Introduction

Currently not deployed!

I created a fake IoT API that provides pseudo-real IoT data. It’s available at fakeiotapi.xyz.

This was mostly done for me to learn deployment of a full stack application on AWS so the actual frontend and backend code is simple and probably not following best practices.

Application

The application is created with Go, React, PostgreSQL and nginx, all running as Docker containers on a single EC2 instance. Certificates are created using Let’s Encrypt and Certbot.

Deployment diagram

The application is hosted on a single EC2 instance, so deployment is very basic.

Whole infrastructure (VPC, subnet, DNS stuff, EC2 instance etc.) is created using Terraform.

GitHub CI/CD

I used GitHub Actions to automatically deploy the application on every push to the main branch.

On every push to the main branch, GitHub Actions will:

1. Run integration tests (tests that the GO API is working correctly)

2. Sync the code from repository to EC2 instance (using rsync)

3. Build and deploy the application (using docker-compose)

Conclusion

Some improvements that could be done:

• Deploy using ECS instead of EC2
• Automate certificate creation (and renewal)
