+Hey there! 👋 I wanted to learn Terraform and how to create infrastructure with Terraform in AWS, then deploy a Laravel app with different services like Redis, RDS, and Nginx. This project is the result of that learning adventure!
+
+I developed this simple blog system following clean code architecture principles. To improve the search functionality, I integrated Elasticsearch, and I'm using Redis for queuing background jobs.
+
+This is my Terraform module to create AWS infrastructure from scratch - it's been quite a journey! 🚀
+
+## 🎯 What I Built
+
+I created a production-ready Laravel blog application that runs on AWS with:
+
+- **Laravel 10** - My choice for the backend framework
+- **AWS ECS Fargate** - Because I wanted to learn containerized deployments
+- **RDS MySQL** - Managed database (no more server maintenance headaches!)
+- **ElastiCache Redis** - For caching and my background job queues
+- **Elasticsearch** - This was tricky but so worth it for advanced search
+- **S3** - File storage made simple
+- **Application Load Balancer** - High availability was important to me
+- **ECR** - Container registry for my Docker images
+- **CloudWatch** - Monitoring everything (learned this the hard way!)
+
+## ✨ Features I'm Proud Of
+
+- **Clean Architecture** - I spent time learning domain-driven design patterns
+- **Elasticsearch Integration** - Took me a while to get this right, but the search is amazing now
+- **Background Jobs** - Queue processing with Redis (no more slow page loads!)
+- **Self-Healing Database** - The app automatically runs migrations if tables are missing
+- **CI/CD Pipeline** - GitHub Actions deployment (this was a game-changer for me)
+- **Infrastructure as Code** - Everything in Terraform (scary at first, but so powerful)
+- **Container Security** - Multi-stage Docker builds with security best practices
+- **Auto-scaling** - ECS Fargate scales based on demand
+
+## 🛠 What You'll Need
+
+Before you start this journey, make sure you have:
+
+- **AWS CLI** (v2.0 or later) - You'll need AWS credentials
+- **Terraform** (v1.0 or later) - The star of the show!
+- **Docker** (v20.0 or later) - For containerization
+- **Git** - Version control is essential
+
+## 🚀 Let's Get Started!
+
+### 1. Clone My Project
+
+```bash
+git clone [email protected]:Nadeera3784/laravel-10-blog-aws-deployment.git
+cd laravel-10-blog-aws-deployment
+```
+
+### 2. Set Up Your AWS Credentials
+
+```bash
+aws configure
+# You'll need your AWS Access Key ID, Secret Access Key, and choose us-east-1 as region
+```
+
+### 3. Configure Terraform Variables
+
+```bash
+cd terraform
+cp terraform.tfvars.example terraform.tfvars
+```
+
+Now edit `terraform.tfvars` with your values. Here's what I used:
+
+```hcl
+# AWS Configuration
+aws_region = "us-east-1"
+
+# Project Configuration  
+project_name = "laravel-blog"
+
+# Application Configuration
+app_env = "production"
+app_debug = "false"
+app_key = "base64:YOUR_GENERATED_APP_KEY_HERE"  # Generate this with: php artisan key:generate --show
+
+# Database Configuration
+db_name = "laravel_blog"
+db_username = "laraveluser"
+db_password = "YourSecurePassword123!"  # Make this strong!
+
+# Elasticsearch Configuration
+opensearch_master_user = "admin"
+opensearch_master_password = "YourSecureElasticsearchPassword123!"
+
+# ECS Configuration
+app_cpu = "512"
+app_memory = "1024"
+app_count = 1
+```
+
+### 4. Deploy the Infrastructure
+
+This is where the magic happens:
+
+```bash
+# Initialize Terraform (first time only)
+terraform init
+
+# See what Terraform will create
+terraform plan
+
+# Deploy everything to AWS
+terraform apply
+```
+
+### 5. Build and Deploy Your Application
+
+```bash
+# Build the Docker image (make sure it's for the right architecture!)
+docker build --platform linux/amd64 -f docker/php/Dockerfile.prod -t laravel-blog-app:latest .
+
+# Push to AWS ECR
+aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin $(terraform output -raw ecr_repository_url)
+
+docker tag laravel-blog-app:latest $(terraform output -raw ecr_repository_url):latest
+docker push $(terraform output -raw ecr_repository_url):latest
+
+# Update the ECS service
+aws ecs update-service --cluster laravel-blog-cluster --service laravel-blog-service --force-new-deployment --region us-east-1
+```
+
+## 🔧 Running Database Migrations
+
+Here's something I learned the hard way - you need to run migrations separately. Create a new ECS task with the same task definition and override the command in Container overrides:
+
+```bash
+php artisan migrate 
+```
+
+Launch the task, wait for it to complete, then stop it. Your database will be ready!
