, build 2d0083d
- Docker-compose: 1.24.1, build 4667896b
