- generate-config.sh: add --with-nginx flag handling; when enabled, set NEXT_PUBLIC_API_URL empty to use same-origin /api and /socket.io; add BACKEND_INTERNAL_URL for SSR/internal fetch; adjust lan-tls HTTPS (8443) and TLS generation policy
- deploy.sh: show only valid access URLs when Nginx is enabled (gateway URLs), avoid misleading :3002/:3001 entries
- frontend (env/webrtc): return mutable transports [websocket,polling]; use empty signaling server for same-origin; comments in English
- frontend (next.config): support NEXT_IMAGE_UNOPTIMIZED to turn off image optimization in Docker
- frontend (health): prefer BACKEND_INTERNAL_URL for internal health checks, fallback to public URL/localhost
- docker-compose + Dockerfile(frontend): pass NEXT_IMAGE_UNOPTIMIZED and BACKEND_INTERNAL_URL envs
- generate-config.sh
- Add flags: --no-clean, --reset-ssl, --ssl-mode (letsencrypt|self-signed|provided)
- Stop deleting docker/ssl by default; only wipe on explicit --reset-ssl
- Inject ACME webroot route into HTTP (80) server; create docker/letsencrypt-www
- Default SSL_MODE: full=letsencrypt, private/public=self-signed
- Add enable_https_if_cert_present: append 443 server only when server-cert.pem/server-key.pem exist
- Keep self-signed path generating HTTPS immediately (non-basic)
- docker-compose.yml
- Mount ./docker/letsencrypt-www:/var/www/certbot:ro for Nginx ACME challenges
- deploy.sh
- Add --le-email for Let’s Encrypt account email
- Auto-install certbot once (apt-get) and enable systemd timer if available
- Install deploy hook at /etc/letsencrypt/renewal-hooks/deploy/privydrop-reload.sh to:
- Copy renewed certs into docker/ssl
- Hot-reload Nginx; HUP or restart coturn
- First-time issuance (webroot) for <domain> and turn.<domain> after Nginx:80 is up; copy certs
- Re-run generate-config with --no-clean --ssl-mode letsencrypt to enable 443, then reload Nginx
- Behavior changes
- Full mode prefers Let’s Encrypt by default; HTTPS gets enabled as soon as certs exist
- docker/ssl is no longer wiped by config generation
- Notes
- SNI-based turns:443 is not implemented yet (planned)
- Backward compatible with private/public (self-signed)
- Switch all CLI examples to Docker Compose V2 (docker compose) for consistency.
- Add explicit instruction to grant write permissions to the host logs/ directory (chmod 777 -R logs) to fix coturn/nginx bind-mount logging errors.
- Parameterize TURN UDP port range via TURN_MIN_PORT/TURN_MAX_PORT and set a safer default 49152-49252 to reduce startup/cleanup overhead and port
conflicts.
- Update troubleshooting with coturn log write failure guidance and port conflict hints.
- Clarify that LAN IP is auto-detected in private mode; --local-ip is no longer needed by default but remains as an override for edge cases.
Test steps:
bash docker/scripts/generate-config.sh --mode private [--local-ip 192.168.0.113]
bash ./deploy.sh --mode private
Front-end directly inlines NEXT_PUBLIC_API_URL, directly connecting to the backend.
CORS (production) supports comma-separated multiple origins, with localhost and local network IPs included by default.