+
+## To generate local task_definition
+
+```bash
+terraform apply -auto-approve -target=local_file.task_definition
+```
+
+
+Here's something I learned the hard way - you need to run migrations separately. Create a new ECS task with the same task definition and override the command in Container overrides:
+
+```bash
+php artisan migrate 
+```
+
+## 🤖 Setting Up CI/CD (The Cool Part!)
+
+I set up GitHub Actions to automatically deploy when I push code. Here's what you need to do:
+
+### Add These Secrets to Your GitHub Repository
+
+Go to **Settings** → **Secrets and variables** → **Actions** → **New repository secret**
+
+| Secret Name | What to Put | Why You Need It |
+|------------|-------------|-----------------|
+| `AWS_ACCESS_KEY_ID` | Your AWS Access Key | For GitHub to access AWS |
+| `AWS_SECRET_ACCESS_KEY` | Your AWS Secret Key | Authentication |
+| `AWS_REGION` | `us-east-1` | Which AWS region |
+| `ECR_REPOSITORY` | `laravel-blog-app` | Your container repository |
+| `ECS_SERVICE` | `laravel-blog-service` | Your ECS service name |
+| `ECS_CLUSTER` | `laravel-blog-cluster` | Your ECS cluster name |
+| `CONTAINER_NAME` | `laravel-app` | Container name in task definition |
+
+### What Happens Automatically
+
+Once you set this up, every time you push to the main branch:
+- ✅ Tests run automatically
+- ✅ Docker image builds
+- ✅ Pushes to ECR
+- ✅ Updates ECS service
+- ✅ Zero downtime deployment!
+
+## 🏗️ What Gets Created in AWS
+
+When you run Terraform, here's what you'll get:
+
+**Core Infrastructure:**
+- VPC with public/private subnets (security first!)
+- ECS Fargate cluster (no servers to manage)
+- RDS MySQL database with automated backups
+- ElastiCache Redis for caching and queues
+- Elasticsearch domain for search functionality
+- Application Load Balancer with health checks
+- S3 bucket for file storage
+- ECR repository for your Docker images
+
+**Security & Monitoring:**
+- CloudWatch log groups (you'll thank me later)
+- IAM roles with minimal permissions
+- Security groups that actually secure things
+- Encryption everywhere (RDS, Redis, Elasticsearch)
+
+## 🎨 What the Blog Can Do
+
+**For Users:**
+- Read blog posts with beautiful, responsive design
+- Search through posts (thanks to Elasticsearch!)
+- Browse by categories
+- Fast loading (Redis caching works wonders)
+
+**For Admins:**
+- Create, edit, and delete posts
+- Manage categories
+- User authentication system
+- Admin dashboard
+
+**Under the Hood:**
+- Background job processing
+- Automatic database migrations
+- Comprehensive error logging
+- Performance optimizations
+
+## 🐳 Docker Development
+
+Want to develop locally? I've got you covered:
+
+```bash
+# Start everything with Docker Compose
+docker-compose up -d
+
+# Run migrations in the container
+docker-compose exec app php artisan migrate
+```
+
+## 🔍 My Learning Journey
+
+### Challenges I Faced
+
+1. **Docker Architecture Issues** - Learned the hard way about ARM64 vs x86_64 compatibility
+2. **Database Connectivity** - Security groups were confusing at first
+3. **Elasticsearch Setup** - The configuration took several attempts
+4. **ECS Task Definitions** - Understanding CPU/memory allocation was tricky
+
+
+## 🚨 When Things Go Wrong
+
+**ECS Task Failing?**
+```bash
+aws logs get-log-events --log-group-name "/ecs/laravel-blog" --log-stream-name <stream-name>
+```
+
+**Database Issues?**
+- Check security group rules
+- Verify RDS endpoint in environment variables
+- Make sure your password is correct!
+
+**Docker Build Problems?**
+- Always use `--platform linux/amd64` for AWS
+- Check if Docker daemon is running
+
+## 🎯 What's Next?
+
+Some ideas for improvements:
+1. Add CloudFront for faster static assets
+2. Implement auto-scaling based on traffic
+3. Set up proper SSL certificates
+4. Add more comprehensive monitoring
+5. Create staging environment
+
+## 💝 Why I'm Sharing This
+
+I spent weeks figuring this out, reading documentation, debugging issues, and learning from mistakes. If this helps someone else on their AWS/Terraform journey, it was all worth it!
