Multiple sites on a single server with docker - docker

Question

I'm looking to stand up a number of Django websites via docker-compose, on a single server, and I'm having some trouble getting a starting config together. Can anyone point out obvious issues with the below?
the main root site container (website.com):
docker-compose:
version: '3.7'
services:
web:
build:
context: .
dockerfile: Dockerfile.prod
env_file: prod.env
environment:

- DJANGO_SECURE_PROXY_SSL_HEADER_CHECK=True
- VIRTUAL_HOST=website.com
- VIRTUAL_PORT=8000
- LETSENCRYPT_HOST=website.com
command: bash -c "
python manage.py migrate --noinput &&
python manage.py collectstatic --noinput &&
gunicorn config.wsgi:application --bind 0.0.0.0:8000
