Deploying a Dockerized Browser Game with Elastic Beanstalk

---

Introduction
I built a simple, colorful browser game using HTML/CSS/JavaScript, containerized it with Docker, and deployed it using AWS Elastic Beanstalk — a service that simplifies deployment for containerized applications.

This post covers the full process — from writing the game to seeing it live on a public URL.

Step 1: Building the Game
I created a browser game called Color Click. The goal is simple: click as many randomly appearing colorful dots as you can. It’s fast, fun, and great for beginners in frontend or game logic.

Technologies used:

• HTML, CSS, JavaScript (Frontend)

• Nginx (as the static file server)

• Docker (to containerize the app)

---

Step 2: Version Control with GitHub
I initialized a Git repo, committed all files (Dockerfile, HTML, CSS, JS), and pushed the code to GitHub.

Step 3: Deploy to AWS Elastic Beanstalk
Elastic Beanstalk allows you to run Docker containers easily without managing infrastructure manually. Here’s what I did:

• Zipped the project files (including Dockerfile)

• Created a new Elastic Beanstalk app via the AWS Console

• Chose the Docker platform

• Set up:

1. Service role

2. EC2 instance profile

3. Key pair (for SSH)

4. Public IP assignment

5. Default VPC with public subnet

Step 4: Access the Game via the Web
After deployment, Elastic Beanstalk assigned a public domain. I simply opened the URL and saw the game running — served via Nginx inside my Docker container on an EC2 instance.
