Nginx Reverse Proxy: Managing Multiple Docker Services on a Single VPS

Short summary

The author demonstrates a production-grade setup using Nginx as a reverse proxy in Docker containers to serve 13+ web applications on a single VPS. Docker networking isolates services with name-based routing, while Let's Encrypt and Certbot automate SSL certificate renewal without downtime. This approach centralizes security management, enables caching integration, and simplifies infrastructure operations.

• •Nginx reverse proxy in Docker solves port conflicts by routing requests based on domain names
• •Docker bridge networking allows containers to communicate by service name, decoupling from IP addresses
• •Let's Encrypt + Certbot automation renews SSL certificates with Nginx config reload ensuring zero downtime
