training-software/docker-compose.prod.yml

version: "3.9"

# Production deployment with nginx as the public-facing web server.
# nginx terminates HTTP on port 80, serves static files and the frontend SPA
# directly, and proxies all backend routes to gunicorn.
#
# Quick start:
#   cp .env.example .env.prod   # fill in all values
#   docker compose -f docker-compose.prod.yml up -d --build
#   docker compose -f docker-compose.prod.yml exec web python manage.py migrate
#   docker compose -f docker-compose.prod.yml exec web python manage.py createsuperuser
#
# For HTTPS: terminate TLS at nginx (add ssl_certificate / ssl_certificate_key
# directives to nginx/nginx.conf and map port 443) or put a reverse proxy such
# as Traefik in front and remove the port 80 mapping here.
