Ec2 on SQP Dev

First Real Cloud Deployment

First Real Cloud Deployment

Today I deployed my first real full-stack application to AWS EC2.

The project is a hospital staff allocation system built with:

React + Vite frontend
Express backend
PostgreSQL database
Docker containers
Docker Compose orchestration

What I Learned

The most important thing was understanding how the different layers connect together.

Final architecture:

Browser
   ↓ HTTPS
DuckDNS
   ↓
Caddy reverse proxy
   ↓
Docker app container
   ↓
PostgreSQL container

Deployment Workflow

The workflow looked like this:

Docker Basics — Building and Deploying to EC2

Fri, 08 May 2026 00:00:00 +0000

Docker packages an application and everything it needs into a container. Same image, identical behaviour on any machine. This post covers building a custom nginx image and deploying it to AWS EC2.

Podman on Fedora

Docker doesn’t run inside a Toolbox container — kernel module restrictions. Podman is Docker-compatible and works natively on Fedora:

echo 'alias docker=podman' >> ~/.bashrc
source ~/.bashrc

Same commands, no workarounds needed from this point.

Building a Custom Image

docker-nginx/
├── Dockerfile
└── index.html

FROM docker.io/library/nginx:latest
COPY index.html /usr/share/nginx/html/
EXPOSE 80

docker build -t my-nginx:v1.0 .
docker run -d -p 8080:80 --name my-nginx my-nginx:v1.0

Open http://localhost:8080 — custom HTML served via nginx inside a container.

First Terraform Deployment on AWS

Tue, 05 May 2026 00:00:00 +0000

With the environment set up, I wrote my first real Terraform code — a complete VPC with a public subnet, security group, and an EC2 instance running nginx.

What I Built

VPC (10.0.0.0/16)
Public subnet with Internet Gateway
Security group (SSH + HTTP)
EC2 instance (Ubuntu 24.04)
SSH key pair
