Inception — Docker Infrastructure

42 Urduliz — Common Core project

A complete containerized infrastructure built from scratch using Docker Compose. Three custom Docker images orchestrated together: NGINX (reverse proxy with TLS), WordPress (with php-fpm), and MariaDB.

---

Features

• NGINX with TLSv1.2/1.3 — only HTTPS entry point
• WordPress + php-fpm (no nginx in the same container)
• MariaDB — dedicated database container
• Persistent volumes for database and WordPress files
• Custom Docker network (no --link, no network: host)
• All images built from scratch (Debian/Alpine based, no DockerHub pre-built images)

Build & Run

make

Requires Docker and Docker Compose. Configure your credentials in srcs/.env (see .env.example).
