This project demonstrates end-to-end DevOps automation to deploy a sample Warehouse Management System (WMS) microservice to AWS ECS Fargate, using:

• Terraform for infrastructure provisioning
• GitHub Actions for CI/CD
• Amazon ECR for container image storage
• CloudWatch for centralized logging

✅ Infrastructure-as-Code (Terraform) ✅ CI/CD Pipeline (GitHub Actions) ✅ Secure image storage in Amazon ECR ✅ Automatic task definition revisions ✅ Auto-deployment to ECS Fargate ✅ Centralized monitoring with CloudWatch Logs

Terraform provisions all infrastructure:

• ECS Cluster
• Task Definition
• Service
• IAM roles
• Security Groups
• Log Groups

Tip: See main.tf in this repo for the complete example.

The pipeline is triggered on any push to main. It performs these steps:

1. Checkout Code
2. Configure AWS Credentials
3. Login to Amazon ECR
4. Build Docker Image
5. Tag and Push to ECR
6. Register ECS Task Definition
7. Update ECS Service to deploy the new revision

✅ Pipeline file: .github/workflows/deploy.yml

Configure these GitHub Secrets in your repository:

• AWS Account
• AWS CLI configured locally
• Terraform installed
• GitHub repository with your application code and pipeline YAML

aws ecr create-repository --repository-name wms-sample-repo

terraform init
terraform apply

Terraform will:

• Create ECS Cluster
• Create IAM Roles
• Create ECS Service
• Setup CloudWatch Logs

On push to main, the GitHub Actions workflow will:

• Build and tag your Docker image
• Push to ECR
• Register new ECS Task Definition
• Update ECS Service

• Go to AWS ECS Console
• Confirm your task is running
• Locate the public IP
• Test the app:

curl http://<public-ip>

Logs are sent to CloudWatch Logs under:

/ecs/wms-logs

You can view logs in AWS Console for debugging and monitoring.

This project uses:

• ECS Fargate compute
• CloudWatch Logs
• ECR storage

Remember to delete resources when done to avoid charges:

terraform destroy

or scale the ECS Service to 0 tasks.
