# Reverse proxy template for a REAL deployment (real domain + automatic HTTPS).
# Not needed for local testing against localhost:4650 — this is the step you
# take once you're actually putting this in front of a public domain.
#
# Our recommendations where to deploy this streamable online course and training platform
# is only either Cloudflare (with Tunnels For free) or other cloud VPS platforms (DigitalOcean,Google et.al)
#
# Usage:
#   1. Point 3 DNS records at this machine: your app domain, your api
#      subdomain, and your cdn subdomain (matching FRONTEND_URL / APP_URL /
#      S3_PUBLIC_URL in apps/api/.env and VITE_APP_URL / VITE_API_URL in
#      apps/web/.env). Either edit the three domains below directly, or set
#      the FRONTEND_DOMAIN / API_DOMAIN / CDN_DOMAIN env vars before running
#      Caddy and leave the placeholders as-is.
#   2. Install Caddy (https://caddyserver.com/docs/install) directly on this
#      host — it is NOT part of docker-compose.yml, so it binds host ports
#      80/443 directly and reverse-proxies to the containers' published
#      ports below.
#   3. Copy this file to /etc/caddy/Caddyfile (or wherever your install
#      expects it).
#   4. sudo systemctl reload caddy   (or: caddy run --config Caddyfile)
#
# Caddy issues and renews Let's Encrypt certificates automatically the first
# time each domain is requested — no manual cert steps needed.
