Nginx Proxy Manager

What it is

Nginx Proxy Manager provides a simple web-based interface to configure Nginx reverse proxy hosts with SSL certificates.

Why I use it

To easily manage reverse proxies for self-hosted apps with Let’s Encrypt integration and minimal manual Nginx config.

How it integrates

• Runs on Synology’s external synobridge network so it can reach other containers.
• Stores persistent config in /data and certificates in /etc/letsencrypt.
• Web UI exposed on ${ADMIN_PORT} (default 81).

Key config

• PUID/PGID → match host user/group IDs for file permissions.
• Ports mapped via .env so you can avoid conflicts with other services.
• Supports custom DB backends (MySQL/MariaDB) if needed, defaults to SQLite.

Security

• Expose ports only as needed; run behind Cloudflare Tunnel if possible.
• Secure the admin interface with a strong password.
• Back up /data and /etc/letsencrypt volumes regularly.

Quick start

1. Copy .env.example → .env and set values (UID/GID, ports, paths).
2. Ensure external Docker network synobridge exists:

   docker network create synobridge
   

3. Launch:

   docker compose up -d
