docker-fullstack-lab

Dockerized full-stack apps across 10+ frameworks (React, Angular, Next.js, Django, FastAPI, Spring Boot, Laravel & more) — a hands-on lab for DevOps engineers to practice containerization patterns.

---

What's Inside

Each project is a self-contained full-stack application with its own Dockerfile, docker-compose.yml, and .env.example. Every stack follows the same layered architecture and exposes a GET /health endpoint for container health checks.

Dockerfile Teaching Examples

Two focused, frontend-only React (Vite) apps for learning how to write Dockerfiles. They are self-contained (no backend, database, or API keys), so they build and run anywhere — ideal for a hands-on class.

Project	Dockerfile style	Runs	Image size	Open at
react-dev-singlestage	Single-stage, development mode	Vite dev server + HMR	~450 MB	http://localhost:5173
react-nginx-multistage	Multi-stage, production	nginx serving static build	~74 MB	http://localhost:8080

Read them side by side to understand why production frontends use multi-stage builds — the multi-stage image is ~6× smaller because Node.js and node_modules are discarded after the build stage. Each folder's README.md walks through its Dockerfile line by line.

Getting Started

Every project follows the same workflow:

cd <project-name>
cp .env.example .env
docker compose up --build

Then hit the health endpoint to confirm everything is running:

curl http://localhost:<port>/health

Each project has its own README.md with the exact port, available API endpoints, and stack-specific notes.

What You'll Practice

• Writing multi-stage Dockerfiles for different runtimes (Node.js, Python, Java, PHP)
• Composing multi-service applications with docker-compose.yml
• Networking containers (frontend → backend → database)
• Using environment variables for configuration
• Adding health checks to Docker services
• Serving frontends via nginx as a reverse proxy
