DevOps & Infrastructure

The application is deployed with focus on security, performance, and scalability. It's running in a server environment isolated within a DMZ network.

Docker & Containers 🐳

The app is managed via docker-compose and consists of five containers:

• MongoDB
• Node.js/Express (custom-built backend container)
• NGINX (serves the frontend statically)
• NGINX Reverse Proxy (handles routing & SSL termination)
• Watchtower (automatically updates running containers)

NGINX Reverse Proxy & SSL

• SSL termination is handled by the NGINX Reverse Proxy, which is the only container exposed to the internet
• This setup allows multiple web apps to run behind a single public IP
• Internal routing is handled via Docker networks
• Certificates are generated and managed automatically via Let’s Encrypt

Network Architecture

• The application runs inside an isolated DMZ
• Only port 443 (HTTPS) is open to the outside world
• Geoblocking is enabled – only Swedish IP addresses are allowed

Continuous Deployment

• CI/CD is prepared – tools like GitHub Actions and Docker Hub builds were explored
• Deployment is currently manual due to time constraints, but groundwork for automation is already in place

There’s a lot I had hoped to polish further, but my focus was on hitting the goals I set for this project – and I did.
