Introduction

This project implements John Conway's Game of Life as a Django web application, deployed on AWS ECS for scalability and reliability. This demonstrates how container orchestration can modernize classic simulations.

Prerequisites

• AWS Account with appropriate permissions.
• AWS CLI configured.
• Docker installed locally.
• Git repository cloned: git clone https://github.com/UkemeSkywalker/game_of_life

Project Setup

After cloning, navigate to the project directory (cd game_of_life).

Project Structure: The project's structure is as follows:

<code>game-of-life/
├── Dockerfile
├── buildspec.yml
├── requirements.txt
├── manage.py
├── game_of_life/  (Django app)
└── ecs/         (ECS deployment files)</code>

AWS Infrastructure Deployment

1. ECR Repository Creation: Create an ECR repository named game-of-life with image scanning enabled:

aws ecr create-repository --repository-name game-of-life --image-scanning-configuration scanOnPush=true

2. Environment Variable Export: Export necessary environment variables:

export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
export AWS_REGION=us-east-1
export ECR_REPOSITORY_URI=$AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/game-of-life

Test the ECR login:

aws ecr get-login-password --region $AWS_REGION | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com

3. IAM Role Configuration: Create an IAM role named ecsTaskExecutionRole with the AmazonECSTaskExecutionRolePolicy attached.

4. ECS Cluster Creation: Create an ECS cluster named game-of-life using Fargate:

<code>game-of-life/
├── Dockerfile
├── buildspec.yml
├── requirements.txt
├── manage.py
├── game_of_life/  (Django app)
└── ecs/         (ECS deployment files)</code>

Docker Image Build and Push

5. Build the Docker Image: Build the Docker image:

aws ecr create-repository --repository-name game-of-life --image-scanning-configuration scanOnPush=true

6. Tag and Push the Image: Tag and push the image to ECR:

export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
export AWS_REGION=us-east-1
export ECR_REPOSITORY_URI=$AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/game-of-life

Task Definition Creation

7. Update the Task Definition File: Navigate to ecs/ and update task-definition.json with the exported environment variables using sed.

8. Register the Task Definition: Register the task definition:

aws ecr get-login-password --region $AWS_REGION | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com

Game Service Deployment

9. Service Details and Load Balancing: In the AWS ECS console, create a new service named game-of-life-svc, selecting the newly registered task definition and enabling load balancing with an Application Load Balancer.

Accessing the Deployed Game

10. Accessing the Load Balancer Endpoint: Once deployed, obtain the load balancer DNS name from the service details and access the application in your browser.

Conclusion

This deployment successfully demonstrates modernizing a classic application using containerization and cloud infrastructure. The use of Django and AWS ECS provides a scalable and reliable platform for the Game of Life.
