[Copilot]

Replaces the entire Nginx setup with Caddy v2 across all environments. Caddy eliminates the need for manual SSL certificate management — it obtains and renews Let's Encrypt certs automatically.

Config files

Three Caddyfiles replace the two nginx configs:

File	Purpose
docker/caddy/Caddyfile	Dev — HTTP only, port 80
docker/caddy/Caddyfile.prod	Production — auto HTTPS via ACME
docker/caddy/Caddyfile.prod.http	Production behind TLS-terminating load balancer

# Production: automatic HTTPS, security headers, static file caching
rap8.nl, www.rap8.nl {
    encode gzip
    header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
    handle /static/* { root * /app; file_server; header Cache-Control "public, max-age=2592000, immutable" }
    handle { reverse_proxy web:8000 { header_up Host {host}; header_up X-Real-IP {remote_host} } }
}

Docker Compose

• All three compose files (dev, prod, prod.http) updated: nginx:stable → caddy:2
• docker-compose.prod.yml gains caddy_data and caddy_config named volumes for persistent cert storage, and exposes 443/udp for HTTP/3
• SSL cert volume mounts (/etc/letsencrypt/...) removed — no longer needed

Removed

• docker/nginx/nginx.conf and docker/nginx/nginx.prod.conf deleted
• setup_ssl function removed from scripts/deploy.sh (certbot setup, cron renewal hook)
• scripts/generate_secrets.sh no longer creates an SSL directory

Docs & scripts updated

DEPLOYMENT.md, CI_CD_SETUP.md, project_description.md, roadmap.md, README.md, and error-pages/README.md all updated to reflect Caddy.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 127.0.0.11
  • Triggering command: REDACTED, pid is -1 (packet block)
• 172.19.0.1
  • Triggering command: REDACTED, pid is -1 (packet block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

replace the nginx setup by Caddy. make sure to replace all. test to make sure it works
