Reverse Proxy with Spring Boot & Caddy | Beginner Friendly
Learn how to use Caddy server with a Spring Boot application for modern, secure, and production-ready deployments — all using Docker Compose! Caddy is a powerful, lightweight web server with automatic HTTPS and reverse proxy capabilities that make it the perfect companion for Spring Boot microservices.
🔍 What is Caddy?
Caddy is a next-gen web server that comes with built-in HTTPS, zero-config TLS, automatic certificate renewal via Let's Encrypt, and a simple configuration file. Unlike Nginx or Apache, Caddy manages certificates automatically — no Certbot or cron jobs needed!
💡 Why Use Caddy with Spring Boot?
Spring Boot apps usually run on port 8080, which is not secure or accessible publicly by default. With Caddy, you can:
Easily expose Spring Boot apps via HTTPS
Handle reverse proxying with a few lines of config
Add load balancing with built-in support
Use Docker to streamline deployment
